Oath of Pestilence

Clad in grime-soaked armor and wielding rusting
weapons, the Oath of Pestilence paladin spreads
corruption, disease, and filth. Bound by an oath which
infests their bodies with all manner of plagues, these
heralds of decay lumber forward with unholy toughness
and grim resolve.

Tenets of Pestilence
The tenets of the Oath of Pestilence emphasize the role of
disease as a purifying element in the cycle of life.

Strength in Resilience. Surviving hardship and
plague make you stronger. Spreading these things causes
strength to flourish.

All Things Must Pass. Death is the natural
conclusion of life. There is nothing unnatural or immoral
about the ending of life.

Might Makes Right. The laws of mortals mean
nothing to poxes and plagues, they go where they wish
and take what they want. So should you.

Channel Divinity

3rd-level Oath of Pestilence feature

You gain the following two Channel Divinity options. 

Debilitating Fever. Your touch inflicts disease. Make a melee spell attack against a creature within your reach that isn’t a construct or undead. On a hit, the creature becomes diseased and is incapacitated (incapacitated) for 1 minute. At the end of each of the diseased target’s turns, the target can make a Constitution ([saving throw]Con[/saving throw]) saving throw. On a success, the target is no longer diseased, and the effect ends. Since this ability induces a natural disease in its target, any effect that removes a disease or otherwise ameliorates a disease’s effects apply to it

Inspiring Smite. You can use your Channel Divinity to weaken a creature against entropic energies. As an action, you can force a creature of your choice that
you can see within 30 feet of you to make a Constitution saving throw. On a failed save, for the next minute the creature takes an additional 2d6 damage the first time it takes necrotic damage each turn. During this time, the creature loses resistance to necrotic damage if it has it.

Aura of Rampant Sickness

7th-  and 18th-level Oath of Pestilence feature

You emit an aura of contagion and virulence to a range of 10 feet. When a creature within your aura makes an ability check, attack roll, or saving throw you can give that roll disadvantage as a reaction.

When you reach 18th level in this class, the range of the aura increases to 30 feet.

Disgusting Resilience

15th-level Oath of Pestilence feature

When you take damage which would reduce you to 0 hit points, you can choose to expend any number of Hit Dice. Roll those dice and subtract the result from the damage taken. If this reduces the damage to 0, you don’t take any damage.

In addition, if you are killed your corpse violently explodes in a shower of pus and gore, dealing 8d6 necrotic damage to creatures within 20 feet of you that fail a Constitution saving throw.

Plaguebringer

20th-level Oath of Pestilence feature

You can empower yourself with the legends—whether true or exaggerated—of your great deeds. As a bonus action, you gain the following benefits for 1 minute:

• • You have resistance to necrotic damage and are
  immune to poison damage and the poisoned condition.
•  Your hit point maximum can’t be reduced.

Creatures of your choice who start their turn within 5 feet of you, or who move within 5 feet of you on their turn, take necrotic damage equal to your Charisma modifier. Once a creature takes damage from this ability, it can’t take damage from it again until the start of its next turn.
