Ok pplz u need to be lvl 60+ for this ****.
In shattrath go near A'dal and take the Quest from Khadgar that is standing right next to him. He will summon an elemental that's supposed to show you around but instead the summoned elemental becomes your "guardian". He deals around 45-50 dmg. Now just abandon the quest, and accept it again.. now u hav 2 guardians.. repeat until u get tired. This is good xploit for blizzlike servers cause u can run around with those elementals grining mobs like a mfr... and of course they can pwn other players. I've got 20 yesterday and checked their dmg in Terrokar... they dmg sums around 1.5-2k dmg per hit(they crit often)...
If u use portal, HS, flight master or get too far away(with ur mount) they will disappear.
It works on mangos, haven't tried it elsewhere.
Don't get caught
