What active fighting powers do you think a witch of void will have in light of what we see Roxy doing in the fight vs the condesce

Forget Roxy’s powers, they’re very specific to the Rogue of Void, and specifically, to Roxy’s take on the Rogue of Void Aspect. Rose actually acts like a Witch of Void for a rather substantial amount of time when she goes Grimdark, but also the ability to Manipulate the Lack of things and Emptiness by itself is a terrifying power- Beyond being able to obscure things or get Grimdarky Powers, a Witch of Void might straight up tear people apart by ‘Changing the amount of Void within someone’, as well as possibly replenishing any source of anything by ‘changing how deVoid it is’? Manipulation of Lack can be an intense power.
