Traits

Metalic Markings allows a Biovent to show metal markings including gold, silver, bronze, steel, glitter, so on.

It does not create any sort of growth or distortion. Additional traits are required for creating things such as metal spikes.
It cannot be added into the infection nor replace limbs to have them made of metal or glitter. That is reserved for the Metalic Infection.

It can be added to horns and the spikes mutation for them to be made of metal or glitter sparkles.
