Possible Arts and restrictions:
The DoAs can be from a range of anything that suggests role-playing, without needing to break the game balance.

Updated Actions & Traits Menu : 12 DoA sub-classes mockup. Skills from DOTA.

Here are 12 example categories show in the image above:
  • Dancer
  • Demon (e.g. Werewolf, Vampire)
  • Musician (e.g. Songstress)
  • Scribe (e.g. Artist, Writer)
  • Aristocrat (e.g. Regal/Royal)
  • Tracker (e.g. Hunter)
  • Fortune Teller
  • Tradesman
  • Butler (e.g. Maid)
  • Thief
  • Student
  • Priest (e.g. Shrine Maiden)
So by completing the Vampire quests, the Vampire rewards will appear in the Demon Arts section.
The mockup shows how the player can mix up to 5 different earned Apparel Arts to use at once. Vampire? Dancer? Why not parts from both?
