• Gives every auto attack the same properties as her ability. Huge range, infinite penetration.

Master of Dreams : Change a cluster of enemies into kedamas.

• The kedamas created appear to have some form of scaling but they still keep extremely low stats. Ex : Wave 100 kedamas have ~700hp, wave 110 ~1000hp.
  
• Like Eiki's instant kill, this won't work on bosses or elite enemies

Rabbit Leader : Teaches Kaguya's lunar rabbit squads and Reisen how to use carrot missiles.

• Carrot missiles are heat seeking missiles with unreal (infinite?) range. They also apply an armor down debuff
  
• Effectively changes the mortar rabbit that kaguya's lvl5 spawns into carrot missile units
  
• Reisen's normal bullets are replaced by carrot missiles
  
• Needs more testing when it comes to damage values, it is a very hard blessing to get, and usually appears late which make testing difficult

Tulip Alraune ：The fairy will often offer a gacha capsule. Very rarely, will offer a bomb instead.

• The cooldown between each "offering" is surprisingly short. A bit less than a minute on x2 speed
  
• Patch notes mention that gacha capsules are the only possible drop. Unsure if getting a bomb is a bug or a flavor interaction.

This was made using the little knowledge i have about the game and with the help of a friend

This started as a way for me to double check some interactions while teambuilding, and to get around the localization bugs, but figured i'd publish it as a steam guide. No harm in doing so and it would bring some life to that section.

Good luck in climbing the leaderboard!
