SMT5's inner workings have been generally poorly documented historically. With SMT5V now out, I seek to change this with this guide.

The first step for calculating damage is to get a "Root" value, which is derived from the below formula, depending on whether the attacker is above level 150.


What this effectively means is that each level past 150 counts for only 1/10th what each level up to and including 150 does.
Once Root has been calculated, the game then needs what stat a given skill uses for damage. Included is a table mapping what to use for various skills.


The game takes this stat and uses it to derive an offense based on the following conditions


The game will use this value in a calculation depending on the difference between Offense and Vitality


With Base being no lower than 1.

Once the game determines the base damage, the game will apply a series of modifiers to it

Base is determined by the previous section.

Skill Power is just a power value assigned to the skill used, such as 100 on Heat Wave or 265 on Agibarion. Basic attacks have 100 power (excluding enemy Lahmu and phase 2 Lucifer, who use skills named "Attack" instead).

Some skills will have a separate power value when they crit, or when a condition is met. If this happens for a multihit, it applies to that hit and all hits after. A few skills will have their power value computed though, and those skills are listed below alongside the formula to compute their power.


Attack Stage is the level of Attack buff/debuff on the attacker. Defense Stage is the same thing, except for the Defense buff/debuff stage on the defender.
Doubler inverts Def used due to bug (relevant when triggering counters).

Additionally, there's a number of "Charge" effects, which are described below (none affect counters)

Pleromas are just skills that have Pleroma in the name, and boost damage dealt by skills of a specific element. These skills have the following effect when applicable


Zealot simply refers to multipliers from the skill Critical Zealot. This is a 0.9x multiplier that is always applied (except for on skills that deal level based damage and Vinyl Bomb) and a 1.45x multiplier that is only applied upon landing a critical hit. Note that Critical Zealot is applied even for skills that cannot crit.


Potential refers to the damage multiplier from skill potential. The range of potential values there is
Note that skill potentials do not affect basic attacks, items, or Magatsuhi skills.

Efficacy refers to both the enemy's resistance to the attack's affinity as well as whether the attack was a critical hit. Affinity resistance is usually 0.5x (resist) or 1.25x (weak), but can occasionally be 3x (weak, Tehom/Demi-Fiend). Increase this value by 0.5 if crit.


Level Correction can be calculated using a 2 step process



For nearly all enemies you can't recruit mid-battle, Level Correction is instead 1.0

Difficulty Modifiers are set to the following values


Exploit is the multiplier used when "Omagatoki: Exploit" is in effect. This is 2.1x where applicable.

Enemy Multiplier is an arbitrary value set on a per-enemy basis to damage dealt. Too many to list, but notably Masakado deals 4.0x.
Additionally, when using "Attack", enemy Lahmu will subtract 0.1 from Enemy Multiplier per dead Tentacle.

Guarding gives a 0.8x multiplier to damage taken.

Innates is just the product of all innate skills that are currently affecting damage. Innate skill effects are in their own section.

Modified is rounded down, and can be no lower than 1.

Note that, if an attack is repelled, none of these innate skills will boost or reduce damage except

• Elephantine Ricochet (since it applies explicitly on repel)
  
• Four Oni (since the effect is applied to the charge itself)

Additionally, for Shining Dragon's Scales, Sankosho, Incendiary Stoning, Roaring Mist, Carpet Bolting, Catastrophic Gales, Lighted Wheel, Boon of Slot, and Ceaseless Crucifixion, the damage multiplier has no explicit cap. It does, however, effectively cap at 21,474,836x once the hit counter reaches 2,147,483,484, and overflows to -21,474,836x once the hit counter reaches 2,147,483,548
Getting the hit counter high enough to reach 21,474,836x would take at least 8 years of non-stop play (most likely many more, as this was calculated off the duration of a 17 hit Astral Saintstrike and assuming only 1/60th of a second in-between for menuing), so this cap is not a relevant consideration.

If Shining Dragon's Scales is at that cap, the weakest possible (non-zero) damage value that could be produced while it's in effect (without causing damage itself to overflow and become negative at any step) would be 3 to 6 depending on ranges. This would be achieved by having a low Strength, low level Ippon-Datara or Huang Long (Ippon-Datara and Huang Long both need to be present) use a basic attack via Confusion on a high Vitality, high level Lilith on Safety difficulty while the attacker has Critical Zealot, -2 Attack, and Omagatoki: Doubler and Lilith is guarding while also having Taunt (for Ippon-Datara's innate), -2 Defense, Omagatoki: Doubler, Shield of God.

