The red and white face mask sold in the clothing shop in the Dairein settlement, the description doesn't make it clear if it should be able to be worn by arials. Like the other two face items I mentioned, it won't fit an arial face.
As expected, I just like to hope I've found one that ought to but got missed.
Working the bug board is important, but not necessarily very fun. I'm happy to do it, but I'm not here to check wild guesses. Neither one of those items said anything about being made for an arial. Please do not post random facewear- looking up the item, tracking down the area's author (if possible), and handling the web admin portion is often 5-10 minutes of my time at the shortest. There's a few dozen bugs in the queue at present, and there's better fish to fry.
We check every bug and trace every angle. Please don't take advantage of that.
