this build is very strong on high level, we cant really upgrade it, exept for the riven.

-> THIS BOW HAVE AN INNATE AMMO MUTATION
so please dont use this mod. the best exilus is probably [Ammo Drum], but terminal velocity is also very popular. i prefer the ammos, with a carrier you have 14 shots, and i never need more.

hunter munition-> you hit huge damages, with 1.9 multishot, so this mod is obviously amazing. around 1/2 chances to proc.

[Primed Cryo Rounds] is just the best way to deal damages, but i dont use it. my build have [Infected Clip] because i like to change for corrosive without [Hunter Munitions], and the polarity is just too difficult to use when you change the mod.

If you dont have any riven, you need [Heavy Caliber], or faction mods if you like them.

finally, [Vile Acceleration] is a must have. you can run [Speed Trigger] but you only get 120k dmg instead of 115k, and you can feel the difference .

you can try everything, [Hammer Shot], vigilante armements, everything you want, this build is the best ( with a riven, [Hunter Munitions] and [Speed Trigger]) without taking into account the faction resistances.

i like to use the vigilante set on my companion weapons (20% to increase crits by 100%), with that you can sometimes red crit, if you get the 25% of orange crit and the 20% in the same shot
