Unholy Jolly

I have this aura effect on my main character but I don't even have a paladin in my party. I tried to rest in a tavern, tried to rest using food with bonus and no bonus, tried to hire a paladin to switch the same aura and then switch it off - nothing helped. Does anybody know how to fix this? Save file: https://yadi.sk/d/gDtNfb1S3WbYWh
