Pressure Points
Pressure Points is a Watcher common skill that applies 4 Mark to an enemy, plus 4 additional Mark if that enemy already has Mark. Mark is a unique status that causes enemies to lose HP equal to their Mark stacks at the end of each turn. Stacking Mark consistently deals increasingly large amounts of HP loss per turn, bypassing Block entirely. The first cast applies 4 Mark; each subsequent cast while Mark is already present applies 8 Mark (4+4), creating a rapidly escalating damage-over-time effect.
Pressure Points is the cornerstone of a Watcher Mark build. With 2-3 copies, you can stack Mark rapidly in early turns, and enemies will take 8, 16, 24, or more HP damage per turn afterward without you needing to spend any additional resources. Weave (0-cost attack that triggers Mark on all enemies) lets you trigger Mark early in the game before stacking more. The strategy is especially effective against high-health enemies and bosses. Upgraded, Pressure Points applies 6 Mark per cast (12 if Mark is present), dramatically accelerating the stack rate.
