replace hammer shoot by the new mod for loot, especialy with a waframe with petrify & [Ore Gaze] (but you need to format one more or put a rank 0 vigilant supplies)

new mod : metamorphic magazine : +90% magazine & max ammo (magazine 120 -> 218, ammo 840 -> 1596) and 5s petrification after 20 shoot on the same ennemy

you can also swap serration for amalgam serration (-10% dmg for +25% sprint speed)

i have seen build with no [Vital Sense] (compensate by primary [Frostbite]) with [Primed Shred] instead, i have to do test to see the "best" choice
