Mesa Prime Build

4th Ability — Peacemaker:

"With intense focus, [Mesa] draws her Regulator pistols, shooting down her foes in rapid succession."
Oh we’re making peace alright… pieces out of these Grineer! The strongest ability in the game (this is a lie), the Peacemaker. [Mesa] draws from her wrists exalted revolvers, and she just pulls apart everything… and I mean EVERYTHING. The true BFG if you ask me.

Modded Crit Chance (Topaz, Secondary Outburst on [Regulators], [Primed Pistol Gambit], Hotshot):
25% x (100%+300%+300%+240%+187%)
25% x (1127%)
281.75% Total Crit Chance
