Platform of Healing

This 10-foot-diameter platform, which must be affixed to the floor when created, casts heal on any living creature that steps onto it. If an undead creature steps onto the platform, treat it as if a harm spell had been cast upon it instead, removing all but 1d4 hit points from it.

Caster Level: 9th; Prerequisites: Craft Wondrous Item, heal; Market Price: 30,000 gp.
