Duality of Life and Death

Based on Janus, Roman god of Transitions and Duality, Beginnings and Endings. Would fit a split personality with one for Life, other Death, with some grave to be the balance in between. 

Bonus Proficiency

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

Circle of Mortality

At 1st level, you gain the ability to manipulate the line between life and death. When you would normally roll one or more dice to restore hit points with a spell to a creature at 0 hit points, you instead use the highest number possible for each die.

In addition, you learn the Spare the Dying cantrip, which doesn't count against the number of cleric cantrips you know. For you, it has a range of 30 feet, and you can cast it as a bonus action.

Channel Divinity: Touch of Death

Starting at 2nd level, you can use Channel Divinity to destroy another creature's life force by touch. When you hit a creature with a melee attack, you can use Channel Divinity to deal extra necrotic damage to the target. The damage equals 5 + twice your cleric level.

 

Sentinel at Death's Door

At 6th level, you gain the ability to impede death’s progress. As a reaction when you or an ally that you can see within 30 feet of you suffers a critical hit, you can turn that attack into a normal hit. Any effects triggered by a critical hit are canceled.

You can use this feature a number of times equal to your Wisdom modifier (minimum of once). You regain all expended uses when you finish a long rest.

Divine Strike

At 8th level, you gain the ability to infuse your weapon strikes with divine energy. Once on each of your turns when you hit a creature with a weapon attack, you can cause the attack to deal an extra 1d8 necrotic damage to the target. When you reach 14th level, the extra damage increases to 2d8.