The following operations are applied to Modified, in order, to get the minimum damage value

Damage dealt to MP (such as by Spirit Drain) instead applies the following operations to get the minimum damage value

Recovery amount begins with a Root value set to
Rounded down. Skill Heal Percent and Skill Heal Power being parameters taken directly from the skill itself.

If "Skill Heal Power" was not 0, then the game then modifies this root value with

Pleromas is just the effect of Heal Pleroma and High Heal Pleroma, which are
Note that Pleromas do not affect MP heals.

Potential is determined by the user's skill potential in the skill used. Potential multipliers are
Note that skill potentials do not affect items, Magatsuhi skills, or MP heals.

The remaining multipliers are (none of the below multipliers affect items, and only Oath of Plenteousness affects MP heals)

"User" in the context of Adversity is somewhat complicated. The time period when Adversity actually generates Current HP / Max HP for healing calculation isn't when the healing skill is actually used, but when the expected recovery value is displayed when selecting the skill's target (only generated when the user has adversity and is not using an item to heal).

If a demon were to use a healing skill without having to go through the menu and select a target, then it would use whatever the last generated healing preview's HP % was (1.0 if it was never generated). This preview is not generated when using a healing skill due to Charm. As a result, this allows for a mismatch with the user's HP % is and what the healing formula thinks it is. For example, you can have a demon at 1 HP and 999 MAX HP select Dia, then not use it and back out, and then have a Charmed demon at full HP use Diarama due to Charm (without selecting a healing skill in the skill list), and it will be treated as being at 1 HP out of 999 MAX HP for the healing formula.

Healing is rounded down.

The final step in calculating Damage or Recovery is to add a random bonus amount. This bonus amount is actually the sum of 2 parts, each rolled separately
MP Recovery is not affected by damage ranges. HP Recovery capable of going above max HP (such as under the effect of Bowl of Hygieia) is also not affected by damage ranges.


The final value for Damage/Recovery is
With a max value of 99,999 for damage
Damaging skills that drain HP instead cap at the lower of the target's remaining HP before the attack connected and the target's max HP, unless that value is more than 99,999. This means that draining attacks such as Eat Whole cannot kill a target with more HP than their max HP under any circumstances.
MP damage instead caps at the target's remaining MP before the attack connected, unless that value is more than 99,999.



A special case can be observed for damaging skills that hit into a "Drain" affinity, where the 99,999 cap isn't actually applied. As a result, this effectively makes Drained attacks uncapped.

Furthermore, if a drained attack's healing value + the target's current HP is more than 2,147,483,647 (again, this is actually achievable in-game), then the target's HP will overflow to a negative number (which the game will then set to 0). This won't kill the enemy, as the behavior for dying won't trigger until taking damage in the conventional sense, so an enemy with 0 HP due to an overflow is functionally equivalent to an enemy at 1 HP (unless, of course, they heal again after).


The RNG generates a random floating point number from 1.0 to 2.0, including 1 but excluding 2, and subtracts 1 from that to get the multiplier used for the damage range. As a result, for each step, there are exactly 8,388,608 possible values the RNG can produce.

Under normal circumstances the most that means is that a 99,998 base damage attack has a 0.00250041% chance to not hit damage cap instead of the expected 0.00250025%. However, with obscenely large uncapped damage values (into a drain) this can be more impactful. For example, if a skill does 2 billion damage at base, then the 5th lowest possible boost from damage ranges is 238 (the 4 lowest being 0, 1, 2, and 3), meaning the values between 2 billion + 3 and 2 billion + 238 can't be rolled.

Repelled damage cannot be made to crit, even by Omagatoki: Critical. Additionally, innate skills do not modify repelled damage aside from Elephantine Ricochet and Four Oni. Additionally, difficulty multipliers used for repelled damage are tied to the defender (so players take 1.3x damage from repels on Hard, for example).

Drained damage behaves much the same as normal damage, with the exception that it cannot crit and is uncapped.

