Deacon's Chain Heal

A creature you can see within range regains hit points equal to 1d6 + your spellcasting ability modifier. In addition, whenever you heal a creature with this spell you may target one additional creature within the remaining distance of the original target. That second creature regains hit points equal to half (rounded down) the amount healed on the first target. This ability has no effect on undead or constructs.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the healing increases by 1d6 for each slot level above 2nd.
