Third in my series of MLP girls as D&D adventurers, here we have the lovely Rarity. Of all the designs I've hashed out, I think Rarity's is my favorite; part medieval duchess, part Disney princess, and with just a smidge of southern antebellum. Mostly inspired by her look at the Gala.
Of course, in the rough and tumble life of an adventurer, such a nice dress would surely get ruined-which is why Rarity always makes sure to carry an extra outfit! ([link])
I like to think she keeps a sword hidden in her bustle.
Only one sword? Still, you are right to give Rarity 2 costumes: one practical yet good looking, and one totally stunning! You might have to use the d20 "Book of Erotic Fantasy" to properly stat her if she levels up....
