The difference is that rinic's range of effectiveness lies only in combat, he's useless in everything else. He gets more spells per day as he becomes stronger, and once he's used them up, he can't use them anymore. He's only ever going to get one more spell and that'll be it. I've halved the number of spells per day he got, made arcane crush easy enough to dodge, and he only has a sword with assistance in persuasion that can deliver a minor shock with the right spell. His guantlets, only heal scratches after 20 minutes. Although, if you'd like me too, I'll get rid of 3 spells for later use you can choose.
