1/day- When character wearing the Charm falls under 0 HP the Ivory Rhapsody Charm uses their life force to cast Animate Dead and turns the wearer into the appropriate Skeleton up to Large Size (5HD). In doing so, the remaining muscle and skin erupt in disgusting green flame, all those within 10ft are sickened(fort save DC 13) for 1d4+1 rounds. (remove disease cancels the sickening on one character)

The new creature is an uncontrolled undead with no memories of life.

Craft Wonderous Item- Caster level 10, Animate Dead, Ghoul Touch, 10,000Gp

Often a lord will give it to a expendable servant as a lucky charm and the faithful minion will be duped into undead servitude.
