Each Catalyst type has a set of visual base traits. When consumed, a Kodamara’s traits will be a randomly generated unique combination depending on the Catalyst and Mara type.
A Mara’s tier has no impact on the visual traits assigned to a Kodamara. Nevertheless, a Mara tier and role will have a direct impact on a Kodamara’s in-game stats and skills.
