Doesn't really matter how op someone else is If somebody swings a guillotine mallet at him and goes to lob his head, but he survives it and kills them with a poke of his axe by redirecting all damage, heals and the fight is over there and then. Stamina doesn't really come into play when you're immortal, can reflect anything, can reflect damage from OTHER things then have no negatives aside from 'whoo, boy. i'm pooped now.' Most people are pooped after they annihilate something.

I'll take away the flinch factor, I guess. But, I mean, that'll work on one person. If it's a group fight and you see your friend Omega Death a guy and he gets up to redirect that, there's a chance you aren't gonna want to avenge his death immediately. He doesn't have the speed, in anything really, to catch anyone, he has a swing of death if you decide to waste whatever nuke you got, but that's not gonna come in like a proverbial wrecking ball that can break the sound barrier. It's going to take one idiot to go up and attempt to shoot a point-blank death laser for everyone else to learn that attacking him means empowering his own attacks. If you aren't faster than he is, then it might be wise to just attempt to block and stall for as long as possible.

If you hit someone and it doesn't hurt them, chances are you aren't going to keep hitting them, you're going to wait and see if they reveal a stark weakness. His being that he's slower than the average hunter and this drains his aura incredibly fast and he has no control over it. Once it's on, it's on until its drained every bit of stamina, energy, and aura from his body and when it's done, it leaves him pretty much dead for a day. I mean, that's a huge ass weakness, if you ask me. If anything, he's a designated Grimm killer. If someone goes up against him and it's a 1-on-1 and the person is smart enough to discern his ability, then he's going to lose that battle indefinitely.

But, I honestly can make it an activated semblance that has a one time use until his aura has completely refreshed, which is going to take at the very least a day, but most likely more. It's like adrenaline. And it's not, "Oh, I'm pooped," it's more like, "I feel like I'm about to die, so I'm not going to move from this spot for as long as is necessary to recover." If someone prolongs a fight with him, and with the majority of the freshman students who are relatively fast in reflexes and their feat that's a shit ton of people, then they're free to walk up after he collapses to then guillotine mallet his face then. It's not perpetual, it's until every bit of his aura runs out, so he's immortal for a duration and when it ends, he might as well have dug his own grave during the whole fight.
