No one is entirely sure why quigar skulls can look so varied. Perhaps it is a testament to their connection with the earth?

Your quigar’s skull face becomes like that of a real animal, one not resembling ungulates. As this is such a broad trait, this will have to be overlooked on a case by case basis. There are some guidelines however:

• You can include horns of your allowed rarities or make your own type, but they can’t imitate innate, divine, quest, or event traits unless you have a trait item of that rarity.
  • If a special trait is made that is similar to your character’s horn type, you will not be asked to change it retroactively. 
• You can use this skull type to create weird combinations of animal traits, such as a wolf skull with flat teeth.
• You can pick skulls that resemble real life animals, or even pick the skull of a bird or reptile or cetacean (normally not allowed)
• Living modifier plus this skull can theoretically make a fleshy version of whatever creature's skull you have chosen.
• These skulls are exempt from tooth, horn, and ear rarity. If you have this skull, you may pick whichever ear/horn/tooth rarity you wish, provided it's not a special rarity or unusual rarity.

ALLOWED:

• Real animal skulls
• Skulls of animals not under ungulata
• Cetacean skulls are allowed now.

NOT ALLOWED:

• Fantastical animal skulls
• Strange, warped anatomy
• Skulls of other merlotverse species.
• Human skulls.

If you're unsure if your idea is valid, feel free to ask.
