Orb of the dryad

This wooden orb glowing with golden light speaks of pleasantry to be had.
Natures Light: When attuned this orb shall float in any place in a 5ft radius around you. On command, it sheds bright golden light for a 20ft radius and dim light for an additional 20.
Healing Flight: As an action, you can make the orb float in a straight line towards a creature withing 100ft. The orb becomes ethereal and heals every single creature it passes through for 1d4+1. When it arrives at your chosen target it hovers next to it and heals the creature for 1d4+1 for the following 3 rounds. Afterwards, it returns to you if you are still within 100ft or fall onto the floor.
The ethereal orb can penetrate most barriers, but it is blocked by 1 foot of stone, i inch of common metal and a thin sheet of lead, or 3 feet of wood or dirt.
Requires Attunement.
