This is a old topic, not to criticize, my hammy had like 4k life at lvl 90....I find using an act1 merc w/:
Hydra bow faith
Fort
Dream helm
is better than act2
1) No I.M.
2) it shoots cold arrow wich freezes everything
3) it looks cooler than act2 merc

i liked my hammy till it got deleted........
But other than that...........Good job man, gratz very nice. im taking some of these tips for my new hammy next lad
