The textures really are from there; at least the wooden staff will definitely fit well and doesn't really look like a magic wand; it's more like a stick for beating people.
There's a picture with such staffs circulating on the internet, but I haven't seen them anywhere. If this isn't just art and they can be extracted from somewhere, that would be ideal.

I searched the internet, and it seems these staffs were made for Dark Messiah on Xbox. It's unlikely that they can be extracted; it's easier to come up with something else.

So, you're saying you haven't seen such a staff in the PC version?!
I've played through Dark Messiah (and even made a Walkthrough), and they aren't in it.

In my opinion, these aren't staffs from Heroes.
They're from some other game
