Tasha’s Cauldron of Everything introduces the Peace Domain for the Cleric; which at level 2 gains the Balm of Peace Channel Divinity option
You can use your Channel Divinity to make your very presence a soothing balm. As an action, you can move up to your speed, without provoking opportunity attacks, and when you move within 5 feet of any other creature during this action, you can restore a number of hit points to that creature equal to 2d6 + your Wisdom modifier (minimum of 1 hit point). A creature can receive this healing only once whenever you take this action.
How many creatures can this target within the movement? If I move through the entire party can I heal them all? Or does this only refer to a single creature?
It reads to me that I can target as many as I can reach with my movement, especially given the last line, but the any other creature, and that creature lines give me pause for thought.
