Dichromatic Butterfly item
Dichromatic Butterfly is a passive item in Fiend Folio, a mod for The Binding of Isaac.
Description
-80% hitbox size, which is now indicated by a red dot near his legs.
When an enemy projectile nearly misses Isaac, he gets +0.2 damage for the rest of the room. This can happen up to 15 times per room, capping at +3 damage.
Grants a luck-based chance to fire an amulet tear that deals 1.25x Isaac's damage and has a very high homing effect.
The chance to fire an amulet tear starts at 16.67% with 0 luck, and goes up to 63.33% with 7 luck. The formula used is random(0, x) < 5 + (luck × 2), where x = 30.
