Re: Best weapon for merc's Infinity?
I'd say Great Poleaxe as with 20 IAS more (andy's visage) he'll attack at 7 fpa.
That or a Giant Thresher (22 IAS for 6.5 fpa). (my fav)
edit: or Cryptic Axe as with 35 IAS (andy's visage plus IAS jewel) it also reaches 7 fpa.
Wouldn't really look in any of the others.
