ネクロバインダー

• Type: Power
• Cost: 1
• Effect: At the start of each turn, apply 6 Ruin to a random enemy.

A cost 1 Power that automatically applies 6 Ruin to a random enemy at the start of each turn after placement. Ruin is a debuff that deals damage at end of turn, stacking across turns into big damage.

Efficiency drops in multi-enemy fights because applications are random, but in single-target fights like bosses, 6 Ruin per turn compounds into major passive damage. Paired with Reaper Form (Power applying Ruin equal to attack damage), single-target Ruin totals skyrocket. It sets up Ruin finishers like Finale (Exhausting attack dealing damage equal to Ruin) or Doomsday (apply 29 Ruin AoE, lethal over HP). Combined with Oblivion (3 Ruin per card played) it stacks Ruin at breakneck speed.

Rating: 3/5 (passive Power applying Ruin each turn; useful support in Ruin decks)

• Play it early in Ruin decks to stack Ruin over the long haul
• Combine with other Ruin sources like Reaper Form or Oblivion for explosive buildup
• Since Finale Exhausts, maximize Ruin before playing it
• Use Countdown to edge toward Doomsday's lethal threshold (Ruin over HP)

• Reaper Form: Power applying Ruin equal to attack damage; pairs with Countdown to max Ruin buildup
• Finale: Deals damage equal to Ruin then Exhausts; released all at once via Countdown's banking
• Doomsday: Applies 29 Ruin AoE, lethal if Ruin exceeds HP; Countdown's stacks bring the threshold close
• Oblivion: Applies 3 Ruin per card played; same-turn combo floods Ruin
• Misery: Spreads one target's debuffs to all; spreads Countdown's stacks
