I'm asking myself the same question and I didn't make quantifying statements about Vaughtar for the same reason. I'd feel fine with the idea of specifying more precisely together - if you want ofc.

Additionally, one thing I can offer to everyone who feels uncomfortable with the current situation is to moderately shift Vaughtars focus. In fact, the character is based on a concept I used a long time ago (in another forum and a RP that never really took off) and there is an aspect I haven't introduced in Vaughtars first sketch since I was afraid of overpowering him. It would be some kind of nonlethal, delayed, but pretty insidious dampening magic.

All of these considerations do, ofc, daringly assume that the base concept itself will be able to receive the GM's "OK"-stamp one day ;)
