A personal headworld wiki
While your typical Crystali design can be pretty diverse, they can also come with some extra fancy traits. These are all loose descriptions and can be interpreted in many ways. A crystali may have many fun traits, but (I think) anything more than 1 or 2 of these would make a Crystali stand out like a sore thumb.
Orphan Sources - Extra crystals that are not part of the 3 base clusters.
Vertebrate Tail - Having a tail. This gene is very undesirable since it seems to remove a lot of a Crystali's ability to use magic. Possibly due to the flow of magic through their bodies being interrupted by having a nonexistent or highly unusual tail cluster.
Anomaly - Having hoofs instead of paws, or having some scales on certain parts of the body. This trait encompasses pretty much any mutation that changes their base physiology.
Floating Sources - floating crystals
Chroma - Having 2 drastically opposing elements, or an element so complex that their magic mist appears to be significantly multicolored.
Wings - Winged crystali are incredibly rare. This gene has largely stayed within families with royal blood. The wings are usually just an excess of magic venting through an extra cluster.
