Conclude

Conclude is a Watcher uncommon attack that deals 12 damage to all enemies for 1 energy but ends your turn immediately after. The AOE damage is exceptional for the cost — 12 to all enemies for 1 energy is among the best AOE damage ratios in the game — but ending your turn means you forfeit any remaining plays or energy. In Wrath stance, this becomes 24 AOE damage, which can wipe out or cripple entire groups of enemies in one play.

Conclude works best as the final play of a turn, played after you've already used your other cards. The mandatory turn end becomes a non-issue when you've exhausted your hand or used all meaningful cards. In Wrath stance, Conclude's burst damage is so high that it often ends fights in one play, making the turn-end penalty irrelevant. It's strongest in decks that deal damage quickly and want a decisive finisher. Upgraded, Conclude deals 16 damage to all enemies instead of 12, or 32 in Wrath, making it one of the most damaging single plays available.
