This is a work in progress, as there as some unanswered questions about the process. Any feedback to answer these questions or correct misinformation is appreciated.

Step 1
Beat the Act 3 boss with all four Dice Slingers (heroes)

Step 2
a) Find the purple glowing signpost event in Act 1. (after you've beaten act 4 for the first time, this step will be removed)

b) Take the choice to get the Truesight Orb artifact.


Next two steps are concurrent and can be done in any order.

Step 3a: Find the 1st key fragment
a) Defeat the Glowing Elite in Act 2 or Act 3.

b) Choose the Sunstone spell reward.
c) Cast the Sunstone spell on a Boss (Act 2 or 3) before it dies. Killing the boss will now give you the key part, and the Sunstone spell will disappear. Don't forget to replace the Sunstone spell with a new spell!

Step 3b: Find the 2nd Key Part
a) Buy the Void Essence potion in the shop in Act 2 or 3.

b) Have a shard ready to sacrifice (you can disenchant an upgraded spell for it) Looks like this step was removed in the update. No more shard needed!
c) At a Sanctuary, choose the option to sacrifice the void Essence potion and a shard for the key part.


Step 4: Defeat the Act 3 Boss
Get ready for the next act!

8. Vorth'Korr the Progenitor
1st battle: 2 Lesser Star Soul (100 health) & 1 Greater Star Soul (160 health)
All three have the following traits:
- Unfocused: Becomes Focused if targeted by a spell
- Focused: Deals 2x Damage. Becomes Unfocused if another enemy is targeted by a spell.
So try to cast your last spell on the Star Soul that is not attacking.

2nd battle: Vorth'Korr the Progenitor (900 health).
The super final boss!
His pattern includes:
- 10x3 attack
- 5 Power and summon
- 40 attack

He has 2 Nullify (ignores first 2 status effects).
It summons Watching Eyes (100 health) which can gain various annoying status effects (such as 2 Watching (on dice spent, deal x damage), apply 1 Vex.
