im running an orb/hydra sorc, and just finally got past hell andi, i have a boneweave treachery armor for merc, with 500 defense and he is currently using a low level poleaxe insight.
i have a colossus voulge that i can socket and put another insight into, should i do that or look at any other runewords or uniques for him. also which helm is best either way?

make the cv insight

with treach armoru can go for any helm u got that has ll, tal helm, andy face vampire gaze, or 3soc 8ll diadem.

u could go for an expensive build like coh armor, infi and cure helm i guess, but not worth it imo

this.

or RW Bulwark is also handy.