Most damage modifiers, damage ranges included, do not affect Vinyl Bomb. However Vinyl Bomb is still affected by

• Weaknesses/Resistances (irrelevant since it is Almighty)
  
• Omagatoki: Exploit (irrelevant since there are no Almighty weaknesses to strike)
  
• Critical Hits (1.5x), though it must be enabled to Crit via an innate skill, as Vinyl Bomb counts as magic.
  
• Critical Zealot (1.45x) on crit, for an overall 2.175x to damage on Vinyl Bomb upon a successful crit with Critical Zealot equipped. Critical Zealot's base 0.9x multiplier does not apply however.

Most modifiers to healing, including damage ranges, will not apply to MP healing. The lone exception is Oath of Plentuousness

If the damage formula (between damage ranges and enforcing the 99,999 cap) produces a value higher than 2,147,483,647 when damaging HP (which is possible actually), then it will return a negative number, and applying damage altogether will be skipped. If it instead produces a negative number this way before damage ranges, it will instead produce 1 for that stage of damage calculation (can occur before Kannabi Veil is checked, after applying Omagatoki: Savage, and after applying Omagatoki: Adversity).

The "easiest setup" to induce a damage overflow is to setup a 999 Strength, level 150 Arioch using a Crit Dream Fist against a sleeping enemy level 31 Dís on Safety difficulty while Arioch has +2 Attack, Omagatoki: Doubler, Impaler's Glory, High Phys Pleroma, Critical Zealot, Phys Pleroma, +9 Phys Potential, Omagatoki: Exploit, an ally Huang Long, an ally Cerberus/Orthrus/Inugami/Makami that switches out for Mokoi/Pazuzu/Mephisto immediately before Arioch attacks, Omagatoki Savage, 1 HP remaining out of 999 MAX HP, Omagatoki: Adversity, 24 dead allies, and at least 70 total hits for the turn while Dís has -2 Defense.

The max damage possible (before applying the 99,999 damage cap) without using innate skills dependent on the global hit counter would be 1,455,558,163 (similar setup, but uses Leanan Sidhe/Lamia instead of Huang Long), so innates reliant on the global hit counter are required to cause a damage overflow.

The game will start by determining a Root value

An operation is then performed on Root based on if the value is less than 1.

Base is then multiplied by several values

Skill Hit is the hit rate of the skill itself. Can be 50, 88, 98, 100, 108, 118, or 178, though 88 and 178 are extremely rare appearing on exactly 1 enemy each, and 100 is exclusive to Nahobino's basic attack.

If the player is attacking, Level Correction is set to
Unless it would be lower than 1.0 or greater than 1.2, then set it to 1.0 or 1.2 respectively.
When enemies are attacking, level correction is just 1.0

Eye simply refers to the combined multiplier from the passives "Beast Eye" and "Dragon Eye".

Elusive Eclipse refers to the accuracy multiplier when the defender has Elusive Eclipse equipped. This value is 0.95.

Accuracy Stage refers to the Sukukaja level on the attacker, and Evasion Stage refers to the Sukukaja level on the defender. The stages map to the below values.

Difficulty refers to a multiplier applied to each party's attacks based on the difficulty setting. The values for that are

Innates is the product of all innates with effects that modify hit rate


The resulting value of "Raw" will get converted into a new value called "Scaled", the result being dependent on the value of Raw

Finally, 2 more multipliers are applied to get the final hit rate


Except there's a small quirk with the RNG. The way it works is that it will generate a random number from 0 to 32767 (inclusive), then divides it by 32767 and multiplies by 100 (to get it as a %). If your hit rate is greater than the result of this random number, then you hit.

The "Gen 1 Miss" is a commonly recognized oversight in Pokemon Red & Green, Blue, Red & Blue (international), and Yellow where the game rolls all accuracy checks with a random value from 0 to 255, then checks if that value is less than the attack's hit rate, while hit rates for moves that perform accuracy calculation do not go above 255. As a result, since 255 is not less than 255, that means all moves that go through accuracy calculation have at least a 1 in 256 chance to miss in those games.

I bring that up because, since the division is by 32767 and not 32768, one of the values produced by the RNG can be 100 exactly. As 100 is not less than 100, a similar phenomenon is observed in SMT5 where even skills that are supposed to be 100% accurate have a 1 in 32,768 chance to miss. The only exceptions are when bypassing accuracy calculation or when hit rates explicitly go above 100%. The only way for hit rate to exceed 100% is by using Omagatoki: Hit.

