• Type: Attack
• Cost: 2
• Effect: Deal damage equal to the target's Decay. Exude.

A 2-cost Attack that deals damage equal to the target's Decay stacks, then Exudes (one-shot). Designed as the explosive finisher of Decay decks — pile Decay first, fire Final Hour for one massive hit.

Decay 50 = 50 damage, Decay 100 = 100 damage — unbounded scaling. The plan is to stack Decay across multiple turns using Reaper (Decay = Attack damage), Countdown (turn-start random-enemy Decay 6), Oblivion (Decay 3 per card played), Doomsday (Decay 29 to all), then unleash with Final Hour. Exude means one shot, so timing at peak Decay is key — hundreds of damage on the right turn is very real. Call of the Void (Exude adds damage) also pumps out extra damage when Final Hour itself Exudes.

Rating: S-tier (ultimate Decay-deck finisher, can single-shot end combats)

• Spend several turns loading Decay with Reaper, Countdown, Oblivion, then release with Final Hour
• Because of Exude, one chance only — time it to the peak Decay turn
• Post-Doomsday (AoE 29 Decay) chained with Final Hour can one-shot enemies
• Reaper auto-stacks Decay on every Attack, so high-damage swings set up Final Hour passively

• Countdown: Decay 6 to random enemy each turn. Buys time to load Decay before Final Hour
• Reaper: apply Decay equal to Attack damage. Big hits automatically pile Decay for Final Hour
• Doomsday: Decay 29 to all + instant-kill. Chain Final Hour after Doomsday for 29+ additional damage
• Oblivion: Decay 3 per card played. Fast Decay buildup on busy turns
• Call of the Void: extra damage on every Exude. Final Hour's own Exude triggers it
