Reaper Form
Reaper Form is the Necrobinder's 3-cost rare Power Reaper Form. Once it is on you, every time an Attack from you or Osty deals damage to an enemy, that enemy gains Doom equal to the damage of the hit multiplied by the stack. The damage counted is the total before Block is subtracted, so hitting a shielded enemy still stacks Doom. A second copy doubles the Doom per hit.
Where it comes from
Cards that apply Reaper Form
Notes
Only powered attacks qualify, so Poison ticks, relic damage and power damage such as Serpent Form apply no Doom, and a hit that deals 0 applies nothing. Multi-hit Attacks apply Doom on each hit. Since you are recorded as the applier, every hit also triggers Shroud and Sleight of Flesh if you have them. The upgraded card gains Retain rather than a larger number.
Rules and timing
It only counts damage from Attack cards and enemy attacks. HP loss and damage dealt by relics, potions and other powers do not count.
If you haven't bought Slay The Spire 2 yet, it's time. Support the devs, they made an amazing game.