Lastly, under the following circumstances, hit rate calculation will be bypassed.
(prioritized in order listed)

Critical rate calculation begins with
Root is no higher than 4.

then uses Root to produce the base rate

then modifies the base rate with

Skill is just the skill's base crit rate. This can be 0, 20, 30, or 200 (note that 200 is incapable of producing a crit rate lower than 100%, but will not bypass the crit formula).

Glee is simply the result of Bloody Glee and Murderous Glee.

Level Correction can be the result of 1 of 3 formulas, depending on difference between the attacker's level and the defender's

Difficulty is the multiplier applied to your crit rate based on the difficulty setting

Innates is the product of all innate skills that affect crit rate

Crit Rate is rounded down to the nearest whole percent.

Under the following circumstances, crit rate calculation will be bypassed.
(prioritized in order listed)

All damage skills use this formula. Strength-based skills can crit naturally (though skills that are strength-based, but have their power scaled relative to max HP, such as Beatdown, do not count as "Strength-based" here), as can any skill with the Physical damage element. Magic-based skills (excluding a hypothetical magic-based Physical skill) can only crit if an innate skill or Omagatoki: Critical allows them to. Level-based skills (excluding Feline Fury, which is level-based Physical) cannot crit, except by Omagatoki: Critical.

The first step in calculating ailment rates depends on both the attacker and defender's luck stats

Then the initial value is modified to

Skill is the base ailment rate of the skill being used. For example, it would be 150% on God's Bow. If multiple effects are contributing to this value (such as Crippling Blow on Matador and Mudoon hitting a weakness), they are added together to produce this value.

Potential is the skill potential that corresponds to the skill being used (not necessarily Ailment potential). These values map to
Note that skill potentials do not affect items or Magatsuhi skills.

Resistance is actually a calculated parameter based on the demon's resistance to the given ailment and the number of times the demon has been afflicted with that specific ailment previously. This is calculated as
no lower than 0
The value of Prior Afflictions is reset to 0 by Dekajaon.
If the ailment is instakill, Resistance is instead always 1.0

Included is a reference for the resistance value with every base resistance/prior affliction count combination

Mask is the effect of Hellish Mask/Abyssal Mask

Instakill Rate Multiplier is an enemy-specific multiplier that affects the success rate of incoming instakill ailments, similar to how a resistance would affect a normal ailment that a demon hasn't been afflicted with yet. Usually this is 0 or 1, but in rare cases may be 0.4, 0.3, 0.2, 0.1, 0.05, 0.02, or even as low as 0.01

Difficulty refers to the way difficulty settings affect ailment/instakill rates. Technically this parameter is different depending on if the ailment is an instakill, however only one table is shown due to the scarcity of differences between the 2

Guarding has a different effect based on the resistance level the demon has to the ailment

Innates is the product of all innate skills that modify existing ailment affliction rates

Raw is no higher than 100%.

Finally, a few more multipliers are applied


Ailment Rate is rounded down to the nearest whole percentage.
Skills with 255 base ailment rate (Mesektet's Path and Magatsuhi Plunder) will bypass this process and always apply their corresponding ailment successfully (Shroud and Instakill respectively).
Ailments will also always fail if Mud, Shroud, or that same ailment is already applied to the target.

Multi-Ailment skills, such as Preach or Accursed Poison, will attempt to apply each ailment individually in a sequence.

The order of this sequence depends on the skill.

For Accursed Poison, this order is shown below.

• Seal
  
• Sleep
  
• Charm
  
• Confuse
  
• Mirage
  
• Poison
  
• Others (only relevant for modders)

For other multi-ailment skills it is

• Shroud (only relevant for modders)
  
• Mud (only relevant for modders)
  
• Mirage
  
• Seal
  
• Sleep
  
• Charm
  
• Confuse
  
• Poison
  
• Death

However, for skills that are not Accursed Poison, whichever ailment has the lowest priority will take the place of a random ailment in the list, including the place it's already in (this is why Death is relevant, as it will always be the lowest priority ailment if the skill can inflict it), then the ailment that was already there becomes the highest priority ailment.

