Circle of Healing

You create a 10 foot circle of green light with glyphs floating around it (also green). Roll N d6's where N=1 + your spell casting ability modifier (minimum 2). This is the maximum number of points in your circle's pool. 

Until the spell ends, whenever you or a creature you can see moves into the circle for the first time, or starts its turn there, you can choose to act on that creature. 

If the creature is undead, fiend or construct:

• use points from the pool to directly damage (no save, no attack) that creature.
• the damage counts as radiant damage

Else:

• use points from the pool to restore hit-points to the target creature

Deduct the points from the pool after each action (healed or damaged). If there are no points left, the spell ends.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the circle's pool increases by 1d6 for each slot level above 2nd.
