The master trainer for Enchant, unlike his fellow Daedra worshiper Erundil nearby (who irritatingly is the only one you have an incentive to kill), will attack you on sight. I couldn't find any mod that did nothing more than make him unaggressive, so I made one myself. Not much to it -- I just lowered his fight value to 30. Do whatever you want with this.

Just put the esp into your Data Files and enable.
