Bond of Protection

This spell wards a willing companion you touch and fully opens the mystic connection between you and the target until the spell ends. While the target is within 60 feet of you, you both gains a +1 bonus to AC and saving throws, and have resistance to all damage. Also, if one bonded companion is reduced to 0 hit points, the other becomes unconscious.

The spell ends if you drop to 0 hit points or if you and the target become separated by more than 60 feet. It also ends if the spell is cast again on either of the connected creatures. You can also dismiss the spell as an action.
