Automaton Type-Ω “Grand Strategos”

Absolute Command. All Mechanus constructs within 5 miles of the Grand Strategos gain a +3 bonus to attack rolls, saving throws, and ability checks. They cannot be frightened or charmed while within this range.

Strategic Omniscience. The Strategos can never be surprised, and all initiative rolls are made with advantage. On initiative rolls, it always acts on 30 unless another creature also rolls 30 — then it acts first.

Perfect Logic. Any effect that relies on illusion, deception, or chaos magic automatically fails against the Strategos. Chaotic creatures have disadvantage on all saves against its abilities.

Legendary Resistance (5/Day). If the Strategos fails a saving throw, it can choose to succeed instead.

Spellcasting. The Grand Strategos is a 20th-level spellcaster. Its spellcasting ability is Intelligence (spell save DC 25, +17 to hit with spell attacks). It can cast spells without material components.

Prepared Spells:

• Cantrips (at will): mage hand, minor illusion, guidance, fire bolt, [spells]thaumaturgy[/spells]

• 1st–5th (4 slots each): counterspell, dispel magic, hold monster, synaptic static, wall of force

• 6th (3 slots): globe of invulnerability, mass suggestion, true seeing

• 7th (3 slots): forcecage, reverse gravity, plane shift

• 8th (2 slots): mind blank, power word stun

• 9th (2 slots): power word kill, wish (only to replicate spells or issue divine orders through Mechanus)

Multiattack. The Strategos makes three Harmonic Disruptor Staff attacks or uses a spell.

Harmonic Disruptor Staff. Melee Weapon Attack: +13 to hit, reach 10 ft., one target. Hit: 25 (4d10 + 7) force damage plus 18 (4d8) radiant damage.

Tactical Overload (Recharge 5–6). The Strategos sends a wave of data bursts across Mechanus frequencies. Each enemy creature of its choice within 120 ft. must make a DC 25 Intelligence saving throw. On a failed save, they take 63 (14d8) psychic damage and are stunned until the end of their next turn. On a success, they take half damage and are not stunned.

Perfect Command (1/Day). The Strategos selects up to 50 constructs under its command within 1 mile. Those constructs immediately act as if they had their turn — moving and attacking as directed.

Harmonic War Network. The Strategos can communicate telepathically with all constructs under its command regardless of distance, granting them coordinated attack formations. As a bonus action, it can issue one of the following commands to up to 20 constructs:

• Advance (move and attack)

• Defend (gain +2 AC and advantage on saves)

• Focus Fire (advantage on attacks against a chosen target)

• Perfect Harmony (each construct may take one additional attack this turn)

Supreme Calculation. The Strategos can use a reaction to force a reroll of any attack roll, saving throw, or ability check made within 120 ft. It can do this 5 times per long rest.

Legendary Actions (3 per round)

• Tactical Directive. One allied construct within 120 ft. makes an attack or moves up to its speed.

• Cognitive Counter. The Strategos forces a creature it can see to reroll a successful attack roll or saving throw.

• Harmonic Pulse (Costs 2 Actions). Each enemy within 30 ft. must succeed on a DC 22 Constitution saving throw or take 27 (6d8) radiant damage and be pushed 20 ft.

• Command Recalibration (Costs 3 Actions). All allied constructs within 120 ft. regain 30 hit points and can immediately reroll one failed saving throw.
