2nd-level conjuration

Casting Time: 1 bonus action
Range: 60 feet
Components: V, S
Duration: Concentration, up to 1 minute

You call forth a nature spirit to soothe the wounded. The intangible spirit appears in a space that is a 5-foot cube you can see within range. The spirit looks like a transparent beast or fey (your choice). Until the spell ends, whenever you or a creature you can see moves into the spirits space for the first time on a turn or starts its turn there, you can cause the spirit to restore 1d6 hit points to that creature (no action required). The spirit can’t heal constructs or undead. As a bonus action on your turn, you can move the Spirit up to 30 feet to a space you can see. The spirit can heal a number of times equal to 1 + your spellcasting ability modifier (minimum of twice). After healing that number of times, the spirit disappears.

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