This is a full duration build. If you want to use it as I built it, you should have an EV Trinity in your team, otherwise you should swap the Intensify to Fleeting Expertise for the lower efficiency. This build made for Excavation missions, like Core farming.
You can do a Survival camp Vauban too, it is not that hard, you have to exchange two Mods. First, the Augment Mod Repelling Bastille to Perpetual Vortex, and the Intensify to Overextended for the higher range. In this case EV Trinity is really needed.
5 forma, no primed mods setup. due to kohmak’s unique spool up, the least amount of damage per magazine is 110k (2*80*692) and the maximum 553k (10*80*692), + the innate 1m punch through, make for a viable crowd control weapon. For corpus, switch out the third elemental mod for an expel corpus, and for grineer, move around the second, third and fourth mod around to get viral + radiation
This is the build that I use which has all of the essential mods. Corrosive damage is made to enhance damage against armored foes during uncoordinated public matches. The Primed Heated Charge is used due to its MASSIVE damage bonus and the rest of the mods are self explanatory. Don’t be fooled by the builds which tote doing higher damage per second. Damage per second at the cost of damage per shot leads to a sharp decline in ammo economy. What good is “80K DPS BOLOR PRIME BEST DPS” when you run out of bullets in 2 seonds?
