Doom

Doom

Debuff
At the end of the enemy turn, if it has at least as much Doom as HP, it dies.

The Necrobinder's kill counter. It never lowers HP on its own. Just before the end of the owner's turn, if its current HP is less than or equal to its Doom, it dies. Every doomed creature on that side is killed in one batch, triggered by the first of them, so revive effects see all of them at once. Doom never decays and stacks without limit.

  • Potion of Doom applies 33.
