Curse

Being Cursed In Dead Cells is a punishment on the beheaded for angering the gods. They cause damage to one-hit kill the player, and must kill a certain amount of enemies to cure it.

The amount depends on the source of the curse and the amounts stack. There are a few different ways to gain curse. Curse sources are risk-reward choices that can greatly benefit the player with rewards being Scrolls, Gems and healing. Curse also has synergies with some weapons and Mutations.

Insta-kills
The following damage sources insta-kill while Cursed:


 * Any enemy hit that deals at least 1 damage
 * Any trap hit
 * Jumping into a bottomless pit
 * Poison DoT
 * Damage from using Lightning Bolt too long
