My group also has the black dragon mask. They've mostly used it to bluff their way into places. It's not been tremendously game-changing IMHO.Out of interest, why do you say this? I just ran my group through Greenest in Flames, so I'm a fair way away, but I know that Steve Winter said he wanted to let the players get the masks, while WotC were resistant to that idea.
