Judgment

Judgment is a Watcher rare skill that causes an enemy to lose HP equal to its current HP for 1 energy, effectively dealing damage equal to half the enemy's remaining health (since the loss is applied to the current value before the hit). Wait — the exact mechanic is that the enemy loses HP equal to its current HP, which at face value means it instantly reduces them to 0, killing them outright. This functions as an instant-kill for any enemy below a certain HP threshold, or a massive damage spike at any health level.

Judgment is most reliably used as a finisher on weakened enemies — when an enemy has been worn down to a low HP pool, Judgment eliminates them instantly regardless of how much damage you've dealt. It's extremely powerful against multi-enemy encounters where you can whittle down multiple enemies and clean them up efficiently, or against bosses you've reduced to low health. The 1 energy cost is incredibly efficient for such a potentially fight-ending effect. Upgraded, Judgment adds a flat 3 HP to the loss calculation, making it slightly more effective even at high enemy HP values.
