Laser (Recharge 5-6): The Machanical One charges his laser and focuses in a single direction, using a full turn to do so. During the start or end, depending of what was picked, of its next turn, The Machanical One fires a red streak in a 100ft long, 5ft wide line. The laser has a pool of 325 (50d12) 50d12 fire damage. The laser goes through all creatures and objects in this line, dealing damage to them, subtracting from the pool the amount of damage dealt. The line can end short if it deals all its damage before reaching 100ft. A creature who falls to 0hp by this attack can not fall below 0 and is not killed outright. They take a death save fail. Objects that fall to 0hp are destroyed.
Indestructible: The Machanical One's tough body makes it harder to destroy. If a single attack does not do more than 25 damage to it, The Machanical One will not drop to 0 hp, an instead drop to 1hp.
Multiattack: The The Machanical One makes two iron claw attacks.
Iron Claw: Melee Weapon Attack: +7 to hit, reach 15 ft., one target. Hit: 17 (2d12 + 4) 2d12+4 bludgeoning damage.
Blast: Ranged Spell Attack: +8 to hit, range 60/120 ft., one target. Hit: 22 (5d6 + 5) 5d6+5 fire damage.
Old Machinery: The Machanical One's ancient body starts to leak miasma. All creatures within 10ft of The Machanical One must pass a DC 16 CON save. On a fail, they take 44 (8d10) 8d10 poison damage. On a pass they take half. A creature that does not need to breath is immune to this attack.
Absorption: The Machanical One creates a kinetic barrier around itself. When it does this, it can not take any actions until the end of its next turn. Any attack made against it during this time deals no damage, and instead heals The Machanical One for 10 (1d20) 1d20 per attack made.
Reactive: The The Machanical One can take one reaction on every turn in combat.
Stun: When hit by an attack, The Machanical One discharges a current of electricity. The attacker must make a DC 18 CON save. On a fail, the creature is stunned until the end of its next turn.
Sturdy: As a reaction to a creature attacking it, The Machanical One can raise its AC by +3 for the attack.
