Ancient Steel Dragon - AI-generated fantasy Monster

Ancient Steel Dragon

Ancient Steel Dragons were shaped during an era when mortal kingdoms sought to bind metallic dragons into living weapons. Most were destroyed or escaped, but a few survived by becoming guardians, advisors, and secret arbiters of civilization. This dragon remembers the first wars of iron and considers modern nations dangerously immature. It collects artifacts not for wealth, but to prevent their misuse and preserve the history of every major conflict.

Legendary Resistance. If the dragon fails a saving throw, it can choose to succeed instead. It can use this trait four times per day, or five times per day while in its lair.
Magic Weapons. The dragon's weapon attacks are magical.
Forged Mind. The dragon has advantage on saving throws against being charmed, frightened, paralyzed, or stunned.
Steel Telepathy. The dragon can communicate telepathically with any creature within 120 feet that can understand at least one language. It can also sense all unattended metal objects within 60 feet.
Furnace Aura. The dragon emits a furnace-like aura in a 15-foot radius. A creature that starts its turn in the aura while wearing or holding metal takes 5 () fire damage. The dragon can suppress or restore this aura as a bonus action.
Smoke-Bound Hunter. The dragon has advantage on Dexterity (Stealth) checks made in dim light, darkness, smoke, or industrial clutter. It can attempt to Hide while only lightly obscured by smoke or sparks.
Multiattack. The dragon makes one Bite attack and two Claw attacks.
Bite. Melee Weapon Attack: to hit, reach 15 ft., one target. Hit: 19 () piercing damage plus 7 () force damage.
Claw. Melee Weapon Attack: to hit, reach 10 ft., one target. Hit: 15 () slashing damage.
Tail. Melee Weapon Attack: to hit, reach 25 ft., one target. Hit: 17 () bludgeoning damage. If the target is a Huge or smaller creature, it is grappled, escape .
Wing Attack. The dragon beats its wings. Each creature within 15 feet of the dragon must succeed on a Dexterity saving throw or take 17 () bludgeoning damage and be knocked prone. The dragon can then fly up to half its flying speed.
Molten Steel Breath. The dragon exhales a roaring storm of incandescent metal in a 90-foot cone. Each creature in that area must make a Dexterity saving throw, taking 63 () fire and force damage on a failed save, or half as much damage on a successful one. A creature that fails the save is also blinded until the end of its next turn. The dragon can use this breath again after recharging on a roll of 5 or 6 on a d6.
Magnetic Deflection. When a creature within 60 feet makes an attack with a metal weapon or casts a spell requiring a metal focus, the dragon imposes disadvantage on the attack roll or grants the target advantage on its saving throw by magnetically deflecting the weapon or focus. The dragon can use this reaction three times per day.
Detect or Tail Attack. The dragon makes a Wisdom (Perception) check or makes one Tail attack.
Wing Attack (Costs 2 Actions). The dragon beats its wings. Each creature within 15 feet must succeed on a Dexterity saving throw or take 17 () bludgeoning damage and fall prone. The dragon can then fly up to half its flying speed.
Command Metal (Costs 2 Actions). The dragon targets one creature it can see within 60 feet. The target must succeed on a Wisdom saving throw or become frightened until the end of its next turn. A frightened target also drops one held metal object of the dragon's choice.
