Work in progress

High duration/strength build to optimize [Mesa]'s 2 (damage buff), 3 (tankiness, 95% bullet damage reduction) and 4 (pewpew, kill everything).

[Regulators] build here.

Optimization and variation:

• Replace Power Drift with Mesa's Waltz if you prefer the additional mobility/quality of life. I usually activate Peacemaker midair, do a quick 360 sweep and toggle it off before landing. No Waltz required.
• [Mesa]'s damage output benefits more from [Growing Power] or [Corrosive Projection] (Forma required). [Pistol Amp] does NOT increase her total damage by 27%. This value is merely additive, it will simply be added to your damage mods (Hornet Strike).
• Augur Message/Constitution can be easily replaced by Adaptation for extra tankiness.
• Wanna squeeze in Umbral Vitality? Forma the Exilus slot, use a Power Drift rank 4, and add a Naramon polarity instead of Vazarin (Vitality slot).
• Depending on your ability usage, you might not need a Primed or regular Flow in your build. Feel free to experiment.
• Ability range can be a strong tool to better utilize all effects of your 2nd and 3rd ability.

Arcanes

• Personal preference. Use whatever you like/own.
• Guardian or Grace increase survivability.
• Velocity to increase damage output, highly recommended!