After all the above steps (further steps apply even to Accursed Poison), the ailments are grouped by how strong the target's resistance to them is (Death is always treated as neutral) before accounting for prior afflictions, with less resisted ailments taking a higher priority than more resisted ailments and nulled ailments being removed from the list entirely. The previously generated ailment priority order is preserved among equally resisted ailments.

Death always takes functional priority (and visually can be applied concurrently with other ailments), but still has an impact on how priority order is determined.

To provide just a few examples of how ailment priority works

Accursed Poison vs. Sudama (weak to Sleep, neutral to Charm, Seal, Mirage, and Poison, resists Confuse)

• Sleep > Seal > Charm > Mirage > Poison > Confuse

Preach vs. Slime (neutral to all 3 of Preach's ailments)
one of

• Sleep > Confuse > Charm
  
• Charm > Sleep > Confuse
  
• Confuse > Sleep > Charm

Frenzied Chomp vs. Onmoraki (neutral to all 3 of Frenzied Chomp's ailments)
one of

• Charm > Poison > Confuse
  
• Confuse > Charm > Poison
  
• Poison > Charm > Confuse

Muscle Drink vs. Tzitzimitl (weak to Confuse and Mirage, but neutral to Charm)
one of

• Mirage > Confuse > Charm (2/3)
  
• Confuse > Mirage > Charm (1/3)

Frenzied Chomp (used by Dagda with an Omagatoki effect active) vs. Onmoraki (neutral to all 4 of Frenzied Chomp's ailments when used with Magic Harp), including Death
one of

• Sleep > Death > Charm > Confuse > Poison
  
• Charm > Sleep > Death > Confuse > Poison
  
• Confuse > Sleep > Charm > Death > Poison
  
• Poison > Sleep > Charm > Confuse > Death
  
• Death > Sleep > Charm > Confuse > Poison

which removing Death becomes

• Sleep > Charm > Confuse > Poison (2/5)
  
• Charm > Sleep > Confuse > Poison (1/5)
  
• Confuse > Sleep > Charm > Poison (1/5)
  
• Poison > Sleep > Charm > Confuse (1/5)

And here's a full list of multi-ailment skills

2 possible ailments, not including Death (in effect, which one takes priority here is just random)

• Madness Glint (Seal and Confuse)
  
• Great Lament (Mirage and Poison)
  
• Slumber Vortex (Mirage and Sleep)

3+ possible ailments, with or without Death (these are the ones where the details of the priority order matter)

• Blight w/ Magic Harp (Sleep, Poison, Death)
  
• Dark Sword w/ Magic Harp (Seal, Sleep, Death)
  
• Mist Rush w/ Magic Harp (Mirage, Sleep, Death)
  
• Frenzied Chomp (Charm, Confuse, Poison)
  
• Frenzied Chomp w/ Fear of Death, Crippling Blow, or Moirae Cutter (Charm, Confuse, Poison, Death)
  
• Frenzied Chomp w/ Magic Harp (Sleep, Charm, Confuse, Poison, Death)
  
• Toxic Sting w/ Magic Harp (Sleep, Poison, Death)
  
• Madness Needle w/ Magic Harp (Sleep, Confuse, Death)
  
• Accursed Poison (Seal, Sleep, Charm, Confuse, Mirage, Poison. Uses unique priority order)
  
• Preach (Sleep, Charm, Confuse)
  
• Muscle Drink (Mirage, Charm, Confuse)

Ailment recovery rates begin with a root value determined by the level of the demon with the ailment

Additionally, the game uses a coefficient value specific to the ailment itself

Those 2 values, alongside the demon's Luck stat, are used to compute a base ailment recovery rate
no lower than half of Coefficient, and no higher than 85

Worth noting is that, due to the way Root scales for level values 100 and above, this value can never exceed its minimum for demons at level 103 or higher, so for level 103+ demons "Base" is just 0.5 for Sleep and Poison, and 7.5 for other ailments.
Additionally, while theoretically possible to have a "Base" above the minimum at level 100, none of the level 100 Virtual Trainer battles have the required Luck stat (277 to go above by technicality, 284 to actually affect the final result in any circumstance, 295 to affect the result without Ward Off Evil) for that to be the case at level 100.

And the final rate being

Elapsed Turns is the number of full turns that the demon's party has completed since receiving the ailment. So if a demon is inflicted with an ailment, the turn goes back over to their side, then back to the initial side, then back to side with the ailed demon, this value is 1.

