Oath of Betrothal

Each paladin who takes the Oath of Betrothal has a beloved to whom their heart belongs, and it is to this person they direct and swear their oath. Consider with your DM who your beloved is and how they relate to the campaign. Does the person you love live in your hometown, waiting for you to safely return someday? Do you quest in order to rescue them from an evil that has taken them captive? Do you actively travel with the one with whom you are besotted? It can also be useful to think about what your beloved thinks of your choice to adventure. Do they approve of such heroics? Condemn you for risking your life? 

Channel Divinity

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

Confess Love. Your loving declaration thunders with power from the depths of your heart. You can use your Channel Divinity as an action to invoke the name of your beloved, which is audible out to 100 feet. You gain temporary hit points equal to your paladin level, and one creature of your choice within 30 feet of you that can hear you must make a Strength saving throw. On a failed save, it is knocked prone and takes thunder damage equal to 1d6 + your paladin level. On a successful save, the creature takes half as much damage and isn't knocked prone.

To be True. When you or a creature within 30 feet of you fails a saving throw against an enchantment spell or against being charmed, you can use your reaction to speak a prayer of virtue, using your Channel Divinity. The affected creature rerolls the saving throw with advantage, possibly changing the failure to a success.

Oath of Devotion Spells

Aura of Care

Starting at 7th level, at the start of each of your turns while you aren't incapacitated, you can choose to lose hit points up to your paladin level, converting your vitality into healing energy that can restore hit points equal to those you lost. Choose any number of conscious creatures within 10 feet of you, and distribute those hit points among them. You can't use this feature on undead or constructs.

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

Constancy of Heart

Beginning at 15th level, the integrity of your love is unmarred. You can't be affected by any enchantment spell unless you choose to be.

Holy Romantic

At 20th level, you can use your action to draw upon your love to aid you in battle, placing you in danger before others. Your heart visibly glows with burning light, as though searing your flesh, and for 1 minute, you gain the following benefits:

--You shed bright light in a 15-foot radius and dim light for an additional 15 feet.

--Hostile creatures within 30 feet of you have disadvantage on all attack rolls made against any creature besides you.

--When you roll a 1 or 2 on a damage die, you can reroll the die and must use the new roll.

--When a friendly creature you can see takes damage, you can move up to your speed toward it as a reaction.

--You are immune to being charmed.
