Devolution Serum is a passive item in Ephemera, a mod for The Binding of Isaac.
Adds a chance to fire a reroll tear that devolves the hit monster into a weaker variant of themself.
Each type of monster has a specific devolve path it takes.
If a monster is at its weakest level, it will mostly transform into a background critter or simply die.
Some enemies can be transformed into obstacles or pickups.
The chance to fire a reroll tear starts at 5% with 0 luck and maximizes at 50% with 18 luck.
