Neat thing about disco is that technically it counts as undead too! It has a cursed, resurgent existence, but frequently only with arcane equipment. People make the same face hearing it as they do smelling a grave. –and who can forget MJ’s Thriller? Undead DO move that way!

Btw, duplicating refractive effects is TOUGH.
