The other build for this weapon, that depend of the combo :
https://overframe.gg/build/110263/paracesis/Slash-Viral-Crit-Status-Combo/

As stance, none of the 3 stances are objectively bad, it is a question of personal preferences.
And they are very different, you should test them.
Especially the combo : aiming+move forward+basic attacks.

Change [Voltaic Strike] to :
[Vicious Frost] if you want Viral instead of Corrosive.
[Virulent Scourge] if you want Toxin instead of Corrosive.
Corrosive is by far the best to kill the greener that have Ferrite Armor (most of them), by ignoring 75% of their armor. It is also good to kill the big infested like the anciens.
Toxin is the best to kill the Corpus, because all Toxin damage bypasse the shield.
Viral is good because the status proc will double the damage taken by the target (exept on shield).

[Gladiator Vice] is the mod to remove if you have a good Riven.
You can use [Quickening] instead of [Gladiator Vice], it is near as good.

The arcane Strike is also very good to have more attack speed.
The arcane [Fury] is very good to have more damage.
With both at max rank, you increase your DPS by more than the double ; and they are very good for any melee build. If you like to play in melee, you should try to have them.

to all the primed/sacrificial mods, if they are rank 8 instead of 10, the endo cost is divide by 4, but they are still good.
most of the mod are rare. a low cost version of this build, in mod en endo, is :

(alternative for the mod that you don't have in this build)
