Chain Heal

You create a bolt of radiant energy  that arcs toward a target of your choice that you can see within range. Three bolts then leap from that target to as many as three other targets, each of which must be within 30 feet of the first target. A target can only be a creature.

The main target heals 10d8. The 2nd  target will heal for half of what the main target healed. The 3rd will heal for half of what the 2nd target healed. The 4th target will heal for half of what the 3rd target healed for.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, you may add 2d8 for each higher level
