Upon entering a room, each enemy has a 20% chance to be petrified for 4 seconds. Enemies that have been petrified by Ice Cube are frozen when killed, including those killed up to 2 seconds after the petrifaction effect ends.
The chance for enemies to be petrified increases with luck, reaching 100% at 40 Luck.
Notes
Enemies spawned in waves are not petrified.
Bosses can be petrified, but cannot be frozen.
Every room has a predetermined set of enemies that are going to be petrified. Re-entering the room will not change this, similarly to Champion enemies.
