Amplifying Bond

This spell energizes a willing creature you touch and creates a mystic connection between you and the target until the spell ends. While the target is within 60 feet of you, it gains a +1 bonus to attack and damage rolls, and it's attacks ignore damage resistances and immunities. Each time it deals damage, you take damage equal to a quarter of the damage dealt rounded down.

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.
