Tranquility

You spread a handful of Moonberry Seeds around you in a circle that will expand until a beautiful garden with a silver glow that will spread rapidly in a 30 foot radius.  All allies in the 30-foot-radiuscentered on the area you first casted the spell will regain hit points equal to 4d10 + your spellcasting ability modifier. 

Allies will keep being healed in this manner at the start of the casters turn until the spell is ended by losing concentration or the duration ends.
