Oath of Swailing

The who take this oath realize the only way to purge evil from their word is with fire-- so they arm themselves with the fire in their soul and the pure golden flame of radiance.
So-called Swailers live by few tenets, but they are:

THE TENETS OF SWAILING

Burn out corruption: Seek out evil and where possible burn it at the roots, so healthy lives can prosper after.
Ruthlessness: If a stretch of land must be burned to save the rest, so be it. It is your duty to carry out the sentence.
Zeal: The fire that burns in your heart is one of purity. Never lose heart in your convictions.

Channel Divinity

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

Blade of Burning Radiance By using Channel Divinity, as a bonus action you weave together threads of divine fire to create a sword of solidified radiance in your hand. This magic sword lasts until the spell ends. It counts as a simple melee weapon with which you are proficient. It deals 2d6 + CHA radiant damage on a hit. In addition, the blade sheds bright light in a 10-foot radius and dim light for an additional 10 feet.

If you drop the weapon or throw it, it dissipates at the end of the turn. Thereafter, while the spell persists, you can use a bonus action to cause the sword to reappear in your hand.

Duration: (½ Paladin Level; rounded down) minutes. (references:flame blade shadow blade)

Mercy From The Fire. As an action, by using your Channel Divinity, You instantaneously extinguish flames within your Aura of Purifying Flame. (references: Control Flames)

Oath of Devotion Spells

Aura of Purifying Flame

Starting at 7 level, during your turn, friendly creatures within 10 ft. are immune to radiant damage, When a creature within 10 feet would take fire damage from a spell cast by you, it is converted to radiant damage.

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

Purity of Flame

At 15 Level you gain Fire resistance and advantage on saves against spells dealing fire damage cast by undead and fiends. If a celestial sees fit to strike you with flame, you have disadvantage against that spell or effect and your fire resistance is nullified for 1 round.

 

Burning Soul

At 20 level You can empower the burning flame in your soul. As a Bonus Action, you gain the following benefits for 1 minute:

• If you force a creature that is not a celestial to make a saving throw to take half damage from fire or radiant damage, that creature has disadvantage.
• When you deal fire or radiant damage, it deals damage with one die larger. E.g. a d8 will become a d10, a d12 will become d12 + your Charisma Modifier.
• Once on each of your turns when you make a weapon Attack and miss, you can cause that Attack to hit instead.

Once you use this feature, your fire resistance is nullified and you can't use it again until you finish a Long Rest. You also gain 1 level of exhaustion.
