Gonna have to call bullshit on Ferrins post, no way in hell he has enough aura to do all that. you need to either nerf the semblance significantly, or massively increase the amount of aura it uses.

1) His aura is rather strong. Remember, he came from 3rd generation hunters, He was trained from a very young age.  
2) I implied that he took breaks, I just didn't mention that part directly because it would mess with the flow.
3) It was rather difficult for him, I was/will mention that in later posts.
4) Something like that isn't unusual, remember that the canon test where they took down the two massive Grim happened [i]before[/i] they started at Beacon. So having that much ability is not unusual.
5)Most of the limits of any aura is not actual strength but how creatively they use it. His requires brain power, which he has.
6)His aura is very dangerous one slip up (and I will make him slip) and he could badly injure himself.
