This build benefits from Multishot rivens more than anything. Multishot increases your slash proc consistency, [Double Tap] stacks, and the rate you cap an enemy out on Viral proc debuffs. If you want to use a riven with this weapon, try to get one with Multishot.

Vigialnte Supplies is added as an exilus mod, but it's unnecasary as this weapon doesn't struggle for ammo. But it is a very slight damage increase so forma for it if you want.
