Aresta's Magical Mist

A thin light-green mist slowly appears in a 60-foot-radius sphere from a point you choose within range. Choose up to ten creatures within the radius of this spell each turn. Each target regains hit points equal to 5d6 + your spellcasting ability modifier. This spell has no effect on undead or constructs. While concentrating on this spell you can't use your action or reaction and your speed is half. If you are forcibly moved in any way you must roll with disadvantage to maintain concentration. If you cast this spell for the full duration in the same outdoor place every day for a year, a weaker version of the spell remains permanently there, healing all creatures in its area for 1d8 per round (10d8 per minute).
