📋 About This Mod
Help me fix bugs:
Currently in a early play test phase, dont expect every interaction / multiplayer to work perfectly. If you find any bugs, just send them here via the 'Bugs' tab or on github.
it would be good to add %appdata%/SlayTheSpire2/logs/godot.log then, so i can see the error / stacktrace.
(or type showlog in the in game console (Shift + 8, ^ or ~ depending on keyboard layout) and send me the red messages)

This mod ports The Watcher character from Slay the Spire into Slay the Spire 2, including animations, Wrath/Calm/Divinity VFX/SFX, 83 Watcher cards, 10 colorless cards, associated powers, and 8 unique relics. It's a substantial content addition for players who want the full Watcher experience in the sequel.
✨ Key Features
📊 Pros & Cons
✅ Pros
- Massive content drop: 83 cards and 8 relics means a full character's worth of new strategies.
- Community-backed with 517 endorsements and over 70k downloads—clearly a popular pick.
- Brings the beloved Watcher from the original game into the sequel, complete with visual and audio flair.
⚠️ Cons
- Porting a character from the first game might clash with StS2's balance—expect some cards to feel overtuned or underpowered.
- As a playtest mod, it could be updated frequently, potentially breaking saves or requiring constant updates.
- Compatibility with other gameplay mods is unverified—could conflict with mods that alter card pools or character data.
For Slay the Spire veterans who miss The Watcher and want her full kit in the sequel. Also for players who enjoy experimenting with new cards and relics. Skip if you prefer a vanilla experience or dislike mods that might unbalance the game.
💡 Beginner Tips
- If you're new to modding StS2, check if the game has a mod manager or if you need to place files in the mods folder—most character mods are drop-in.
- Since this is a playtest, keep an eye on the mod page for updates; older versions might not work with the latest game patch.
- Try the Watcher in a few runs to get used to her stance mechanics—Wrath and Calm require careful timing to avoid taking extra damage.
