@Natsume HonnajiHow does going fast lessen the impact? And I don't see how using his metal gauntlet will help in this situation, since he's smacking into the wall. Why don't you have him be a bit more tactical and aware if his surroundings and, I don't know, try just walking through it. He must notice that people are phasing out of it, and that aside, I don't quite understand what is possessing him to decide that the best way to get in the done is to ram his way through with his un reinforced, human body. I hear taking a beating, but in this situation, you are the fly, the done is the wind shield, and the only reason why it won't quite end like that is because A) hopefully not going that fast, and B)You're phasing through almost immediately afterwards.
Sorry for the rant, but that had been bothering me for a while. It's just . . . such a bad way to handle this situation,, and one that could get your guy killed.
