ネクロバインダー

• Type: Skill
• Cost: 0
• Effect: This turn, whenever you play a card, apply 3 Ruin to an enemy.

A cost 0 Skill that applies 3 Ruin to an enemy for each card played that turn after placement. The more cards played, the more Ruin stacks: 5 cards after Oblivion add 15 Ruin, 10 cards add 30.

It is the key card of Ruin decks, stacking Ruin alongside Countdown (6 Ruin per turn) and Reaper Form (Ruin equal to attack damage), then releasing with Finale (Exhaust for damage equal to Ruin) or Doomsday (apply 29 Ruin AoE, lethal if it exceeds HP). Being cost 0 means no Energy spent, so playing it at the start of a turn with many cards maximizes the effect. Combining with Misery (spread one target's debuffs to all) can scatter massive stacks of Ruin to every enemy.

Rating: 4/5 (cost 0 engine that stacks massive Ruin; peak value early in big turns)

• Play Oblivion first, then pile on as many cards as possible to stack Ruin
• Maximizes on turns with lots of playable cards (big hand or many cost 0 cards)
• Release the stored Ruin with Finale or Doomsday for massive burst
• Use Misery to spread accumulated Ruin on one target to all enemies at once

• Finale: Deals damage equal to Ruin and Exhausts; finisher that releases Oblivion's stacks
• Doomsday: Applies 29 Ruin AoE, killing any enemy whose HP is below the Ruin; Oblivion first makes lethal easier
• Misery: Spreads debuffs to all; Oblivion-stacked Ruin is propagated to every enemy
• Reaper Form: Power applying Ruin equal to attack damage; pairs with Oblivion to stack massive Ruin in one turn
• Countdown: Power applying 6 Ruin to a random enemy each turn; combined with Oblivion for rapid stacking
