The description say:
Casting an empowering rift grants Devour. Damage dealt by you and your allies from within your empowering rift will disrupt combatants.
These legs only work when using a Void subclass, something not specified in the description. Void subclass can already get devour from ability kills, orbs, and picking up a void breach.
Combatants don’t get disrupted unless they are Overload Champs.
Why would anyone ever use this exotic??

Seriously. I get that it came out when devour was void only, but that's gone in an age where we have buried bloodline.
