By other beings you mean other than Grimm right? But how would that direct a Grimm to attack Ren when he's concealed? Maybe I should've said "completely undetectable" if Grimm really do just rely on negativity sensors when attacking. Because if so, I would imagine Ren can pull off a quick kill, at least with one Grimm. How much aura and time do you think will be required?

So here's what I envision: Say Ren was about 2-3 meters away from the Nuckalavee. He uses his Semblance, Nuck can't find him. In 3-5 seconds (10 tops) with his Semblance active, can't Ren just run up to the Grimm and slash it to death with his blades? (I mean, not like Grimm have any aura-like defenses to prevent such penetrations, right?) How much aura should that cost him?
