Chain of Vitality

You invoke a mystical chain of healing energy connecting you and an ally within 30ft of you. For the duration, as a bonus action on your turn you may heal your ally for 1d6 plus your spellcasting modifier and/or transfer the chain to another ally. If you and the connected ally become more than 30ft apart the chain breaks and the spell ends. This spell has no effect on undead or constructs.

At Higher Levels: for every level above 3rd you cast this spell you may effect one more ally.
