Well first I perma invulned as Deathknight. I used it and never became vunerable again. This carried over to Dervish.
EDIT:Like 20 min later all my levels got reset....wtf? I got reset to a guest and my permissions for DHero are gone so now I'm just a hero.
If you could please set my levels back I think I had 36 DeathKnight 24 Dervish and 18 Archer.
EDIT2:Now I think the server is just fucked up because I place blocks weird and I keep teleporting back to the top of this block thing.
