I feel the majority of the things I gather from mobs, I vendor. I have yet to make the mistake of NPCing something of value or equipment that I'm currently using but I'd like a little insurance. Mind you, I haven't touched the game in a month and it escapes me whether there is an "Are you sure?" window popping up.. but even so, some steps, I feel, need to be skipped/done away with as the majority of the game's adventure is spent through windows that lead to other windows.

I think I detracted from the point.. Buyback Feature.