Innates is the product of all innate skills that affect ailment recovery rate

Ailment Recovery Rate is rounded down to the nearest whole percent.

The check is run only if Elapsed Turns is at least 1 (at least 2 in the case of Shroud), and occurs at 2 points. The first time this check is performed is at the start of the ailed demon's turn. The 2nd is immediately before the demon's party ends their turn, passing control to the other party (this uses the same Elapsed Turn counter as the checks earlier in the turn would have).

Additionally if a sleeping enemy takes damage from an attack, and the attacker does not have Unending Nightmare, then Sleep will be immediately cured.

Poison damage, much like normal damage, starts with a "root" value
Root is rounded down for Poison specifically.

The base poison damage rate is determined by

Difficulty is the same as it is for other forms of damage

Random is derived from the sum of random numbers A and B
Base is rounded down.

Finally the multipliers from Poison Adept and Poison Master are applied. Said multipliers are

Shroud's MP Penalty starts with a "root" value similar to Poison's.
Rounded down, and no lower than 1.

That root value is then used to calculate Shroud's MP damage as

Difficulty is the same as it is for other forms of damage

Random is derived from the sum of random numbers A and B

Damage is rounded down, and cannot be lower than 1.

In practice, since there's only 1 way for Shroud to be applied, this means that Shroud MP damage can be mapped to (VT followed by a number "n" means Virtual Trainer Level n)

These effects have already been mentioned earlier in the guide

• Poison dealing damage to afflicted after afflicted acts
  
• Mirage lowering accuracy when on attacker
  
• Confuse, Charm, and Sleep completely disabling evasion when on the defender
  
• Shroud dealing MP damage to afflicted before afflicted acts

The below effects have not been mentioned elsewhere

Mirage has a chance to cause attacks to be directed at a target other than the selected target where applicable.

Confuse has a chance to replace the afflicted demon's action with another action

Magatsuhi Harvest and skills that summon reinforcements are not affected by this.

Charm has a chance to replace the afflicted demon's action with another action
Note that, should a demon be unable to perform a given action through Charm, then the odds of that event occurring get added to the event directly above. For example, if the demon does not have a Recovery skill, then the odds of using a Support Skill on enemies normally become 30%. If the demon can use a Recovery skill, but not a Support skill, then the odds of doing nothing becomes 30%.

A "Recovery" skill for the purposes of Charm is defined very narrowly, only including a specific variant of Dia, Diarama, Media, or Mediarama. The skill must be in the demon's displayed skill list to count, and has different effects depending on which side of the battle is using the skill.


It is worth noting that the game is picky about which variant of the skill an enemy must have in order for the skill to be select-able though Charm. As such, only the following enemies can heal the player due to Charm.


A "Support" skill is also defined very narrowly, only including the following skills.


If multiple legal options exist for either group, the skill selected within that group is random with evenly distributed odds.

Magatsuhi Harvest and skills that summon reinforcements are not inhibited by Charm.

Charm and Confuse will disable any "Counter" type skills, such as Counter, Retaliate, Heavenly Counter, Vinyl Bomb, Adversary, etc.

A sleeping demon will be unable to do anything whatsoever. Unlike Confuse, Charm, or Seal, there are no skills that bypass this restriction.

A sealed demon will be unable to use any skills select-able from the skill menu except for the basic attack. Enemy demons that are sealed will instead skip their turn when they attempt to use one of those skills.

Magatsuhi Harvest, skills that summon reinforcements, skills that are presented as though they were items, and skills that are presented as though they were basic attacks are not affected by this. On paper, the attack part of counters are not affected by this either, however the triggers for said counters cannot activate while sealed.

Before a character with Mud acts, they will lose 1 press turn icon. Contrary to what the English description says, there is no chance to fail to act with Mud.

Hit counts on skills are divided into 3 parts. Min Hits, Max Hits, and sometimes Per-Target Max Hits.

The following skills modify at least one of the above values (where applicable), in this order

When determining how many hits a skill should have on any one use, the game generates a random number from Min Hits to Max Hits, with all potential values being about equally likely.

If Per-Target Max Hits is set, and the resulting hit count is greater than then the number of hits will instead be that value.

Events like critical hits will be checked per hit on multihits, however hit rate and ailment affliction rate are only checked on the first hit per target, and you only get Magatsuhi once from hitting weaknesses/crits at all with the action.


