I picked hammer. Yet it is a coin flip for me depending what other set I am rocking with. Ice is mint for never running out of ammo. However, hammer can be unlimited as long as you constant critical shot on bosses. Damage: full IB on atheon 14980 crit Hammer (80%) atheon 19980 crit Now those are rough guess off of the last run. Ib full upgrade 14k hammer not full 19k non stop shoots. I got 9 in before reload and run. Hope it helps.
