At 1st level, you become proficient in the Survival skill. Your proficiency bonus is doubled for Survival checks when tracking evil alignment creatures, or tracking Monstrosity type creatures.

(See end of this domain for the spell sheet)

When you choose this domain at 1st level, you gain the Marked for Healing cantrip if you don't already know it.

A void domain cleric may follow gods such as; Tempus, Savras, Shar, and Kelemvor. Void domain clerics see life as a pain filled existence until they and others are freed from it to live amongst the gods. However they also believe living beings shouldn't be killed or die before their time, and therefore attempt to preserve life and fight the monsters who should take the lives from others, and hopefully don't become a monster themself...

A high elf stands above her injured and dying friends. Several Orcs stand mighty and proud of their acheivement. The high elf looks to her holy symbol and brandishes it like a knife, her appearance taking a dark turn, as she embraces the power of the void.

Channel Divinity: Voidform

Starting at 2nd level, you can use your Channel Divinity to draw life from your enemies and to heal yourself.

For the next minute any spells or cantrips you cast (of 5th level or lower) that heal can instead deal damage. (the damage type is necrotic) Additionally, you heal for half of the damage die you deal with healing spells/cantrips.

Healing spells/cantrips can target enemies whilst in this form, but still follow all other rulings (i.e. has no effect on undead/constructs).

Healing spells that target multiple creatures can either be used to heal, or deal necrotic damage. (i.e. you cannot have some creatures targetted by Mass Cure Wounds be healed and some be damaged)

Save the Bloodied

At 6th level, you may use your reaction to prevent an injured ally (that is within 30ft) from dropping to 0 hit points. They instead drop to 1 hit point. After you use Save the Bloodied, you cannot use it again until you finish a long rest.

Potent Spellcasting

Starting at 8th level, you add your Wisdom modifier to the damage you deal with any cleric cantrip. (This includes Marked for Healing whilst in Voidform)

Monster of the Void

At 17th level, you have gazed into the Void for far too long and as it gazed back, you became the monsters you once feared and detested.

You are no longer humanoid, and are instead the monstrosity type. You have disadvantage to Persuasion (Charisma) checks against humanoids, however you gain a +4 bonus to damage rolls (including damage from healing spells whilst in Voidform) against monstrosities.
