I can't figure out how to make a NPC use high level spells. If I give the NPC thunderbolt or incinerate as example they do not use the spells, instead they start using their fists. If I add a spell through the console to the NPC that is low rank like flames or firebolt, they start using them. Other NPCs I created with low level spells works well. Anyone know why? Already tried changing class, combat style, pumping more magicka(doesn't matter I think?)... tried adding a staff but the AI only uses it when they don't have any spells.

EDIT: Nvm, apparently any changes I did in CK did not apply to the game ... did a clean save and restarted and now it works. Very strange though, usually any changes I make shows up in game without having to do anything different.
