There's a Christmas event going on right now! (don't mind the translation it's a little wonky right now lol)
All dragons are able to breed with each other and don't have any restrictions (example: Lunera and Artemis normally can't breed together because they're natural enemies). Hell Dragon in particular could not breed with itself before, but during this time of festive unity, they can! This opens the door to special pure-lineage only personalities like pure/classy that it couldn't get before!
You can also send dragons to help Santa (they'll come back to you btw) and, when enough time has passed, you can get a special egg! This egg has a chance to be the species* that helped Santa, a random egg from a select list, or a special xmas dragon! Any dragons obtained from this will also have a chance to have either the Christmas personality or the Affable personality. You can also receive an item to apply these two personalities to your own dragons once you've helped Santa enough!
*there are some restrictions to what dragon you can get, mainly anything that costs diamonds to obtain or through special action or an achievement/reward from a mechanic
You can get G1 hybrids from sending dragons to Santa, meaning that for the first time ever, hybrids can get pure or classy personality! I so desperately want that classy aura on a Dream Water dragon, I think the bubbles would go so well with it!
Hope you all enjoy this special event! \o/
