Styx Domain

He or she controls the lives of those on the battlefield, whether saving those in need or guiding them across the river of Styx. No one is your equal, with one foot in the grave and the other in the light. You have become intimate with death on the city streets and on the front lines of the battlefield, while not thriving for it you have instead embraced it. With your thirst for knowledge of Pelor and Kelemvor through practical experiences, you now watch over life and death.

Bonus Proficiency

When the cleric chooses this domain at 1st level, he or she gains proficiency with martial weapons.

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: Path to the Grave

Starting at 2nd level, you can use your Channel Divinity to mark another creature’s life force for termination.

As an action, you choose one creature you can see within 30 feet of you, cursing it until the end of your next turn. The next time you or an ally of yours hits the cursed creature with an attack, the creature has vulnerability to all of that attack’s damage, and then the curse ends.

Sentinel at Death’s Door

At 6th level, you gain the ability to impede death’s progress. As a reaction when you or a creature you can see within 30 feet of you suffers a critical hit, you can turn that hit 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.

Potent Spellcasting

Starting at 8th level, you add your Wisdom modifier to the damage you deal with any cleric cantrip.

Keeper of Souls

Starting at 17th level, you can seize a trace of vitality from a parting soul and use it to heal the living. When an enemy you can see dies within 60 feet of you, you or one creature of your choice that is within 60 feet of you regains hit points equal to the enemy’s number of Hit Dice. You can use this feature only if you aren’t incapacitated. Once you use it, you can’t do so again until the start of your next turn.
