Armorer's Animated Armor(Legendary)

Antimagic Susceptibility. The armor is incapacitated while in the area of an antimagic field. If targeted by dispel magic, the armor must succeed on a Constitution saving throw against the caster's spell save DC or fall unconscious for 1 minute. However at the end of each of its turns it can repeat the save to reboot and regain consciousness.

Magic Resistance. The armor has advantage on saving throws against spells and other magical effects.

Spell Absorption. The armor is immune to the spells fireball, lightning bolt, and disintegrate. If struck by any of these spells, the armor recovers Hit points in a number of d6s equal to the level of the spell slot spent to cast the spell.

False Appearance. While the armor remains motionless, it is indistinguishable from a normal suit of armor.

Defensive Field. As a bonus action, the armor can gain 20 temporary hit points, replacing any temporary hit points it already has. It can be used 6 times per long rest.

Dampening Field. The armor has advantage on Dexterity (Stealth) checks.

Armorer's Bond. If the mending spell is cast on it, it regains 4d6 hit points. If it has died within the last hour, you can use your smith’s tools as an action to revive it, provided you are within 5 feet of it and you expend a spell slot of 1st level or higher. The armor returns to life after 1 minute with all its hit points restored.

Sentinel. The armor has the Sentinel feat.

Damage Reduction. All bludgeoning, piercing, and slashing damage that the armor takes is reduced by 3.

Armored Cage. If the armor lands a slam or Thunder gauntlet attack, the armor will attempt to capture and incapacitate its target within. (Escape DC 26) On the end of the captured target's turn they can attempt to escape again. While the target is captured, it takes half of any damage that the armor receives. On each of the armor's turns, it can release its captive as a free action, or as a bonus action it can sap the energy from the captive to restore its own. The target can make a CON save(DC 23) to resist the effect. On a failed save, the target takes 14 (4d6) psychic damage and the armor restores HP equal to then amount of damage dealt.

Taking Prisoners (Recharge 3-6). Even while the Armor's Armored Cage is occupied, it is capable of capturing multiple targets at once as it releases up to four extending mechanical tendrils from its body. Each tendril can be attacked (AC 20; 10 hit points; immunity to poison and psychic damage, an adamantine in build). Destroying a tendril deals no damage to the armor. A tendril can also be broken if a creature takes an action and succeeds on a DC 20 Strength check against it. If a tendril is broken, the metal broken seems to liquefy. Over time, the tendrils will self-repair, but each tendril recharges on its own time.

Innate Spellcasting. The Armor can cast spells using its Intelligence as it's Spellcasting modifier. (12th level spellcaster DC 23)

Last Resort(1/day). If the armor is incapacitated but not destroyed and a spell 6th level or lower is cast within 30', it can capture that spell's energy to revive itself. If it does so, the armor recovers Hit points in a number of d6s equal to the level of the spell slot spent to cast the spell.
