Let’s add one more part to the Monk of the Healing way…

The Price of Healing, Greater-When you use your channel divinity class feature, if you heal an enemy, roll the dice as normal.  For each enemy healed in this way, you may heal an ally the same number of hit points is maximized and multiplied by 1.5.  The healed enemy must have been damaged during the battle, you may not benefit from this ability by healing an enemy who is at full hit points.  If no legal targets exist for this ability, it has no effect.
