Anodyne

A fine glowing mist materializes in the air, particles of divine magic bestowing blessed healing upon the living, as well as blistering destruction upon the undead.

A 20-foot radius sphere of dim light appears at a point you can see within range. For every 5 feet a living creature moves through this space, it is healed for 1d4 hit points. Additionally, an undead creature that moves through the space suffers 1d4 points of radiant damage for every 5 feet it moves through the same space. This mist can be dispersed for 1 round by a strong wind, such as from the gust of wind, but it returns at the end of your next turn.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the healing (and damage) increases by 1d4 for every two slot levels above 5th.
