Oath of the Blackguard

Tenets of the oath 

A paladin who embraces the Oath of the Blackguard owes allegiance to no one. There are no tenets of this oath, for it lacks any substance.

Those who are unfortunate enough to have close contact with blackguards have observed that blackguard's overwhelming concern is burning power, especially if it can be obtained at the expense of others.

Channel Divinity

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

Smite Good.  As part of making an attack, you can decide to smite good, if the creature’s alignment is other than Evil, you gain a bonus to the attack roll and damage roll equal to your charisma modifier and can add an additional number of necrotic damage equal to your paladin level. You can use this ability after seeing the roll but before knowing whether it hits or not.

Command Fiend and Undead. As an action, you target one fiend or undead creature you can see within 30 feet of you. The target must make a Wisdom saving throw. On a failed save, the target must obey your commands for the next hour, or until you use this channel divinity option again. An undead whose challenge rating is equal to or greater than your paladin level is immune to this effect. You need to concentrate on this effect as if you were concentrating on a spell.

Draining Smite

Embodiment of Death

 As a bonus action, for one minute you can unleash the full might and power of the blackguard’s oath.

.Your aura of despair ability now reduces the saving throws and armor class of enemies by 4. In addition the aura reduces any bright light in a 30-foot radius around you to dim light. Enemies that start their turn in your aura must succeed a Wisdom saving throw(DC {{savedc:cha}}) or be frightened of you for 1 minute. While active, you have advantage on attack rolls against creatures that are frightened of you
