Cosmetic things:
- Exclusive hair and beard styles (scales for argonians), hair colors and makeup/facepaints/bodypaints/scars. Buying unlocks permanently for whole account. (Will of course require that the addition of a make-over option in game too. One that costs gold to use)
- Face masks, headbands and crown/tiara crafting recipes. Goes in headslot. Basically a helmet that doesn't mess with your hair. Has the same stats as normal headgear. Research would also automatically overlap.
- Ghost horse mount in time for Halloween.
