I haven't been able to do any magic since the 1 time I did it. That was a while ago and I can't figure it out. I tried to research it, but is it really only through human sacrifice (r/♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥)?

Also, I went down the arcane line for a while and possibly around the time I did the magic, I no longer could unlock anything in arcane. I have 16 magic points to spend (immortal character) but I already went to true witch (I switched to witch because I couldn't go down arcane anymore) and got all of the warlock except the final one (I picked witch).

Overall, I can't do any magic and I can't spend magic skill points to get Caster and The Ritual before the last perk Mage in the arcane line.
