The Red Moon Wyrm
Festival colossus · Blood Moon Festival
When the moon turns red it comes down out of it: a long, thin dragon the color of a wound, coiling over the Market rooftops by night and climbing out of reach by day.
Its mechanic: On the wing
By day on the valley clock it circles high out of reach: only vampires with an avian companion can chase it then. At night it comes low enough for anyone. Under a full moon everyone hits half again as hard.
Rare looks it drops
Everyone who strikes it has a chance at one piece whose look they haven't collected yet. Soulbound, and kept in the Wardrobe for good.
