Mastery of Life

Reaper of Life:

You have devoted your life to protecting others, going so far as to delving deep into the secrets of harnessing even the most devastating powers to restore life instead.

As an action, you may sacrifice your own life-force, reducing your current hit points by any amount of your choice (this can not be reduced in any way). This is then temporarily stored into a pool of hit points equal to 6 times the value sacrificed. This pool may then be distributed between any amount of allies within your line of sight, healing them for an amount of Hit Points equal to that expended from the pool.

Alternatively, you may choose to forgo expending hit points, to instead immediately die, filling your allies with the full extent of your life force. Choosing to willingly perish in this way bypasses Death Ward, and any similar items, spells or abilities that may prevent your death. You cannot be revived by any spell less than Raise Dead, healing an amount of allies up to your Proficiency Bonus to maximum Hit Points, and purging all condition effects in the process.

You may use this ability once per long rest, unless you expend a usage of your Channel Divinity to do it again.
