Where do I paste my code?
Inside the game, not on this site. Forge a class here, copy its import code (it starts with
BTSC.), then in Slay the Spire 2 open the main menu →
Mod Configuration → BlankTheSpire → paste it into the Class code field under
Import a class code and press Import. Restart the game and your class appears at
character select.
Step by step
-
Forge a class on the site and press Copy code. The code starts with
BTSC.and ends with a short hash — copy all of it.
The result view on the site — the import code box and its Copy code button. -
Launch Slay the Spire 2 and open the main menu → Mod Configuration. (the mod must be subscribed on
Steam Workshop first — once)
Main menu — the Mod Configuration entry. -
Choose BlankTheSpire from the list of installed mods on the left.
The mod list — pick BlankTheSpire to open its settings. -
Paste the code into the "Class code" field and press Import. (the field sits under
Import a class code; leave "Class slot" at 0 and the mod picks a free slot for you)
The Class code field with the code pasted and Import ready to press. -
Restart the game — press Restart game (applies changes) on the same screen.
The restart is REQUIRED. The mod will say so right after the import. A newly imported class is only loaded at startup — it will not appear at character select until you fully quit and relaunch the game.
The confirmation after a successful import — restart before you look for the class. -
Start a new run and pick your class from the character select screen.
Character select — your forged class sits alongside the base-game characters.
Troubleshooting
- "Code rejected" / "invalid code". Make sure the whole code was copied — including the
BTSC.prefix at the front and the short hash after the final dot. A code cut off at either end can't be decoded. The Copy code button always copies the whole thing. - The class doesn't appear at character select. You didn't restart. Quit the game completely and relaunch — imported classes only load at startup.
- There's no Mod Configuration entry / the game isn't modded. The mod isn't installed yet — see Get the mod.
- Anything else. Report a bug
on GitHub. If the game crashed, include the lines from
%APPDATA%\SlayTheSpire2\logs\godot.log.
