Moze the Gunner - Borderlands 3 Character Profile
Moze the Gunner - Borderlands 3 Character Profile

Moze is “the Gunner” class in Borderlands 3. With these various skill trees, you can create some very powerful character builds for Moze. Moze has 1 action skill and that is Iron Bear, however, she has many ways to customize her mech. Iron Bear has 2 hardpoints and on those, you can equip various weapons. On the top of each skill tree, you can find a weapon but if you go further down the skill trees you can pick up new weapons to equip. While Moze has a wide range of weapons to choose from she is however limited to how she can augment each weapon. There is only 1 slot per weapon that you can fill up with an augment.

Skill Trees

  • Bottomless Mags
    • Moze’s Bottomless Mags skill tree focuses on shooting and keep shooting. There are a lot of ways to extend the size of your clip and refilling it.
  • Demolition Woman
    • Moze’s Demolition Woman skill tree focuses on doing splash damage by increasing the size and damage output of explosions for both Moze and Iron Bear. There are skills that increase the longevity that Moze can stay alive–prolonging the time she has in Fight For Your Life and increasing the fuel capacity for Iron Bear. A noteworthy perk is that there is a skill that allows Iron Bear to act on its own as a sentry turret.
  • Shield of Retribution
    • Moze’s Shield of Retribution skill tree is a risk and reward tree. There are a lot of skills that keep you in the fight, however, the closer you are to dying the more damage you can do.  So do you like living on the edge?
  • Mother Bear (DLC)
    • The Bear Mother skill tree really wants you to double down on using incendiary weapons as igniting enemies will trigger multiple skills. While some skills trigger when applying a status effect there are a few that trigger when using incendiary weapons. The Capstone skill will cause your Iron Cub not to consume fuel, this will result in it being longer on the battlefield. This has great synergy with an augment that gives you increased damage for every second Iron Cub stays in action. Having multiple weapons will the same element can also stack damage.
