Tremendous Teamwork

This spell wards a willing creature you touch and creates a mystic connection between you and the target until the spell ends. While the target is within 30 feet of you, it has resistance to all damage. Also, each time it takes damage, you take the same amount of damage.

The spell ends if you drop to 0 hit points or if you and the target become separated by more than 30 feet. It also ends if the spell is cast again on either of the connected creatures. You can also dismiss the spell as a bonus action. If you choose to dismiss the spell, you and the target each regain hit points equal to your proficiency bonus plus the level of spell slot that you used to cast the spell.
