Bellumarch Sovereign

Acheronic Incarnation. The bellumarch exists in constant gravitational flux. Difficult terrain does not affect it, and ranged attacks against it are made with disadvantage within 30 feet due to warping space.

Sibling of the Cosmic Pantheon. The bellumarch always knows the direction and distance to all other siblings if they are on the same plane.

War-Mind Supreme. All hostile creatures within 60 feet have disadvantage on Intelligence, Wisdom, and Charisma saving throws as their thoughts are overwhelmed by battlefield logic and domination pressure.

Aura of Subjugation. Hostile creatures that start their turn within 20 feet must succeed on a DC 23 Wisdom saving throw or be frightened and restrained until the end of their next turn.

Endless Conquest Protocol. When a hostile creature drops to 0 hit points within 60 feet, the bellumarch gains 20 temporary hit points and can immediately move up to half its speed.

Legendary Resistance (3/ Day, or 4 in Lair). If the bellumarch fails a saving throw, it can choose to succeed instead.

Multiattack. The bellumarch makes three attacks: one horned gore, one claw, and one crushing strike.

Horned Gore (Argali Crown). Melee Weapon Attack: +16 to hit, reach 10 ft., one target. Hit: 36 (4d12 + 9) piercing damage plus 18 (4d8) force damage.

Claw (Lion Talons). Melee Weapon Attack: +16 to hit, reach 5 ft., one target. Hit: 32 (4d10 + 9) slashing damage.

Crushing Strike (Jackal Execution). Melee Weapon Attack: +16 to hit, reach 10 ft., one target. Hit: 34 (4d10 + 9) bludgeoning damage, and the target must succeed on a DC 23 Constitution saving throw or have its speed reduced to 0 and be stunned until the end of its next turn.

Cataclysmic Command (Recharge 5–6). The bellumarch releases a war-decree pulse in a 60-foot radius. Each hostile creature must make a DC 23 Wisdom saving throw. On a failure: 63 (14d8) psychic + force damage and the creature is dominated (as dominate monster) until the end of its next turn. On a success: Half damage and not dominated.

Mark of Dominion. One creature the bellumarch can see within 60 feet is marked for conquest for 1 minute:

• The bellumarch has advantage on attacks against it

• The target has disadvantage on saving throws

• The target’s movement speed is halved

• If the target drops to 0 HP, it cannot be revived for 1 minute without divine magic

Imperial Override. When the bellumarch is targeted by a spell, it can force the caster to succeed on a DC 23 Intelligence saving throw or the spell fails and the caster takes 18 (4d8) psychic damage.

The bellumarch can take 3 (4 in Lair) legendary actions, choosing from the options below.

Conquest Step. Move up to 30 feet.

Sovereign Strike. Make one claw or gore attack.

War Protocol (Costs 2 Actions). All hostile creatures within 30 feet must succeed on a DC 23 Wisdom saving throw or be frightened and have disadvantage on attack rolls until the end of their next turn.
