Dead Cells

Crits heavily on mobs with less than 50% health, but, if you don't kill with an attack, you get cursed.

Fires a very heavy curved projectile that explodes on contact. However, you get cursed if you hit anything with it.

Summons a ray of light on a near enemy dealing heavy damage, after a rather long cast. Killing an enemy with it clears 3 stacks of Curse instead of 1.

It will deal Critical Damage if you are not Cursed, or will summon an additional ray for each 5 Curses you have.

Cursed Flask. The Health Flask no longer consumes a charge when used, but will give you 10 Curses instead.

Damned Vigor. Prevents your death and puts you at 1 HP. You have 2 seconds to kill an enemy to save yourself, otherwise you die (for real this time).

Demonic Strength. Increases your damage by 30% if you are Cursed, with +1% per Curse stack.

Sore Loser. A small enemy that cannot deal any damage, but is really sticky and annoying. Killing it will curse you.

Curser. Shoots guided cursed skulls in your direction, with a melee attack if you get too close.

Doom Bringer. Curses you with her damageless melee attack, or can ring her bell to stun you. If she hits you with more than 50 curses, you die.

Those mobs are a bit special, as they don't have a specific biomes in which they spawn. Instead, depending on the Boss Cells level, they have a small chance of appearing in any biome:

Before 2BC, they cannot spawn at all.

In 2BC, Sore Loser and Curser can spawn in biomes at depth 4 or more, while Doom Bringer can spawn in biomes at depth 5 or more.

In 4BC and 5BC, they can spawn in any biome.

And implemented a new "Cursed Biome" mechanic. In short, every biome has a chance to be "Cursed", which means that they will spawn a small quantity of Cursed Mobs, BUT they will also have a +10% chance to spawn a Cursed Chest, and a +1 bonus to their loot level.

If a biome is cursed, a skull icon will show up above the exit door leading to it. It is not possible for all the accessible exits in a level to be cursed, as such, there will always be the possibility to choose a non-cursed path.

The maximum number of cursed biomes in a run depends on the current boss cell level. Note that this number only counts down when entering a cursed biome. Also, some biomes, like the Bank or Boss Levels, cannot be cursed. Update 35.3
