That part is... still kind of confusing. I barely understand how any of this stuff works. It wasn't a physical thing, not really, but when my eye was affected, it let me perceive its true form. Once I could perceive it, it became a physical entity, that could be killed. Rock salt is effective against a lot of monsters, but so is shooting them, with guns.

Like I said, I don't know how it works. All I know is that once I saw its true form, I understood that it could be killed, and that made it killable.

[The Otherside is a weird place. If Sorawo knew how it worked, she'd write a book about it or something. Nobody understands that crap.]
