The Headless Rider

Level 64 · Boss · attacks on sight.

“He lost his head a long time ago and he is still looking for it, at a gallop. Nothing touches him in the saddle. A pumpkin in his road does.”

An open boss: it belongs to nobody. Everyone who does their share of the damage (5% of its health) gets their own kill and their own drops, and a report when it falls.
