Nightmare was surely not the type of Tank that would just break through. He was literally one of the biggest nightmares of the wolves on the battlefield at that time...
And maybe that's just why his name is Nightmare.
There were quite a lot of wolves on his side, even then, but using his Tank skills as an advantage, it was understandable that he would be able to keep off more of the wolves better than his comrades.
Nightmare had a weapon that looked like a shield. Truly, it was a shield, but the kind that had an offensive installation in it.
The front of the shield had what looked like strong long blades on it. Ones that were able to pierce through the skull of a monster without stress when struck.
Nightmare made sure that he was making very good use of it, as the monsters that tried attacking fell victim to his strengthened strikes.
With the blue wall shielding him, he was already causing a lot of headaches for the wolves.
