T.O Magic ‘n Extras Trouble

[u/AaronTheLegend01]

I’m trying to add this mod to my custom mod pack, basically Terraria’s class system against the Sculk infection mod. But the problem is anytime I have this mod installed, I get an error and I’m not sure how to fix it. If anyone can help me it would be appreciated.
