well i have a lvl 97 pally and when i ha dit in my inventory and died cause i tried just to see i still had the same amount oof exp so jedimaster idk what lvl you are but it happened to me i was missing this much exp | | and after i died im still missing this much exp | | so i would say yes it prevents you from loosing exp, im not saying it dosent do nothing else but it wont let you loose exp. and you probably all know that at lvl 97 when you die you usually loose like this much exp |.......... |
