Go to this Mesa build or this build will make no sense: https://overframe.gg/build/673949/mesa-prime/equipmentless-mesa-red-crit-status-hybrid-build/

Also some how does 1m damage full bore...

MATH!

math for mesa + regulator:

25% Base Crit Chance, multiplied by:

• 5 Tauforged Topaz Archon Shards (75% crit chance each)
• Primed Pistol Gambit (187% crit chance)

Plus flat crit chance bonuses:

• Arcane Avenger (45% flat crit chance)

= 210.5% crit chance.

(25 x (1 + (1.87 + (5 x 0.75)))) + 45 = 210.5% crit chance

3x Base Crit Damage, multiplied by:

• Only Primed Target Cracker (110% Crit Damage)

Yellow Crit:
(1 + 1 x ((3 x (1 + 1.1)) - 1)) = 6.3x Crit Multiplier

Orange Crit:
(1 + 2 x ((3 x (1 + 1.1)) - 1)) = 11.6x Crit Multiplier

Red Crit:
(1 + 3 x ((3 x (1 + 1.1)) - 1)) = 16.9x Crit Multiplier

And that's all, Enjoy.

There's some more math I could have done but at this point I am getting too lazy.
Suggestions in the comments as always.
