Channel Divinity

When you take this oath at 3rd level, you gain the following two Channel Divinity options.

• invoke pestilence. you target a creature and they are plagued with pestilence each time they take a long rest they gain one level of exhaustion and gain additional effects 

1st level of exhaustion. Bleeding under the skin or from the mouth, nose, or botto

2nd level of exhaustion. Blackened skin, especially on the nose, fingers, and toes

3rd level of exhaustion. Belly pain, diarrhea, vomiting, and shock

4th level of exhaustion. cough sometimes with blood

5th level of exhaustion. Trouble breathing, Nausea and vomiting

6th level of exhaustion. DEATH

• Turn the Faithless. You can use your Channel Divinity to utter ancient words that are painful for fey and fiends to hear. As an action, you present your holy symbol, and each fey or fiend within 30 feet of you that can hear you must make a Wisdom saving throw. On a failed save, the creature is turned for 1 minute or until it takes damage.

A turned creature must spend its turns trying to move as far away from you as it can, and it can't willingly move to a space within 30 feet of you. It also can't take reactions. For its action, it can use only the Dash action or try to escape from an effect that prevents it from moving. If there's nowhere to move, the creature can use the Dodge action.

If the creature's true form is concealed by an illusion, shapeshifting, or other effect, that form is revealed while it is turned.

Aura of Sickly Protection

Beginning at 7th level, ancient sickness lies so heavily upon you that it forms an eldritch ward. You and friendly creatures within 10 feet of you have resistance to damage from spells.

At 18th level, the range of this aura increases to 30 feet.

Undying Sentinel

Starting at 15th level, when you are reduced to 0 hit points and are not killed outright, you can choose to drop to 1 hit point instead. Once you use this ability, you can't use it again until you finish a long rest.

Additionally, you suffer none of the drawbacks of old age, and you can't be aged magically.

this is due to the sickness being in your lifeblood

Elder Pestilence

At 20th level, you can assume the form of an ancient force of Death, taking on an appearance you choose. For example, your skin might turn green or take on a black-like(sickly) texture, your hair might become moss-like.

Using your action, you undergo a transformation. For 1 minute, you gain the following benefits:

• At the start of each of your turns, you lose 10 hit points.

• Whenever you cast a paladin spell that has a casting time of 1 action, you can cast it using a bonus action instead.

• Enemy creatures within 10 feet of you have disadvantage on saving throws against your paladin spells and Channel Divinity options.
• everyone within 30 feet of you gains the plague

Once you use this feature, you can't use it again until you finish a long rest.
