D&D 5e

60. Healer's Sash
Wondrous item, uncommon
This magic sash resists staining by blood or gore - a testament to its latent restorative power.
As a bonus action, you can choose two willing creatures within 30 feet of you that you can see. One of the creatures loses 1 Hit Die, and then the other creature regains hit points as if it had spent a Hit Die of its own. You must then finish a long rest before you can use the sash again.
