Swivel

Swivel is a Watcher uncommon skill that gains 8 Block and makes your next Attack cost 0 for 2 energy. The Block is solid, and the 0-cost attack follow-up provides a free offensive play on top of the defense. If that free attack is a strong one — like Sands of Time, Signature Move, or Windmill Strike — the combined value of 8 Block plus a major free attack is exceptional. Swivel essentially converts energy into both defense and offense simultaneously.

Swivel pairs especially well with expensive attacks. Making Sands of Time or Signature Move cost 0 effectively gives you an extra 2-4 energy worth of value on the next attack. In Wrath stance, that free attack deals doubled damage, compounding the benefit. The 2-energy cost of Swivel itself is steep, but receiving 8 Block plus a free expensive attack more than compensates. Upgraded, Swivel gains 11 Block instead of 8, improving the defensive return while retaining the same free-attack bonus.
