Reaper Form

NecrobinderPowerRare
Whenever Attacks deal damage, apply that much Doom.

Applies Reaper Form: any attack from you or Osty gives the target Doom equal to its full damage, blocked damage included.

  • Multi hit: attacks apply it per hit, and a second copy doubles the ratio.
  • Doom: never decays and kills the enemy at the end of its turn once it equals its HP, so every point of attack damage is dealt twice.
  • Upgraded: gains Retain.

When to take Reaper Form

A win condition for an attack-heavy Necrobinder, halving the effective HP of everything it hits. Its 3 cost wants Energy support, so it is usually an Act 2 pickup.
