Ace Barbaross, Biker of Hell

Cavalry. Opportunity attacks taken against the Ace are at disadvantage.

Weight Displacement. Attempts to knock prone or grapple Ace are made at disadvantage; if Ace must attempt to resist, its rolls are made at advantage.

Spellcasting. The Necroglaive allows Ace to cast bane once per day at level 1, with a DC of 14.

Multiattack. Ace uses either Full Throttle or Burning Wheels, if available. Ace then uses Necroglaive and Hellfire.

Necroglaive. Melee Weapon Attack: +8 to hit, reach 10 ft., 1 target. Hit: 10 (2d6 + 3) [slashing] damage plus 4 (1d6) [necrotic] damage. This attack deals an additional 4 (1d6) [slashing] damage if Ace has moved at least 20 feet during this turn.

Hellfire. Ranged Weapon Attack: +7 to hit, range 30/90 ft., 1 target. Hit: 9 (2d8) [fire] damage. If a creature hit by Hellfire has a Good alignment, they take an additional 3 (1d4) [fire] damage.

Full Throttle (Recharge 5-6). Ace revs his engines, spewing acrid smoke around him. All creatures that require breathing within a 20-foot radius must make a DC 15 [Constitution] saving throw or take 5 (2d4) acid damage and 5 (2d4) [fire] damage. If a creature fails by 5 or more, it is also stunned until either it is hit by an attack or until the beginning of Ace's next turn.

Burning Wheels (Recharge 5-6). Ace reels back and pops a wheelie, causing the front wheel to burst into flames. Any creature in a 20 ft. cone of Ace must make a DC 15 [Dexterity] saving throw or take 14 (3d8) [fire] damage and 5 (1d8) [bludgeoning] damage.

Haunting Cackle. Up to 3 undead creatures within Ace's sight who can hear Ace each gain 4 (1d6) temporary hit points. For the purpose of this instance of counting, a White Knuckle Biker Gang counts as 3 undead creatures.

Quick Exit. After being hit with an attack, Ace can move up to his speed as a reaction, provoking opportunity attacks if possible.
