Whatever this build doesn’t one shot is done in by a second shot. Very few NPC’s are exceptions requiring a third shot. Skulls glove and MMR damage give you 28% AWD. Pop pulse for Barret’s 5% damage bonus to take your AWD to 33% not to mention pulses own multiplier to damage and the increase in CHC/CHD for that multiplier. It also doesn’t hurt to know where enemies are. Booster shot can be used to further increase damage against heavies and Named NPCs or as a heal.
