Anyone tried 5 boxing sethekk halls? Well.. i tried today.. but the last boss was hell of a shit.. it was juz too hard to kill.. with it's random teleport and casting arcane blast... it kills my 2x shaman, 2x mage and leave my warrior with less than 1/4 health.. was wipe 3 times before i finally gave up..

Anyone tried before and has some way to kill this guy?
