Oath of the Ronin

Mostly Reskin of Oath of Devotion fittet to suit a Fiendish Samurai Belief, changed Casting Ability to Int because the members in my lore are more on the hardened philiosophical side. Also a very experimental very anime 20th level ability.

Channel Divinity

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

Determined Weapon. As an action, you can imbue one weapon that you are holding with determined energy, using your Channel Divinity. For 1 minute, you add your Intelligence modifier to attack rolls made with that weapon (with a minimum bonus of +1). The weapon also emits bright light in a 20-foot radius and dim light 20 feet beyond that. If the weapon is not already magical, it becomes magical for the duration.

You can end this effect on your turn as part of any other action. If you are no longer holding or carrying this weapon, or if you fall unconscious, this effect ends.

Fiendish Authority. As an action, you present your symbol of belief and speak a prayer censuring celestial and undead, using your Channel Divinity. Each celestial or undead that can see or hear you within 30 feet of you must make a Wisdom saving throw. If the creature fails its saving throw, it 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.

Oath Spells

You gain oath spells at the paladin levels listed.

Oath of Devotion Spells

Aura of Devotion

Starting at 7th level, you and friendly creatures within 10 feet of you can’t be charmed while you are conscious.

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

Purity of Spirit

Beginning at 15th level, you are always under the effects of a protection from evil and good spell.

Truest Strike

At 20th level, as a bonus action, you can choose one enemy. You both make a opposed determination check (flat roll). You both may add a bonus to the roll by sacrificing a equal amount of full hit dice of hp. So for example if your hit die is a d8, you have to forgo 8hp for a +1 on the roll.

The winner of the determination check gains the following effect on the next attack against the loser: You crit and do max damage on the attack.

This ability recharges after a long rest.
