Combine it with Secondary Dexterity (AND PRIMARY DEXTERITY IF YOU WANT :D 720% DMG for both pistol and primary, while having +15s combo duration, so you don't need naramon)

(At least I think its warframe skills, it doesn't specify to which weapons applies, I tested different weapons and it applies to all primary, secondary and melee)

Very important to use [Pointed Wind], the combos you should do are either spam E standing still (character will move forward) or right click for GUARD and SPAM E , both those combos have the same duration, the same damage, and status apply, so use whatever you like, dont do W+E because it does less dmg and its a different combo, you could do it but you will lose dmg.

We're applying a lot of status with the weeping wounds and the 2 60/60 mods, so [Condition Overload] is better than a primed faction mod (tested)

I run secondary dexterity on my [Laetum] to synergize with this weapon, and its awesome, I get 360% damage with 6 stacks, each stack last for 20s, so its better than deadhead on overtime long damage without having to re-apply the arcane buff, also its less annoying than deadhead because I don't need to land precise headshots to trigger it, just kill some trash mobs.

If you want to try the VIRAL build, its the same as this, just change [Voltaic Strike] for [Vicious Frost], thats it, nothing else. same build and same forma count.

ENJOY! Remember to SPAM E while gliding to throw projectiles, get 3 kills with projectiles (very easy, does a lot of dmg) to get 150% MORE DAMAGE!!!

Evolutions:

2nd: 25% attack speed
3rd: 60% finisher damage
4th: Airborne Melee kill 50% damage 10s stacks x3
5th: Collecting ammo grants 5 melee combo counter (VERY VERY USEFUL)
