Feature: Avian Scout

As a Falconer, you can employ the capture, use, and companionship of a bird of prey. You can spend your downtime to train a bird of prey to perform special tricks, beyond the usual techniques of hunting and returning. Each trick takes 10 days of downtime.
Perfect Return: The bird will return to you when called regardless of other distractions.
Follow: You can use a bonus action to direct your bird to follow one creature you point to. You can track your bird by listening for its bell or spotting its tassel.
Distract: You can use a bonus action to direct your bird to distract a creature you point to. On its turn, the bird will fly to the target and take the Help action to distract the target each turn until you call it to return.

Divine Sense

The presence of strong evil registers on your senses like a noxious odor, and powerful good rings like heavenly music in your ears. As an action, you can open your awareness to detect such forces. Until the end of your next turn, you know the location of any celestial, fiend, or undead within 60 feet of you that is not behind total cover. You know the type (celestial, fiend, or undead) of any being whose presence you sense, but not its identity (the vampire Count Strahd von Zarovich, for instance). Within the same radius, you also detect the presence of any place or object that has been consecrated or desecrated, as with the Hallow spell.

You can use this feature a number of times equal to 1 + your Charisma modifier. When you finish a long rest, you regain all expended uses.

Lay on Hands

Your blessed touch can heal wounds. You have a pool of healing power that replenishes when you take a long rest. With that pool, you can restore a total number of hit points equal to your paladin level x 5.

As an action, you can touch a creature and draw power from the pool to restore a number of hit points to that creature, up to the maximum amount remaining in your pool.

Alternatively, you can expend 5 hit points from your pool of healing to cure the target of one disease or neutralize one poison affecting it. You can cure multiple diseases and neutralize multiple poisons with a single use of Lay on Hands, expending hit points separately for each one.

This feature has no effect on undead and constructs.

Fighting Style

Starting at 2nd level, you adopt a particular style of fighting as your specialty. Choose one of the following options. You can't take a Fighting Style option more than once, even if you later get to choose again.

Protection.

When a creature you can see attacks a target other than you that is within 5 feet of you, you can use your reaction to impose disadvantage on the attack roll. You must be wielding a shield.

Divine Smite

Starting at 2nd level, when you hit a creature with a melee weapon attack, you can expend one spell slot to deal radiant damage to the target, in addition to the weapon's damage. The extra damage is 2d8 for a 1st-level spell slot, plus 1d8 for each spell level higher than 1st, to a maximum of 5d8. The damage increases by 1d8 if the target is an undead or a fiend, to a maximum of 6d8.

Divine Health

By 3rd level, the divine magic flowing through you makes you immune to disease.

Sacred Oath

When you reach 3rd level, you swear the oath that binds you as a paladin forever. Up to this time you have been in a preparatory stage, committed to the path but not yet sworn to it. Your choice grants you features at 3rd level and again at 7th, 15th, and 20th level. Those features include oath spells and the Channel Divinity feature.

Harness Divine Power (Optional)

Also at 3rd level, you can expend a use of your Channel Divinity to fuel your spells. As a bonus action, you touch your holy symbol, utter a prayer, and regain one expended spell slot, the level of which can be no higher than half your proficiency bonus (rounded up). The number of times you can use this feature is based on the level you've reached in this class: 3rd level, once; 7th level, twice; and 15th level, thrice. You regain all expended uses when you finish a long rest.

Extra Attack

Beginning at 5th level, you can attack twice, instead of once, whenever you take the Attack action on your turn.

Tenets of Vengeance

The tenets of the Oath of Vengeance vary by paladin, but all the tenets revolve around punishing wrongdoers by any means necessary. Paladins who uphold these tenets are willing to sacrifice even their own righteousness to mete out justice upon those who do evil, so the paladins are often neutral or lawful neutral in alignment. The core principles of the tenets are brutally simple.

Fight the Greater Evil. Faced with a choice of fighting my sworn foes or combating a lesser evil, I choose the greater evil.

No Mercy for the Wicked. Ordinary foes might win my mercy, but my sworn enemies do not.

By Any Means Necessary. My qualms can't get in the way of exterminating my foes.

Restitution. If my foes wreak ruin on the world, it is because I failed to stop them. I must help those harmed by their misdeeds.

Channel Divinity

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

Abjure Enemy.

As an action, you present your holy symbol and speak a prayer of denunciation, using your Channel Divinity. Choose one creature within 60 feet of you that you can see. That creature must make a Wisdom saving throw, unless it is immune to being frightened. Fiends and undead have disadvantage on this saving throw.

On a failed save, the creature is frightened for 1 minute or until it takes any damage. While frightened, the creature's speed is 0, and it can't benefit from any bonus to its speed.

On a successful save, the creature's speed is halved for 1 minute or until the creature takes any damage.

Vow of Enmity.

As a bonus action, you can utter a vow of enmity against a creature you can see within 10 feet of you, using your Channel Divinity. You gain advantage on attack rolls against the creature for 1 minute or until it drops to 0 hit points or falls unconscious.
