I’ll throw some ideas.
Moze’s currently equipped weapon gains bonus magazine size and other bonus for every piece of equipped gear that has a matching manufacturer.
Magazine Size: 10% per matched gear.
COV: -20% Heat per Shot per matched gear.
Dahl: +5% Recoil Reduction?? per matched gear.
Hyperion: +5% Handling?? per matched gear.
Jakobs: +5% Critical Damage per matched gear.
Maliwan: Adds 20% of the current weapon’s damage as Elemental Damage per matched gear.
Tediore: +15% Reload Speed per matched gear.
Torgue: 3% Splash damage per matched gear.
Vladof: +3% Fire Rate per matched gear.
Moze gain a chance to ignore damage that would otherwise kill her. In addition to not taking damage from the attack Moze will Regenerate 60% of her Max Shield.
F.F chance: 30-40%
(Like Axton’s Grit)
Im not sure about this one, maybe change it to A.S cooldown Time instead of A.S cooldown rate. 0.1 second per skill point (with an internal cooldown of 0.7 secs)
When Moze deals Splash Damage, her Action Skill Cooldown Time is decreased.
A.S Cooldown Time reduction: 0.5 seconds
Moze gains increased grenade damage for every grenade missing from her grenade supply, she also gets max grenade capacity.
Grenade capacity: +3
Grenade damage: up to +70% or +100%
(Like Click Click but based on grenade count or "Doppelganger’ skill Just Compensation)
Another one that is not in your list, Desperate Measures:
When Moze health is below 80% she deals increased weapon damage against enemies above 80% health, if Moze’ health is below 50% the bonus is tripled.
Weapon damage: 12%
