You touch and enhance a pool of water so that it heals all who enter it. You do so by sprinkling crushed bits of the material components into fairy dust, then sprinkling this dust through the pool. The pool of water cannot be more than 200 feet across at widest point and can be no more than 5 feet deep. For the duration, any living creature that begins its turn in the pool recovers heart points equal to your casting ability modifier (minimum 1). If a creature spends the entire duration in the pool, it ultimately recovers heart points equal to 100 x your casting ability modifier.
     Any creature that starts its turn in the pool or enters it on its turn is absolved of all the following conditions: blinded, deafened, ignited, frozen, paralyzed, petrified, and poisoned.
     Undead and constructs are unaffected by this spell.
