Tell me where to get the monster shell? (The Witcher 3: Wild Hunt)

Glavoglaz.

I killed the head-eye and it didn’t fall out of him, but if it’s not difficult, then tell me where he forgot.

Random places, like the same wolves.
The exact place can only be found in some kind of witcher order.

I remember myself looking for such components for an hour, but it turned out that they are obtained by parsing materials from blacksmiths. The mechanics are rather strange, of course, if not idiotic, but as it is, so it is.

thanks, i'll keep looking

figured out, you disassemble the skin of a basilisk and get a shell
