Poison

Poison

Debuff
Poisoned creatures lose HP at the start of their turn. Each turn, Poison is reduced by 1.

Poison is a counter on a creature. At the start of that creature's turn it loses HP equal to its current Poison, then the counter drops by 1. The loss is dealt as damage that ignores Block and is not scaled by Strength or the attacker's other powers. Stacks from every source add together, so a creature at 7 Poison takes 7 now, 6 next turn and so on.

Notes

Accelerant adds extra ticks per turn, each followed by its own decrement, but never more ticks than the creature has Poison; an enemy reads Accelerant from its opponents because the buff sits on the player. Once the creature dies, remaining ticks do nothing. The counter is drawn in the normal cream color. Sources include Deadly Poison, Noxious Fumes, Envenom, Snecko Skull, Twisted Funnel and Poison Potion.

Rules and timing

Its number is drawn in the normal cream colour, not the red of other debuffs.
