ok. I saved some faction invasion general weapon drops on the chance they might be alterable later. Today I remember the old chest stored in the bottom of my keep and spend some time looking for them. I dust some off and try to imbue. Okay. I get message: "This item already possesses special material and cannot be imbued." However, I ve been crafting in my unravel bag and later go to unravel and poof goes my cool weapon made out of mysterious material. I am puzzled. So I grab another invasion weapon and try to unravel and it gives 2 essence. I though you could only unravel plain items and no special materials. Is this broken or is this right?
