Rufinus trapped by his own lightning
Rufinus is a Colovian drunkard found in Southpoint. Along with the majority of the populace, he has been cursed by Sheogorath. This has driven him insane and cursed him with powerful lightning powers. He is responsible for the random lightning strikes that block entrance to Daraneth's laboratory. You are given the option to either kill him, or talk him out of his attacks using Persuasive Will. If you calm him down, he will later be encountered in the Cathedral of the Golden Path, where he will help you fight your way through the dungeon. He attacks with his fists, which deals shock damage to enemies.
