Bracelet of Twined Favor (5e Equipment)

Wondrous item, very rare (major) (requires attunement by a spellcaster)

While you wear this bracelet, when you cast a spell that restores hit points to a creature other than you, you may regain a number of hit points equal to the number the spell restored. Once you use this property of the bracelet, you can't use it again until the next dawn.
