The purpose of white rings, is for all characters to be immune to sorceress's attacks. Which mean, if so your friend has a 95 godly sorce, then the only thing she can do to a barb, is heal him. A sorceress, could never do 10max dmg with a character that has 1/2 white rings, especially a barbarian. The only way for a sorce to kill 1 (or) all characters, is for the sorce to get a high powered, high leveled merc, and that could do great dmg while sorce is teleporting around.
