Arcane Aid

As an action, you point to a parcel of ground within range and summon a 5 ft cube on top of it. A creature of your choice that you can see within the cube regains hit points equal to 1d4 + your spellcasting ability modifier. As a bonus action while maintaining concentration, the caster may move the cube up to 30 feet and bestow healing on the same or a different target.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the healing increases by 1d4 for each slot level above 1st.
