The Lore Podcast (https://www.lorepodcast.com/ ) just did an episode about healing with corpses. Let’s do that for clerics!
Corpse Healer Domain
The dead hold gateways for the living. Hangmen long ago learned that corpses still held life and they could wield that life to heal the sick. Your god guides you to use the dead to save the living. Some see your rites and religion as profane casting you out to the outskirts of society, but when your detractors become ill, they all come to see you no matter how much they detest you.
|1st||inflict Wounds, cure wounds|

|5th||remove curse, revivify|
|7th||death ward, raise dead|
|9th||mass cure wounds, raise dead|
Disciple of Life
Starting at 1st level, you learn to channel the powers of life to heal your friends through use of blood. If you use blood as a material component of a creature that died in the last hour as you cast a healing spell, you heal the target a number of extra hit points equal to the challenge rating the creature had. A creature has a number of doses of blood equal to its size category with tiny having 1 and gargantuan having six doses.
Starting at 2nd level, you can use your Channel Divinity to enhance your allies.
As an action, you present a severed hand of a hanged craftsman or warrior who fell in battle. Any allies within 30 feet of you, gains a 1d4 to their next skill checks or attacks chosen by you, for the next minute.
Beginning at 6th level, the dead begin to take the injuries of the living. As an action, you can use body of a recently living creature, no undead or fiends, to cast remover curse or lesser restoration. At level 12, you can use a body to cast dispel evil and good or greater restoration. Each corpse may be used once in such a way.
At 8th level, you learn from your headsman forebears and gain the sneak attack ability of a rogue half your level if you wield an ax of any kind.
Starting at 17th level, you can use the body of any creature that died in the last minute as a material to cast true resurrection on any creature that also died in the last minute. If you do so, you do not need to have prepared the spell, the spell does not cost any additional material components, and the casting time drops to one minute. Killing a creature solely to fuel this ability may be seen as an evil act and may cause your god to reject the spell.
