i've been aoe grinding in Utgarde keep for a while now on my mage and thought id post it.
youl need a mage around lvl 73-75 and you must be speced frost with imp blizzard.
start by pulling the first two mobs and aoe grind them down using frost nova and blizzard. repeat for other packs of mobs.
3-5 mobs per group with 37500hp each
loot/exp:
drops around 50s and you get lots of frostweave
im getting 7k exp per mob rested at level 75.
didnt have time to go into detail so meh :yuck:
