Well first let's set aside the fact that the wounds are physical, not magical in nature. The only wounds he had received upon entering were a "large gash on his shoulder" and several superficial wounds, plus torn clothing and armor. Assuming the marks are torn rather than sliced, as with a sharp sword, that's still not enough info to rule out anything other than a large beast (or a vicious humanoid) but that still leaves pretty much any possibility that isn't a guy with a sword.

I do not know the size of the dragon and whether its talons are inherently magical, or the manner in which metal armour (ignoring the softness of silver) was torn into, hence my reason for asking.
