Traits

By default, Xeros have small, rounded claws. Their claws are shiny and just slightly translucent. They cannot have no claws, or claws of a different shape or size than this without a special mutation.

All Hollow Xeros have much larger claws on their paws to enable efficient burrowing.

The Retractable Claws trait cannot be combined with Digging Claws, as they are too large to retract.

The Savannah Hooves trait can be combined with Digging Claws on either the hands or the feet, not BOTH. They can be added to one set, but Digging Claws must be present on a Hollow Xero in some way.

This trait is exclusive to the Hollow subspecies, all Hollow Xeros have this trait. This trait can only be added to a non-hollow Xero by using a Hollow Beaker on a glitched Xero. However, the Xero will also permanently gain the Glitched rarity.

Some Xeros may have retractable claws; however this is a not a common adaptation. These claws are slightly more pointy than the standard Xero claws, but are otherwise exactly the same when not retracted inside. When not in use, they just show up as simple slits on the paws, sometimes hidden by the fur. 

If a Xero gains the Savannah Hooves trait while having Retractable Claws already present on the Xero, the limbs that turn into hooves will lose retractable claws. However, if the hooves are ever removed on a redesign, the user is always allowed to "bring back" their Retractable Claws on their Xero.
