Cleric Domain: Immortaility

The Immortality domain teaches one that teaches that your body is a temple, and that you only need it and the divine power given by your god to serve them. Most Immortality priests on Malyk worship the goddess of innovation: Ultima.

Unbound

At 1st level, you relinquish the need for weapons and armor. While unarmored, and not wearing a shield, you have an Armor Class of 13 + your Wisdom modifier. Additionally, while not wielding any weapons, you are proficient in unarmed attacks, which deal 1d8 + your Strength modifier, instead of the normal damage for an unarmed strike.

Divine Body

Also at 1st level, you gain proficiency in the Acrobatics and Athletics skills, and your proficiency bonus is doubled for any ability check you make that uses either of those skills.

Channel Divinity: Perfect Soul

Starting at 2nd level, you can use your Channel Divinity to sustain yourself. As a bonus action, you gain temporary hit points equal to twice your cleric level and resistance to bludgeoning, piercing, and slashing damage for one minute.

Body and Steel

At 6th level, you have learned how to harness and copy the magical essence of weapons and armor.
You may spend an hour with a magical weapon. When you do, your unarmed strikes gain the benefits of that weapon, and counts as magical for overcoming damage resistance. This does not change the base damage or type of your unarmed strikes, but will give any magical bonus to attack and damage rolls. While an weapon effect is copied, you can attack twice, instead of once, whenever you take the Attack action on your turn.
You may spend an hour with a magical piece of armor. When you do, you gain the benefits of that armor. This does not change your base Armor Class calculation, but will give any bonus to Armor Class. 
If either of these pieces of equipment require attunement, copying this effect is treated as an attunment. You may end the effect of any of these effects during a long rest. You must meet any racial, class, or level requirements of enchantments copied.

Unyielding Endurance

At 8th level, whenever you take damage, you may reduce that damage by an amount equal to your cleric level. You may use this ability a number of times equal to your wisdom modifier (min 1).

Beacon of Immortality

At 17th level, you overcome the limits of mortality. You cease to age. In addition, you may spend 1 minute to planeshift to the realm in which your diety resides. If you are already in such a realm, you may instead return to the material plane.
In addition, your maximum hit points increase by 50 and you gain a permanent +2 to your Armor Class.
