Dark Harvest

Dark Harvest is a Shadow Power card that applies 4 Poison whenever you exhaust a card. This trigger synergizes with every Exhaust card in your deck: Blazing Sacrifice, Shadow Execution, Purifying Flame, and status cards that self-exhaust like Burn. Phoenix Feather gives +1 energy per exhaust alongside the Poison, creating a powerful exhaust engine.

At level 3 the Poison per trigger increases by 1, and at level 5 it also applies Mark, making exhausted cards generate both damage-over-time and damage amplification. Mirror of Bonds relic causes the first Power to trigger twice, doubling the initial Poison. Remember the max 3 Power limit, so plan your Power slots carefully alongside Feel No Pain and other Powers.

Best in exhaust-heavy builds that generate many exhausts per combat through status cards and Exhaust keyword cards.
