7.5-15% Weak Spot Damage. Weakspot Kills also ignore Enemy Hit Mass.
3.5-5% Strength for 3.5s on Hit. Stacks 5 times.
14-20% Strength for 5s when every pellet in a shot hits the same enemy.
Up to 14-20% Damage on Hit (Staggered Enemy), scaling with Stagger.
kraks for krakkin, axe lights for meat (aim for the head) heavies for armor, shotgun is godly and can deal with just about everything even mauler in a pinch, you can flinch reapers with it, etc. bind your quickswitch to something easy as one kill=1 shell if you want to farm up your own ammo.
