[Azothane] build for that Sephirott vibes.
This is a heavy crit based weapon, capable of doing huge amounts of red and orange crits, with some good range and okay attack speed and status chance, saddly the stance sucks...
1) [Blood Rush], [Organ Shatter] and [Gladiator Might] helps to improve even more the crits capability of this weapon.
2) [Condition Overload], [Weeping Wounds], [Primed Fever Strike] and [North Wind] are here just for damage.
3) [Berserker Fury] is an essential in this build, you could switch for [Primed Fury], but i do not recomend.

Where is [Quickening]????? I know... its not a fast weapon... but honestly it hits fine and, at least for me, dont need more attack speed. Disagree? Switch [Gladiator Might] for [Quickening] or [Gladiator Vice] (for not loosing crit chance) and you good to go.

Where is [Primed Reach]? Honestly the range of this weapon is already good, so a prefer to prioritize attack speed or raw damage, if you want to, switch for [North Wind] and use a secondary for viral procs.

Is it not worth it using [Sacrificial Steel]? Its a very expensive mod and umbra formas are quite rare to get. I dont think it worth it, also, there are other stuff that we need to fix in this weapon that is more necessary than more critical chance.

What about its "passive"? Meh, quite situational but can help for you in building combo.

Got a riven? Try something for improving attack speed and crit damage/chance.

Saddly this build cant fix the trash stance.... Love for two handed nikanas...

PLAY WELL TENNO
