Wondrous Item, artifact (requires attunement by a by a Druid, Artificer, Ranger)
A small acorn encased in amber, fixed on a light silver-ish chain. The amber has an oak tree engraved on its surface.
Once per day, you may activate this amulet to cast a healing spell that gives 3d6+2 HP up to six animals and non-humanoid creatures (animals, creatures, familiars, and any other crafted or otherwise non-humanoid) in a 30-foot-radius sphere centered on that point.
Each target regains hit points equal to [roll]3d6+2[/roll] . Once you use the acorn, it can't be used again until the next dawn.
