Binding Vitality

In this cruel world its good to have help bearing my burdens.

You reach out and touch a creature binding the vitality of both your bodies. If the creature is unwilling said creature must make a constitution saving throw. If failed the caster and the target share both damage and healing received. Should the caster or target receive damage or healing the value is split evenly to the effected bodies (rounded down if it splits into a decimal). If any of the effected bodies has resistance to the given damage type that resistance is not shared between the effected bodies.
