Healing Spirit

You call forth an intangible beast or fey in a 5ft
cube within 60 ft of you that heals the wounded.
For one minute, any creature that starts its turn
within 5ft of it or moves through it for the first
time heals 1d6 hit points with your discretion.
This can only happen (1+ your wisdom modifier)
times before the spirit disappears. You may move
the spirit up to 30 ft as a bonus action.
The healing increases by 1d6 for each spell slot
you use above 2nd.
