Seeing comments about how humorously unphysical the arrow seems, at least one can say that it is “magic”, but still ridiculous anyway.
Talking about “realism”…
How our MC is unharmed from a cannonball impact to the golem directly behind him is I would say even more unphysical. He can hear just fine and his ears wasn’t ringing after an explosion occurred very close to him.
Also, somehow no shrapnels touched him considering the cannonball seemed to explode on impact nearby (or shrapnel from the golem if the cannonball had gone through perfectly).
I’ll just think of it as shrapnels have not been implemented on this patch kind of thing.
