Destroyer

Undead Commander. As a bonus action, the destroyer commands an undead ally within 30 feet of it to use a reaction to make one attack against a creature the destroyer attacked this round.

Void Strength. The destroyer has advantage on Wisdom (Perception) checks and on saving throws against being blinded, charmed, deafened, frightened, stunned, and knocked unconscious.

Void Weapons. The satarre's weapon attacks are magical. When the satarre hits with any weapon, the weapon deals an extra 1d8 necrotic damage (included in the attack).

Multiattack. The satarre destroyer makes two attacks: one with its greataxe and one with its claw.

Claw. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) piercing damage plus 4 (1d8) necrotic damage.

Greataxe. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 9 (1d12 + 3) slashing damage plus 4 (1d8) necrotic damage. If the target is a Medium or smaller creature, it must succeed on a DC 13 Strength saving throw or be knocked prone.

Spear. Melee or Ranged Weapon Attack: +5 to hit, reach 5 ft. or range 20/60 ft., one target. Hit: 6 (1d6 + 3) piercing damage, or 7 (1d8 + 3) piercing damage if used with two hands to make a melee attack.
