Hello,
I just ran curse of the sky on EE, and Eaga wasn't breaking the DR there, of neither devils or abishai. It wasn't slotted.

As it says, its metalline and righteous. But it doesnt go through devils silver + good DR? Howcome?
Is it possible the adamantine property found on it (why the hell is adamantine there if it's already metalline) is somehow overwriting metalline effect? A bug?
On a side note, it did break the DR of the.....white lion things, which means the it does break good dr.