Behind the scenes the game keeps track of a party-wide counter for the number of times a party member has hit something since that party last began a turn, which is used for certain innate skills like Sankosho or Shining Dragon's Scales. A hit is defined by a single instance of non-Poison damage (the intuitive definition) or by successfully inflicting an ailment with a non-damaging skill. This counter is uncapped.

The below skills have a % chance (below 100) to activate. Trickery, when it applies, multiplies activation rates by 1.3 x the number of demons in the active party with Trickery (so 1.3x with 1, 2.6x with 2), then rounds down to the nearest whole percentage.

The bar is split into 100 units (therefore 1 unit is 1%). Here's how much each condition builds, and the requirements in order for that condition to apply.


Additionally, only one of the following can apply on any 1 action (largest value selected if multiple conditions are met)

• Fell Swoop (Weakness)
  
• Fell Swoop (Critical)
  
• Counter Incentive: Resist
  
• Unyielding Will
  
• Counter Incentive: Null (Null)
  
• Counter Incentive: Null (Repel)
  
• Counter Incentive: Null (Drain)
  
• Vengeance

If multiple Counter skills trigger off a given attack, the following process is used to determine which one activates

If an innate skill counter (such as Tempest or Vinyl Bomb) activates, that will always take priority.

Otherwise, the counter with the highest power will take priority (Retaliate is 150 power).

If the only counters to trigger are Counter and Heavenly Reversal (both 100 power, non-innate counters), then the one that is listed first in the demon's skill list will take priority.


When Demi-fiend attacks, the following innate skills are prevented from taking effect

• One-Foot Hop (cannot lower damage dealt or hit rate)
  
• Bountiful Earth (cannot lower damage dealt)
  
• Qadištu Mandate (cannot lower damage dealt)
  
• Qadištu Deception (cannot lower hit rate)
  
• Impenetrable Purity (cannot remove Piercing effect from attacks)
  
• Tablet of Destinies (cannot null physical attacks)
  
• All innate counterattack skills (such as Tempest, Vinyl Bomb, or Adversary)

MP Cost Modifications are applied in the order of

• Skill Potential
  
• Innate Skills (product of multipliers)
  
• Omagatoki: Savage

rounding down after each step. However, each multiplier other than Savage is slightly lower than it should be on paper (due to floating point imprecision), resulting in MP costs 1 lower than they should be at several points.

The most notable example is that if a multiple of 5 is multiplied by 1.6 (min potential), 1.2 (-1 Heal/Support, -4 for others), 0.8 (+2 Heal/Support, also Okuninushi's Teachings) or 0.6 (max potential), then it will be 1 lower than expected at that step of the calculation. There are other more niche examples, and listing all of them would take too long.

For those looking to calculate exact numbers, start with any multipliers from skill potential/innate skills at 100x their expected value and multiply by 0.01, performing all operations on 32 bit floating point numbers.

Generally speaking, the primary effect Taunt has is to redirect attacks towards the Taunt bearer at
rounded down to the nearest whole percentage.

If multiple allies have Taunt and succeed their redirection check, the one who moves earliest on the player turn will take priority.

Several enemies also exhibit additional behaviors in response to Taunt, such as avoiding targeting weaknesses, changing what skills they use, guaranteeing they target a Taunt user, etc.

In rare cases, some enemies will completely ignore Taunt when using certain skills even when using skills that target "1 foe", those instances are listed below.



Below is the multiplier applied to EXP based on how many levels the demon is behind the enemy.


Drained attacks ignore the damage cap.

Usually drained attacks will scale the same way neutral attacks do, with a 1.0x multiplier. However, if all of

• Demon naturally drains the element
  
• Demon does not have a passive that adds null, repel, or drain for that element
  
• Demon has the passive that adds resist for that element

are true, then drained attacks will work with a 0.5x multiplier instead.



Notably, the way the conditions are set up for each Charge type. Using Feline Fury with Critical Aura will result in the effect of Critical Aura being applied, but Critical Aura itself not being consumed.

Feel free to let me know if there's anything I overlooked, or got wrong (ideally with either proof or a test scenario I can use to verify your claim), or should include but haven't.

Additionally, here's a few data tables I'm working on for the game. They're far from finished, but should be a useful reference.
