A few of these have already been covered, but I would like to reiterate the need for them and add some new suggestions of my own:
- Deer antlers (like Woodsman or Tuatha) for standard heads and helmets
- Snake lower bodies like Talons
- Dress thing like Sorceress Serene
- goat/deer tail
- tintable hairy animal legs and feet (we currently only have flesh-colored hooves)
- old faces that don't look evil (they currently all look like emperor Palpatine. To be specific, I want Irish actor David Kelly, rest in peace)
- tabards (like knights wear, could be filed as a jacket?)
- a frog animal head
I think that costume pieces that AVs, the Vindicators, etc. have that make them unique from everyone else should not be offered to us - just some basic elements from their costumes. I think that they should have costume parts that are unique to them, as it helps set them apart and makes them "special".
