Hitting at least 3 enemies with an attack, increases your damage by 24-36% for 3 seconds.
4.5-6% Close Range damage on Repeated Hit. Stacks 5 times.
Gain 7-10% Close Damage for 3.5 seconds after killing an enemy at close range, stacking 5 times.
This build was useful for me to manage horde control to acheive the "On Overwatch" penance. Low intensity mission and covering the flank of the party will help avoid any melee attacks.
