Defend

Defend (Watcher) is the purple version of the universal starter skill: 1 Energy, 5 Block (8 upgraded). It's as vanilla as Block gets. The Watcher's defensive tools are more interesting — Calm stance passively prevents incoming damage from being doubled, and cards like Protect and Swivel offer Block with extra benefits — but having Defends available in Act 1 at least keeps you alive.

Once your Watcher deck starts flowing between stances reliably, purple Defends become dead weight. Replace them when better Block options or utility skills appear. Upgrading is rarely the best use of a Smith visit for the Watcher.
