Trait guide
Kelptomimis must have these 4 traits no matter the rarity:
Coins
Coins are very important to Kleptomimis, as they represent both their status in deity society as well as their rarity. 
Gems can also have different cuts or shapes. Combining two different shapes will be the rarity of the rarest shape, for example, a long, cut coin would be Uncommon.
Tails
Kleptomimis tails are similar to what thieves use to store their stolen goods: bags! Their tails are typically long and drag along the ground, made of of materials such as cotton, hemp, paper, or other fabrics. Each tail is connected to the tailbone of the Kleptomimi with a bow.
Talismans/charms
Kleptomimis must have a talisman either tied/hovering on their body or attached to their clothing. The talisman can be paper or metal with their sacred item written or drawn on it, or a simple charm of the item.
Ears & Spirit Flames
Kleptomimis can have any ears, as long as they're mammals. All Kleptomimis must also have floating mystical flames on the inside of their ears known as "Spirit Flames". Spirit flames can be any color, but must stay small enough to fit inside the ear. The more vibrant and fluttery the flame, the more energy they have. 
Extras
Kleptomimis can also have some extra traits (depending on rarity) such as wings, extra limbs, horns, plush parts, and more!
