Asterios VI, King of Crete

Seductive Aura. The first time a creature enters a space within 30 ft of the paladin or starts its turn there, the paladin can force it to make a DC 16 Charisma saving throw. On a failure it is magically charmed until the beginning of the paladin's next turn, until it takes any damage, or is more than 30 ft away from the paladin.

Spellcasting. The paladin is an 18th level spellcaster (+ 8 to hit with spell attacks, spell save DC 15). Charisma is its spellcasting ability. It has the following paladin spells prepared:

1st-2nd level (Recharge 3-6 /ea): command, compelled duel*, warding bond, zone of truth
3rd-4th level (Recharge 4-6 /ea): aura of vitality*, spirit guardians*, banishment*, guardian of faith
5th level (Recharge 6/ea): circle of power*, geas

*Requires concentration

Cleansing Touch (3/day). As a bonus action, the paladin ends one spell on itself or another creature it touches.

Goring Rush. If the minotaur moves at least 20 ft straight toward a creature, it can make a horn attack against that creature as a bonus action.

Magic Items. Asterios wields the Net of Adulation

Multiattack. Asterios makes two melee attacks.

Spear. Melee or Ranged Weapon Attack: +7 to hit, reach 5 ft. and range 20/60 ft., one target. Hit: 7 (1d6 + 4) piercing damage and 4 (1d8) radiant damage.

Shield Bash. Melee Weapon Attack: +7 to hit, reach 5 ft., one creature. Hit: 6 (1d4 + 4) bludgeoning damage and 4 (1d8) radiant damage. If the target is a Medium or smaller creature, it must succeed on a DC 15 Strength saving throw or be knocked prone.

Horns. Melee Weapon Attack: +7 to hit, reach 5 ft., one creature. Hit: 7 (1d6+4) piercing damage. If the target is Large or smaller, it must succeed on a DC 15 Strength saving throw or be either pushed 10 ft straight back or knocked prone (minotaur's choice).

Net of Adulation. Ranged Weapon Attack: +10 to hit, range 5/15, two adjacent creatures. Hit: A Large or smaller creature is restrained. A creature can use its action to make a DC 13 Strength check, freeing itself or another creature within its reach on a success. The net is immune to all damage. In addition, a creature restrained by the net must succeed on a DC 20 Charisma saving throw or be magically charmed. While charmed in this way a creature must spend its turn extolling the virtues of each creature it can see within 60 ft. Charmed creatures can repeat the saving throw at the beginning of each of their turns, ending the effect on a success. 

Parry. The gladiator adds 3 to its AC against one melee attack that would hit it. To do so, the gladiator must see the attacker and be wielding a melee weapon.
