Doom
New in STS2Instant kill threshold · Necrobinder
Doom is the Necrobinder's signature mechanic. Stack Doom on an enemy and when their current HP drops to or below their Doom value, they are instantly killed — bypassing all remaining HP and ignoring block.
How It Works
Stacking Doom
Many Necrobinder cards and powers apply Doom stacks to enemies. Doom stacks accumulate across turns and do not expire. The Doom value is displayed on the enemy.
Instant Kill Trigger
When an enemy's HP is reduced to a value equal to or less than their current Doom stacks, they die instantly. This means you can set up a Doom threshold and then chip the enemy down to trigger it.
Block Interaction
The instant kill triggers based on HP, not damage dealt. Block does not prevent the Doom kill — once HP hits the threshold, the enemy dies regardless of block.
Co-op Synergy
In co-op, all players can contribute Doom stacks to the same enemy. A Necrobinder player stacking Doom while teammates deal damage is one of the strongest co-op combos in the game.
Tips
- ▸Prioritize Doom-stacking cards early — the threshold needs time to build up.
- ▸Pair Doom with cards that deal small, consistent damage to chip enemies down to the threshold.
- ▸Against bosses, aim for a Doom value of 30–50% of their max HP for a reliable mid-fight kill.
- ▸In co-op, communicate with teammates so they don't accidentally kill an enemy before Doom triggers.
Key Synergies
Osty's attacks chip enemies down toward the Doom threshold each turn.
High-damage Sacrifice cards can close the gap to the Doom threshold in one turn.
Reducing enemy Strength lowers their damage output while you build Doom stacks safely.
