​

Sentient Hood

A living hood that can resemble a furhood when down, and may function differently depending on the Cinna.

All sentient hoods are furry unless another rare trait allows for exotic skin types, unusual bodies, etc. One set of eyes and ears are complimentary.

​The hood is an extension of the Cinna itself, so the same rules apply. In official Masterlist artwork, the Cinna’s face must be visible somewhere on the reference.

Cerberus

A trait in which a Cinna is allowed three or more heads. If the heads are functional and belong to one entity, it is a Cerberus.

These heads may or may not be attached to the body, as in some cases, a design simply featuring more that one head may not count as Cerberus. 

To use Chimera, this restricted trait must also be in use.

Chimera

A trait that requires the use of Cerberus or Double Head, it allows for a Cinna to have two different Wild face rare traits.
