Traits are special features that a character may have! They come in different rarities and can be earned by participating in site events and activities to then buy the corresponding trait item. You can then submit a MYO with said trait item, or send a design update request with one if you'd like to add a trait to an existing character. Trait items can be found in shops, so you may want to go window shopping...
Sparkling (Rare) Masterlist Examples
These individuals shine so bright that they emanate sparkles or stars that surround them like an aura. The sparkles can be any shape or color.
NOTE: This trait only affects the characters surroundings, and cannot turn a limb into a different material!
IMPORTANT: You are free to add sparkle/shine to any artwork as a stylistical feature, this only concerns a very extreme sparkle effect that would be noticable in their world, and has taken on an almsot tangible form (similar to snowflakes floating).
