Oath of Purification

In a world teeming with evil and darkness, some crusaders find that revealing the evil to the light of day is not enough - evil must be purged to ashes itself. A growing respect for the cleansing power of divine fire leads these warriors to the Oath of Purification. Known for leading torch-wielding mobs, organizing ruthless inquisitions, and putting evil to the pyre, these paladins are devoted to purity by the flames.
With their rigid adherence to the concept of purity, those who follow the Oath of Purification rarely deviate from swearing to the purest conceptions of the oath's tenets. The oath emphasizes purity, but its followers run the gamut of alignments based on what they personally believe to be pure and what they see as corruption. The tenets of purification are:

Tenets of Purification:

Banish the Darkness: With Darkness comes terror, and with the light of fire comes courage. The purity of my purpose must drive out the uncertainty, fear, and doubt I encounter.
Cleanse All, Even Oneself: Evil and corruption must be cleansed at every turn, no matter the cost. If evil is given time to fester, it will spread like a cancer. If corruption takes hold within my heart, it too must be cleansed before anything else.
Leave No Trace of the Evil: If those who come after can glean the truth of my enemies' evil from the ashes I leave, it means the ashes were not burned enough. Justice, sagacity, honesty, and all other such concerns are second to cleansing evil so thoroughly that it is completely forgotten.
Purity Only Through Pain: There is no painless method for cleansing corruption, even within myself. Those who seek to purify without causing pain will fail to purify anything.
Share the Flame: As one torch can light another, my righteous flame of purity can inspire others who are not yet corrupted to take up my cause, and I will lead those with smaller flames until they grow like a blazing beacon against the night.

Channel Divinity When you take this oath at third level, you gain the following two Channel Divinity options.
Cloaked in Fire: You can use your Channel Divinity to wreath yourself in magical golden flames. As an action, you become surrounded with fire that scorches your foes without harming you or your equipment. Each enemy creature within 10 ft of you must make a Dexterity saving throw. A Target takes fire damage equal to 2d6+half of your paladin level on a failed save, or half as much on a success.
Until the start of your next turnb, the flames continue to burn, shedding bright light in a 20 ft radius and dim light for an additional 20 feet and each enemy creature that ends its turn within 10 ft of you takes fire damage equal to 2d6+half your paladin level.
Purifying Flames: You can use your Channel Divinity to imbue a target with purifying flame that does not burn them. As an action, you fill one creature that you can see within 60 ft of you with divine fire, and any creature inside the creature the target's body or possessing the target take fire damage equal to twice your paladin level. Additionally, you can either cure the target of one nonmagical disease inflicting it, or end one of the following effect inflicting it; blinded, charmed, deafened, paralyzed, or poisoned.
Aura of Warmth: At 7th level, you gain an aura of warmth that tempers flames. While you are conscioud, you and any friendly creatures within 10 ft of you have resistance to fire damage and advantage on saving throws against spells or abilities that deal fire damage.
At 18th level, the range of this aura increases to 30 ft
Purge by Fire Starting at 15th level, when you deal fire damage with a spell or paladin class feature to a creature you can see within 120 ft of you, you can choose to instantly cast dispel magic on that creature without expending an action and without requiring components. You can do this even if you do not have dispel magic prepared.
Once you have used this ability, you cannot do so again until you finish a short or long rest.
Eradicating Flame When you reach 20th level, you can use your action to ignite one weapon you are holding with divine flame. The weapon is engulfed in roaring golden flame that doesn't harm the weapon or you. The fire sheds bright light for 20 ft and dim light for an additional 20 ft, and lasts for 1 minute or until you stop holding the weapon. The fire cannot be estinguished by normal means.
Melee attacks you make with the flaming weapon have advantage. When you hit with such an attack, the weapon deals an additional 1d10 radiant damage and 1d10 fire damage, and if the target is flammable or is a creature, it is lit ablaze. Until someone takes an action to douse the fire, it takes 1d10 fire damage at the start of its turns. If damage from the attack or the fire kills a target, the target is turned to ash.
Once you have used this ability, you cannot use it again until you finish a long rest.
