One of the most common traditions of corceïs is stinger carving/molding!

Many yearlings get the chance to start already shaping their stingers via gradual carving as they grow (some will even carve their horns!) Or, using molds that are changed every month as the stinger develops! Always leave at least one sharp end for the stinger to develop fully.

There are also many ways to contribute to their stinger gaining a particular shape, since as special vitamins that help it grow more prominent, stingers only stop growing once they reach adulthood (you can read more on Life Cycle about their life stages!).

Cors can have those traits for free! You can read more about it on Traits.

Their stingers can be naturally curved, have spikes, extra ends, sharp turns, etc.

However, their stingers do not naturally have slits or openings; they also do not resemble shapes like hearts and stars! So, any stinger with an unnatural shape or even carvings on it will need this trait!

On the right side, you can view an example of a stinger with the Modified Stinger trait and a natural one!

A reminder that both still require to have at least one sharp end! As for horns/stingers with carvings (letters, symbols, etc), you may use the Carved Horn/Stinger trait! Though it does not change the shape of the horn.
