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).
As an action, the paladin channels the darkest emotions and focuses them into a burst of magical menace. Each creature of the paladin's choice within 30 feet of the paladin must make a Wisdom saving throw if it can see the paladin. On a failed save, the target is frightened of the paladin for 1 minute. If a creature frightened by this effect ends its turn more than 30 feet away from the paladin, it can attempt another Wisdom saving throw to end the effect on it.
As an action, the paladin targets one undead creature he or she can see within 30 feet of him or her. The target must make a Wisdom saving throw. On a failed save, the target must obey the paladin's commands for the next 24 hours, or until the paladin uses this Channel Divinity option again. An undead whose challenge rating is equal to or greater than the paladin's level is immune to this effect.
The target takes an extra 2d8 Radiant damage from the attack. The damage increases by 1d8 if the target is a Fiend or an Undead.
Using a Higher-Level Spell Slot. The damage increases by 1d8 for each spell slot level above 1.
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 × 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.
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 temporarily remember glimpses of the past, perhaps faded memories from ages ago or a previous life.
When you make an ability check that uses a skill, you can roll a d6 immediately after seeing the number on the d20 and add the number on the d6 to the check. You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
