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...
Horned (Rare) Masterlist Examples
It just so happens that some beastlings grow horns. Though no one really knows why and when it does!
Whispy Whiskers (Uncommon) Masterlist Examples
Sometimes, the whiskers of a Vulpel will grow longer than usual, giving them a floaty more regal look.
Irregular Third Eye (Uncommon) Masterlist Examples
While usually round or oval in shape, sometimes a Felespio's third eye can take on more complex shapes.
Elaborate Crown (Uncommon) Masterlist Examples
A Lupircus may develop a crown that is more elaborate in shape, material and size, sometimes even reaching across their face or behind their head! Elaborate crowns can have more than one segment, grow big (past the cheek), have complex shapes or gemstone addons.
Fanged (Rare) Masterlist Examples
Some Beastlings grow large fangs or tusks that remain visible even when they close their mouth.
NOTE: sharp teeth that are not visible through a closed mouth or tiny vampire fangs that slightly peek out from the top lip do not need this trait!
