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.
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.
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.
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.
You are immune to disease.
As an action, you present your holy symbol and speak a prayer o f 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.
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.
You can attack twice, instead of once, whenever you take the Attack action on your turn.
