Cadogan

Break Will. Cadogan has a pool of power that can restore or hinder up to 45 hit points. As a full action, he can touch a creature and draw power from this pool to restore a number of hit points to that creature, up to the max remaining in his pool. Alternatively, he may make a melee attack (+7 to hit) to touch an enemy and inflict psychic damage, up to the max remaining in his pool. This pool replenishes after a long rest. 

Vicious Smite. When Cadogan hits a creature with a melee weapon attack, he can expend one spell slot to deal necrotic 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. 

Great Weapon Master. Before Cadogan makes a melee attack with a heavy weapon, he can choose to take a -5 penalty to hit to add +10 to the attack's damage. 

Dreadful Aspect. As an action, the Cadogan 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 (DC 15) 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. This may be used once per short or long rest. 

Aura of Despair. Any enemy creature within 10 feet of Cadogan that is required to make a saving throw is required to subtract Cadogan's Charisma modifier (-3) from the result. Cadogan must be conscious to create this effect.
