Here is a general note when doing nithalok with this build:tele near group, walk away from merc so that he draws in the monsters, now target Nithalok, and fire wall him, if he is immune to Fire, then Blizzard him, if he is immune to Both, draw monsters out one way by tele'ing merc with you, kill them and approach from the other side and tele in, static and let the merc slaughter him.
