Binding Tether

Binding Tether 3rd level Tethergy spell
Casting Time: 1 action Range: 30 feet Components: V.S.M Duration: 1 minute (Concentration)
Description
You create an ethereal chain between two creatures of your choice linking their Pneumatic Energy together. Both creatures must succeed on a Wisdom saving throw or be linked to the other creature, if one creature fails the spell fades even though one creature succeeded. A creature can choose to fail this save. Creatures linked by this spell share all damage and healing over the course of its duration, so if one creature would receive 10 cold damage, the creature linked to it would receive the same amount of cold damage. If a linked creature receives 10 points of healing so does the linked creature.
A tether is broken if the two individuals move more than 60 feet away from each other, if you lose concentration or if the tether is attacked in the ethereal plane. It is also affected by Dispel magic and similar abilities.
