Lifesong Planedancer

You were once a normal cleric, until one day you had a run in with something that pulled you in the "In-Between", which caused every part of you to be fractured across time, space, and the planes of reality. Luckily for you, you were brought back by the melody of the earth, and managed to collect part of yourself on the earth.

Utilizing parts of you from across the "In-Between", you can summon duplicates that can support your allies with your "Channel Divinity: Duplicity of the Savior", heal with melee damage, give temporary hit points, gain damage benefits upon damaging others, and save your allies from certain death.

Heavy Armor Proficiency

When you choose this domain at 1st level, you gain proficiency with heavy armor.

Overhealing Soundtrack

Also starting at 1st level, your healing spells give temporary hit points. Whenever you use a spell of 1st level or higher to restore hit points to a creature, the creature gains temporary hit points equal to the spells level plus your proficiency modifier.

Channel Divinity: Duplicity of the Savior

Starting at 2nd level, you can use your Channel Divinity to summon a duplicate of yourself.

As an action, you call upon a duplicate of yourself and they appear in a space within 5 feet of you. This creature has all of your attributes, except their HP, which is always left at 1 HP.
They can use actions depending on your level. They use your bonus action.

Passive: Any individual within 5 feet of your duplicate are healed for 1d4+your proficiency modifier on the start of your turn. This healing cannot heal a creature on death saving throws.
2nd Level: Your clone gains the ability to cast cure wounds. The level is level - (proficiency modifier * 2). The lowest this can be is 1st level.
6th Level: Your clone gains the ability to cast spare the dying and save any individual on death saving throws.
11th Level: The cure wounds level is now calculated as level - proficiency modifier.
16th Level: Your clone gains the ability to cast revivify equal time to your proficiency modifier.

Beats of the Earth

Beginning at 6th level, your melee attacks heal allies. Once per turn, hitting an enemy heals your ally for your weapons damage modifier + your spell caster modifier.

Give-Back Melody

At 8th level, when you heal another individual with a level 1 spell or higher, you gain advantage and additional 1d8 (at level 8) or 2d8 (at level 14) of radiant damage on your next attack. This lasts until the end of your next turn.

Last Dance

Starting at 17th level, when an ally takes fatal damage, you can use your reaction to heal them for your level + your spell casting modifier. You can do this as many times as your proficiency modifier.
