Racial:
-Darkvision. Thanks to your infernal heritage, you have superior vision in dark and dim conditions. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern color in darkness, only shades of gray.
-Hellish Resistance. You have resistance to fire damage.
-Legacy of Avernus. You know the Thaumaturgy cantrip. Once you reach 3rd level, you can cast the Searing Smite spell once as a 2nd-level spell. Once you reach 5th level, you can also cast the Branding Smite spell once as a 3rd-level spell. You must finish a long rest to cast these spells again with this trait. Charisma is your spellcasting ability for these spells.

Feats:
*Polearm Master
-When you take the Attack action and attack with only a glaive, halberd, quarterstaff, or spear, you can use a bonus action to make a melee attack with the opposite end of the weapon. This attack uses the same ability modifier as the primary attack. The weapon's damage die for this attack is a d4, and it deals bludgeoning damage.
-While you are wielding a glaive, halberd, pike, quarterstaff, or spear, other creatures provoke an opportunity attack from you when they enter the reach you have with that weapon.

*Spear Mastery
-You gain a +1 bonus to attack rolls you make with a spear.
-When you use a spear, its damage die changes from a d6 to a d8, and from a d8 to a d10 when wielded with two hands. (This benefit has no effect if another feature has already improved the weapon’s die.)
-You can set your spear to receive a charge. As a bonus action, choose a creature you can see that is at least 20 feet away from you. If that creatures moves within your spear’s reach on its next turn, you can make a melee attack against it with your spear as a reaction. If the attack hits, the target takes an extra 1d8 piercing damage, or an extra 1d10 piercing damage if you wield the spear with two hands. You can’t use this ability if the creature used the Disengage action before moving.
-As a bonus action on your turn, you can increase your reach with a spear by 5 feet for the rest of your turn.

*Mounted Combatant
-You have advantage on melee attack rolls against any unmounted creature that is smaller than your mount.
-You can force an attack targeted at your mount to target you instead.
-If your mount is subjected to an effect that allows it to make Dexterity saving throw to take only half damage, it instead takes no damage if it succeeds on the saving throw, and only half damage if it fails.

Class:
*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.

*Dueling
-When you are wielding a melee weapon in one hand and no other weapons, you gain a +2 bonus to damage rolls with that weapon.

*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.

*Channel Divinity
-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

*Harness Divine Power
-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.

*Aura of Protection
-Starting at 6th level, whenever you or a friendly creature within 10 feet of you must make a saving throw, the creature gains a bonus to the saving throw equal to your Charisma modifier (with a minimum bonus of +1). You must be conscious to grant this bonus. At 18th level, the range of this aura increases to 30 feet.

*Relentless Avenger
-By 7th level, your supernatural focus helps you close off a foe's retreat. When you hit a creature with an opportunity attack, you can move up to half your speed immediately after the attack and as part of the same reaction. This movement doesn't provoke opportunity attacks.

*Aura of Courage
-Starting at 10th level, you and friendly creatures within 10 feet of you can't be frightened while you are conscious.At 18th level, the range of this aura increases to 30 feet.

*Improved Divine Smite
-By 11th level, you are so suffused with righteous might that all your melee weapon strikes carry divine power with them. Whenever you hit a creature with a melee weapon, the creature takes an extra 1d8 radiant damage.
