it wouldn't be the best but it's pretty nice
i would reccomend using v1.08 gloomstrap
or trangs belt
but the best would be a 10%fcr/stat's/hp/mana/resist/fhr crafted belt
10%*shako+35%*storm+30%*shaft
=75%dr
waterwalks would be a good idea
unless you can afford something like..
soulspurs or rune slippers
(if you got those with the high resists, (esp fire/psn/lit) you can put prubys/fal/ko instead of ums in gear

use magefists for fcr/manaregen/fireskill's
merc should only use windforce
if its hel'd or if she is also using lionheart armor
