Explain this to me...

Look at the picture.

It is clearly labeled as a Furious War Hammer. The Furious happens to be perfect (10% chance to double adrenaline on hit), BUT it has another modifier. That of 5% chance of 10% armor penetration, which is Sundering. Last I checked, you can't have two prefixes (Furious and Sundering) except of SoA axes before they fixed them. If it matters at all, the character was one my brother made a long time ago when GW first started, and he had added one of the modifiers onto to it at that point (I think the Furious part, but I'm not sure). So has this hammer somehow become double hilted/pommel (can't remember which >_<) or something? Because I sure as hell can't figure it out :/.

I also happen to have an Air Staff that appears to have a perfect Sundering mod (10% chance of 10% armor penetration), but does not have Sundering in the name (as in, it is just called Air Staff, not Sundering Air Staff).

umm that looks like a collectors item that already has mods added to it

Alright, thanks for an answer. As I said, it's my brother's character that I picked up, so I just wanted to make sure.

no prob....
