Dungeons & Dragons 2024 (D&D) Subclass: Oath of Pestilence

Level 3: Debilitating Fever

You can inflict disease upon a creature. When you hit a creature with an attack roll using a weapon or Unarmed Strike, you can expend one use of your Channel Divinity to give that creature the Poisoned condition for 1 minute. While Poisoned in this way, the target also has the Incapacitated condition. At the end of each of its turns, the Poisoned target makes a Constitution save, ending the effect on itself on a success.

Level 3: Entropic Infection

As a Magic action, you can expend one use of your Channel Divinity and select a creature you can see within 30 feet of yourself. For 1 minute, if you deal damage to the target, the target takes an extra 2d6 Necrotic damage. In addition, the target loses Resistance and Immunity to Necrotic damage. The target can make a Constitution save against the Paladin's spell save DC at the end of each of its turns, ending the effect on itself on a success.

Level 3: Oath of Pestilence Spells

The magic of your oath ensures you always have certain spells ready; when you reach a Paladin level specified in the Oath of Pestilence Spells table, you thereafter always have the listed spells prepared.

Level 7: Aura of Rampant Sickness

You emit an aura of contagion and virulence. When a creature within your Aura of Protection is about to make a D20 Test, you can take a Reaction to impose Disadvantage on that D20 Test.

Level 15: Disgusting Resilience

When you are reduced to 0 Hit Points and not killed outright, you can spend any number of Hit Dice, roll them, and reduce the damage taken by the total rolled on those dice.

In addition, if you are killed, your corpse explodes in a shower of pus and gore. Each creature in a 20-foot Emanation originating from you makes Constitution saving throw against the Paladin's spell save DC, taking 8d6 Necrotic damage on a failed save or half as much damage on a successful one.

Level 20: Plaguebringer

As a Bonus Action, you gain the benefits below for 10 minutes, or until you end them (no action required). Once you use this feature, you can’t use it again until you finish a Long Rest. You can also restore your use of it by expending a level 5 spell slot (no action required).

One with Plague. You are immune to Poison damage and the Poisoned condition, and you have Resistance to Necrotic damage.

Bolstered by Rot. Your Hit Point maximum can’t be reduced.

Entropic Radiance. Whenever an enemy starts its turn within your Aura of Protection, it takes Necrotic damage equal to your Charisma modifier plus your Proficiency Bonus.
