Just a couple I've come across on a couple of my alts, sorry if this is a repost.
Dwarf:- Stoneform
Mage:- Iceblock
Lock:- Lifetap/Hellfire until dead
Paladin:- BoP (Need confirmation)
Anyone:- Duel someone and lose. Don't forget to do /forfeit when you get 'turned'.
Of course, these only work once you have the 10 minute debuff..
