I'm rather surprised that I managed it at level 68, even if it was mostly by abusing knockback spells and Escape walk speed. Since I'm really bored right now, I'll post my setup here. Feel free to comment on the horribleness of my build or whatever; it's my first playthrough since Gavel and first above level 50ish ever. I used a rainbow build - Infinity with T4 fires, Millenium, Kratke, and (for some reason) Bad Wolf. I actually wore Helmet of the Legends during the fight, because my previous helmet was getting a little old... (Shinespark, Level 47), and the raw melee damage helped a lot. Accessories - Morph-Amethyst and Morph-Ruby for the set bonus, particularly the rainbow damages. I used Rockworm, for some reason, and Druid Ring, which I got on my last Dernel lootrun before the fight and used temporarily in place of my everyday ring Glitz. I brought 5 health pots, of which I only used half, and 2 mana pots, which I used up way too early. I also brought a few skill pots (specifically, one each of level 65 Strength and Intelligence), which I got while lootrunning (Dernel is great). My strategy was basically just alternating melee/Arrow Bomb (to deal with the minions) as CoW approached with Arrow Storm to push him back occasionally - this plus the Int pot meant I never actually ran down my mana unless I messed up. I did slip up and get caught a few times without mana, in which case I just spammed health pots until I could Arrow Shield.
