Alan Ebonhardt, Fallen Angel of Malkizid

Essence of the Titan (Mythic Trait). If Thrumsh is reduced to 0 HP, Alan heals to his max HP and immediately moves to Thrumsh's side without provoking Opportunity Attacks. He encircles Thrumsh with holy hellfire, taking his Blood Moon Blade and the brutality of his eternal rage. 

Revelation of the Hells. Alan is in a permanent state of infernal transformation with two hellish wings sprouting from his back. He has a Fly speed equal to his Speed and deals an additional 2d8 radiant damage when he deals damage with any weapon attack (included in attacks).

Legendary Resistance (5/Day). Alan and Thrumsh share 5 Legendary Resistances. If Alan fails a saving throw, he can choose to succeed instead.

Combat Superiority. Alan's superiority dice are d10s. He can use this feature any number of times, but only once per turn.

• Trip Attack. When you hit a creature with an attack roll using a weapon or an Unarmed Strike, you can expend one Superiority Die and add the die to the attack’s damage roll. If the target is Large or smaller, it must succeed on a DC 17 Strength saving throw or have the Prone condition.

• Menacing Attack. When you hit a creature with an attack roll, you can expend one Superiority Die to attempt to frighten the target. Add the Superiority Die to the attack’s damage roll. The target must succeed on a DC 17 Wisdom saving throw or have the Frightened condition until the end of your next turn.

• Precision Attack. When you miss with an attack roll, you can expend one Superiority Die, roll that die, and add it to the attack roll, potentially causing the attack to hit.

• Sweeping Attack. When you hit a creature with a melee attack roll using a weapon, you can expend one Superiority Die to attempt to damage another creature. Choose any number of creatures within 5 feet of the original target and within your reach. If the original attack roll would hit the other creatures, it takes damage equal to the number you roll on your Superiority Die plus 9 (2d8) radiant damage. The damage is of the same type dealt by the original attack.

Disarming Riposte. When a creature misses you with a melee attack roll, you can take a Reaction and make a melee attack roll with a weapon against the creature. If you hit, add the Superiority Die to the attack’s damage and the target must make a DC 17 Strength saving throw. On a failure, the target drops its weapon and it falls on the ground at its feet.

Parry. When another creature damages you with a melee attack, you can use your reaction and expend one superiority die to reduce the damage by the number you roll on your superiority die + 5.
