Poxx = Shadowknight.
Axe of the Orcslayer has a type 4 augment slot. Claw of the Arbiter is in slot 8. This weapon includes SHD as a class that may use.
Sharp Froglok Eye is a type 4 augment slot for 2handers and includes SHD as classes that may use.
When I try and insert the Sharp Floglok Eye into the empty slot 4 on the Axe of the Orcslayer, I receive the message:
"Error: Classes do not match"
