Skeleton curse cosmetic!

This could be a microtransaction but I think it would be a lot cooler as a reward from a really hard voyage or event. The actual cosmetic would be a curse that turns your character into a skeleton at midnight and until the sun rises. Basically just a fun cosmetic that makes your character a bit more dynamic and perhaps it can change the emotes or something. Basically the curse from pirates of the caribbean. As I said this could be a microtransaction and I think it would do quite well but it could also be a really cool event or voyage. Obviously it would come from the hoarder of souls sending you on a mystical quest. You fight your way through pirates into a deep cave and as you kill a boss you are cursed and given a necklace or something which is the physical representation which you can take off if you don't want the effect. Would love some better ideas on what the voyage/event could be. And if this is even something people want.
