EDIT: For anyone coming across this thread late, the mod is now hosted at: https://triplis.github.io/mods/sorcerer.html And updates are found there. This will probably get moved to the Modding...
I downloaded your mod, opened it, put in the mods folder, all that mod stuff, but the option isn't showing up on the clay. From the comment above I don't believe it's anything I did, but just in case, did I miss something?
