Blood Tether

You create a mystical bond between yourself and an ally within range, linking your life forces. When an ally linked by the Blood Tether is in danger, you can use your reaction to pull them to safety, swapping places with them instantly. Alternatively, you can grant your ally advantage on their next attack roll or saving throw. While the spell is active, both you and your ally gain temporary hit points equal to your spellcasting ability modifier at the start of each of your turns.
