Guaranteed Red Crits on this build for those pretty colours on your screen(you do have to aim a bit though)
Replace [Serration] with [Hunter Munitions] and Primary Deadhead for Primary Merciless for that Mumu build.
[Galvanized Scope] can be replaced by [Galvanized Aptitude] if you dont want the hassle, not much difference gameplay wise for me(Forma based on how you build it)
This build is catered towards Tenno that likes those crispy headshots, but dont worry the incarnon form helps out with the thicker arrow as long as you aim for head area.
