The short answer
The Watcher is not in Slay the Spire 2 yet. She was the fourth character in the first game. In the sequel’s early access, the cast is five characters, and her slot is filled by a new hero.
The five characters in STS2
STS2 opens with Ironclad unlocked. You meet the rest by clearing runs:
| Order | Character | How you unlock |
|---|---|---|
| 1 | Ironclad | Available from the start |
| 2 | Silent | Clear a run with Ironclad |
| 3 | Regent | Clear a run with Silent |
| 4 | Necrobinder | Clear a run with Regent |
| 5 | Defect | Clear a run with Necrobinder |
Defect sits in the fifth slot here. In the first game Defect was third, so the order shifted when the new characters joined.
Why the Watcher is missing
Mega Crit rebuilt the cast for the sequel. Two new characters — Regent and Necrobinder — joined the returning three. The Watcher was left out of the early-access build.
That does not mean she is gone for good. Early access is a growing roster, and Mega Crit has added characters during the period. We update this page the moment she is announced.
What to play instead
If you liked the Watcher’s stance-switching, try Necrobinder. She builds a board of summoned helpers and statuses rather than swapping stances, but she rewards the same planned, layered play.
If you want a familiar face, Defect carries over with orb-like energy mechanics reworked for the sequel.
Will she return?
No date is public. The safe assumption for now: plan around the five characters above. We check the official roadmap each patch and add the Watcher the day she is confirmed.
