• Cost: 2
• Effect: Whenever you apply a debuff to an enemy, deal 13 damage to that enemy.

A Power that fires 9-13 damage every time a debuff lands on an enemy. Necrobinder's debuffs include Decay, Weak, and Vulnerable, so every card that applies those effects becomes a damage trigger.

Against Deathbringer (AoE Decay + Weak), Negative Wave (AoE Decay), Nowhere to Run (stacks Decay), Defiance (Weak), and Rot (Weak + Vulnerable), a single card can fire 9-13 damage multiple times per play. In multi-enemy rooms, AoE debuff cards produce enemy-count × damage — scaling explosively.

Rating: S-tier (peak debuff-deck Power, turns every debuff applicator into a damage dealer)

• Set it up as early as possible — every debuff card becomes a damage trigger
• Deathbringer (21-26 Decay + 1 Weak) on one target = multiple debuffs × 9-13 = 27-39 damage burst
• AoE debuff cards (Negative Wave, Deathbringer) scale with enemy count — trash fights die instantly
• Rot (2 Weak + 2 Vulnerable + Exude) = 4 debuff applications = 36-52 damage off one card

• Deathbringer: Decay + Weak to all. With Curse Flesh Trick out = enemy count × multiple triggers
• Rot: 2 Weak + 2 Vulnerable + Exude. 4 debuff applications = 36-52 damage
• Negative Wave: AoE Decay + Block. Multiple triggers across every enemy
• Defiance: Ethereal Weak + Block. Defense card that also deals 9-13 bonus damage
• Debilitation: doubles Weak / Vulnerable. Amplified debuffs still stack Curse Flesh Trick damage

• Necrobinder Decay Stack Build (A-tier)
• Necrobinder Passive Decay Scaling Build (B-tier)
