Consecrate
Consecrate is a Watcher common attack that deals 2 damage to all enemies for 0 energy. As a free AOE card, it provides useful chip damage against groups and synergizes with Wrath stance by doubling the damage to 4 to all enemies. While 2 damage to all enemies is modest in isolation, the cost of 0 energy means it fits into any turn without displacing other plays. In multi-enemy encounters, it deals cumulative damage across all targets for free.
Consecrate gains most of its value in the context of the Watcher's stance system. In Wrath, the doubled damage means 4 AOE for free, and using it while transitioning stances can maximize value. It also benefits from Strength scaling, making it better when buffed. Upgraded, Consecrate deals 5 damage to all enemies instead of 2, which is a substantial improvement — 5 free AOE damage is competitive with many dedicated AOE attacks at higher cost, and in Wrath that doubles to 10 to all enemies for zero energy.
