We recommend Shotguns and Fusions, but it’s up to you. Shotguns, Fusions, SMGs, and Sidearms all benefit from the Heavy Handed mod. Weapons with Wellspring are fantastic for this build, allowing you to spam Rifts and other abilities with ease. This build isn’t viable for hard endgame content, but the sheer fun you can have with this build more than makes up for it.
If played properly, you can expect infinite abilities, constant Supers, a near-permanent 25% damage increase, and infinite Shotgun ammo. To complement these explosive Rifts, this build also takes advantage of a few Charged with Light mods that center around aggressive play. As ridiculous as that sounds, the Shadebinder’s Frostpulse Aspect can turn your Warlock’s Rifts into group-clearing explosives when paired with Vesper of Radius, an Exotic chest piece that most Warlock mains have forgotten about. Carve through waves of PvE enemies with nothing more than your Rift.
