From D&D Wiki
Huge construct, unaligned
Saving Throws Con +17, Int +9, Wis +10
Legendary Resistance (3/Day). If Omega fails a saving throw, it can choose to succeed instead.
Magic Resistance. Omega has advantage on saving throws against spells and other magical effects.
Immutable Form. Omega is immune to any spell or effect that would alter its form.
Magic Weapons. Omega’s weapon attacks are magical.
Siege Monster. Omega deals double damage to objects and structures.
Multiattack. Omega can use its Targeting Laser. It then makes four attacks: two with its claws and two with its ray, or four with its ray.
Claw. Melee Weapon Attack: +16 to hit, reach 10 ft., one target. Hit: 21 (3d8 + 8) slashing damage.
Ray. Ranged Spell Attack: +10 to hit, range 120 ft., one target. Hit: 22 (5d8) radiant damage.
Targeting Laser. Omega targets one creature that it can see within 120 feet of it. The target becomes marked, giving Omega advantage on all attack rolls made against it and the target has disadvantage on all saving throws made against effects caused by Omega. If the target moves further than 120 feet away from Omega or if Omega cannot see the target, the effect ends.
Missile Barrage. Omega fires four rockets, each of which is aimed at a single target Omega can see within 120 feet of it. The target and all creatures within a 15 feet of it must make a DC 17 Dexterity saving throw, taking 22 (4d10) fire damage on a failed save, or half as much damage on a successful one.
Wave Cannon (Recharge 5-6). Omega fires high-intensity particle streams in a 90-foot cone. Each creature in that area must make a DC 25 Dexterity saving throw, taking 98 (28d6) force damage on a failed save, or half as much on a successful one.
The Omega can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. The Omega regains spent legendary actions at the start of its turn.
Attack. Omega makes one claw attack or ray attack.
Missile Barrage (Costs 2 Actions). Omega uses its Missile Barrage.
Repulsor Field (Costs 3 Actions). Omega generates a field of concussive force to repel enemies. All creatures within 30 feet of Omega must make a DC 25 Constitution saving throw. A creature that fails its saving throw takes 39 (7d10) thunder damage and is stunned until the end of its next turn. A creature that succeeds on its saving throw the target takes half as much damage and isn’t stunned. Targets are pushed up to 20 feet away from Omega regardless of saving throw results.
Omega is a fearsome war machine created by a long-dead civilization. It traverses the planes seemingly at random, tirelessly carrying out the last command it ever received from its masters: to avenge their destruction.
Magitech Menace. Omega was created through a fusion of powerful magic and highly-advanced technology. While superficially similar to a golem, its complexity is of an entirely different level. It is a perpetual motion machine, self-sustaining and self-repairing, able to fabricate ammunition for its missile pods seemingly from thin air. Omega’s magitech nature also allows it to plane shift, see through illusions and invisibility, and harm supernatural beings that would shrug off mundane weapons.
Death Machine. Omega carries an impressive arsenal within its spider-like frame. In addition to its massive claws, the machine sports ray guns, incendiary missile pods, a repulsor field generator, and a terrifying “wave cannon” that unleashes torrents of unfathomable energy. Its destructive power is second only to that of the tarrasque.
Single-Minded. Omega is a soulless machine. It has no concept of ethics or morality. All it cares about is fulfilling its programming, and it is content to ignore most beings so long as they don’t get in its way. Should anyone or anything impede its task, Omega will not hesitate to annihilate them. That said, its mission and self-preservation take precedence; in the rare event that it should find itself in danger of being destroyed, Omega will flee rather than continue to fight a losing battle.
Efficient Eradicator. When attacked, Omega seeks to destroy its opponents as quickly and efficiently as possible. Its preferred strategy is to mark one creature with its targeting laser and obliterate it with a focused salvo of ray attacks, shifting targets only when the first one is destroyed. If surrounded by multiple enemies it will attempt to daze them with its repulsor field, then back up enough to hit as many of them as possible with a deadly wave cannon blast. If its foes are too spread out for that, it will instead bombard them with missiles.
