Agamemnon of Levistus, right hand of Akmenos

Legacy of Stygia. Agamemnon knows the ray of frost cantrip and can cast armor of Agathys spell as a 2nd-level spell and darkness once per day. Charisma is his spellcasting ability for these spells.

Infernal Constitution. Agamemnon has resistance to fire, cold and poison damage.

Path of Levistus. Agamemnon magically teleports to a location of Levistus's choice within 1 mile of its location. Using this ability also restores all of Agamemnon's hit points. This ability can be invoked as an action or when Agamemnon would die. Once Agamemnon uses it, he can't use it again.

Sneak Attack. Once per turn, Agamemnon deals an extra 7d6 damage to one creature he hits with an attack if he has advantage on the attack roll. The attack must use a finesse or a ranged weapon. He doesn’t need advantage on the attack roll if another enemy of the target is within 5 feet of it, that enemy isn’t incapacitated, and he doesn’t have disadvantage on the attack roll.

Evasion. When subjected to an effect that allows him to make a Dexterity saving throw to take only half damage, Agamemnon takes instead no damage if he succeeds on the saving throw, and only half damage if he fails.

Multiattack. Agamemnon makes three scimitar attacks.

Scimitar. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 18 (3d6+4) slashing damage.

Cunning Action. Agamemnon can take a bonus action on each of his turns to Dash, Disengage, or Hide.

Master of Tactics. Agamemnon can use the Help action as a bonus action. Additionally, when he uses the Help action to aid an ally in attacking a creature, the target of that attack can be within 30 feet of him, rather than within 5 feet, if the target can see or hear him.

Parry. Agamemnon adds 4 to its AC against one melee attack that would hit it. To do so, he must see the attacker and be wielding a melee weapon.

Uncanny Dodge. When an attacker that Agamemnon can see hits him with an attack, he can use his reaction to halve the attack’s damage.

Misdirection. When Agamemnon is targeted by an attack while a creature within 5 feet of him is granting him cover against that attack, he can use his reaction to have the attack target that creature instead of him.
