Protection Domain

As a Cleric of protection Domain you've dedicated yourself to protecting those around you. Gods of this domain are those of Life, Light, and War.

Guardian of Life

 you gain the ability to keep those around you from crossing 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 reaction.

Channel Divinity: Rebuke the Violent

You can use your Channel Divinity to rebuke those who use violence. Immediately after an attacker within 30 feet of you deals damage with an attack against a creature other than you, you can use your reaction to force the attacker to make a Wisdom saving throw. On a failed save, the attacker takes radiant damage equal to the damage it just dealt. On a successful save, it takes half as much damage.

Sentinel of Life

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

Potent Spellcasting

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

Immotable Defense

At 17th level, you gain resistance to two damage types of your choice, choosing from bludgeoning, necrotic, piercing, radiant, and slashing. Whenever you finish a short or long rest, you can change the damage types you chose.

As an action, you can temporarily give up this resistance and transfer it to one creature you touch. The creature keeps the resistance until the end of your next short or long rest or until you transfer it back to yourself as a bonus action

Bonus Proficiency

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

Disciple of Health

Also starting at 1st level, your healing spells are more effective. Whenever you use a spell to a creature, the creature regains additional hit points equal to your proficiency bonus + the spell’s level.

Channel Divinity: Preserve Life

Starting at 2nd level, you can use your Channel Divinity to heal the badly injured.

As an action, you present your holy symbol and evoke healing energy that can restore a number of hit points equal to five times your cleric level. Choose any creatures within 30 feet of you, and divide those hit points among them. This feature can restore a creature to no more than half of its hit point maximum. You can’t use this feature on an undead or a construct.

Blessed Healer

Beginning at 6th level, the healing spells you cast on others heal you as well. When you cast a spell of 1st level or higher that restores hit points to a creature other than you, you regain hit points equal to 2 + the spell’s level.

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 radiant damage to the target. When you reach 14th level, the extra damage increases to 2d8.

Supreme Healing

Starting at 15th level, when you would normally roll one or more dice to restore hit points with a spell, you instead use the highest number possible for each die. For example, instead of restoring 2d6 hit points to a creature, you restore 12.
