Best Gear For Harlowe Gravitar Build

The best way to get a high fire rate is using the Submachine Gun like State Boory. These generally just have the fastest fire rate of weapons in the game, but they can also spawn with an underbarrel attachment. This gives you an alternate mode with a significant fire rate increase. Fast fire rate means faster application of Neutron Capture because it’s a flat damage bonus. Super high fire rate SMG is your bread and butter.
Maliwan Shotguns can roll with the beam tosser underbarrrel that does a ton of damage. The other equipment slots on the Repkit, the main modifier that you want is Enrage, at least for pure damage. This increases your damage done and your damage taken for a few seconds after you use Repkit. The Throwing Grenade for this build increases your damage sources as much as possible. The best way to do that is with Jacob’s throwing knives, specifically with the damage Amp payload modifier.
The 15% bonus damage to enemies for 5 seconds after you hit them with the knife. For your shield, nothing is overly important for damage-dealing purposes. Use it to focus more than anything on survival. Some shields do give you a fire rate when your shields run out or increased damage to shots.
