Produced by a special needle, this magic tattoo depicts thin chain with metal barbs and uses ink that resembles liquid metal. After 24 hours your attunement to the tattoo ends, the tattoo vanishes. A creature cannot be attuned with more than one temporary tattoo of shared suffering.
Tattoo Attunement.
To attune to this item, hold the needle to a creature's skin where you want the tattoo to appear, pressing the needle there throughout the attunement process. When the attunement is complete, the needle turns into the ink that becomes the tattoo, which appears on the skin. A second matching tattoo appears on your skin in the same location.
Shared Suffering.
Whenever you suffer damage, you only suffer half of that damage and the creature with which you share the matching tattoo take the rest. This effect isn’t limited by range.
(Based on the barrier tattoo and ring of shared suffering.)
