Balthazar

Skills - 

Aura of Hate - You, as well any fiends and undead within 10 feet of you, gain a +3 bonus to melee weapon damage rolls. A creature can benefit from this feature from only one paladin at a time.

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 × 5.

Channel Divinity: Control Undead - As an action, you target one 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 24 hours, 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.

Channel Divinity: Dreadful Aspect - Each creature of your choice within 30 feet of you must make a Wisdom saving throw if it can see you. On a failed save, the target is frightened of you for 1 minute. If a creature frightened by this effect ends its turn more than 30 feet away from you, it can attempt another Wisdom saving throw to end the effect on it.

Lord of The Scourge - When you reduce a creature to 0 hit points with Frost Bite, you can spend 2 hit dice to summon them as a zombie or skeleton

Turasjir di Whedabra (Book of Darkness in Draconic) - 
Any melee spell attack you make with the hand, and any melee weapon attack made with a weapon held by it, deals an extra 2d8 cold damage on a hit.
