I think this [Xoris] build has some real potential.
In order to use this build you need to get your combo counter maxed out ASAP. The crit & status chance you will get form a x12 combo multiplier is pretty insane - you're effectively at 100% status chance and 150% crit. With [Sacrificial Steel] you're sitting at 140% (200% with [True Steel]). Combined with the explosion from Volatile QR and damage multiplier from [Power Throw] you'll be proccing AoE Corrosive damage like nobody's business, while dealing insane damage. Never explode your [Xoris] using the heavy attack button with this build, you'll lose a crapton of DPS and status utility.
The reason I'm not using [Condition Overload] is cause the VQR explosion doesn't have 100% status chance like heavy attack explosions do, and you're only applying one status type. Therefore I think it's more beneficial to stack Corrosive procs.
Unseen downsides to this weapon are its slow flight speed and range. Unseen advantages include its blast radius which is the largest out of any [Glaive].
