Aspect of Thorril

Dwarven Turret. Thorril possesses a Medium construct of a Turret that constantly remains by his side once active, giving him two special actions described below. It has 150 hit points, AC 24, walking speed 20 ft., a 10 in all stats and is immune to psychic and poison damage. In his Gladiator Armor it mounts on its shoulder, although it can still be targeted for attacks and damaged. It exists until destroyed or until he returns it to its dormant state as a bonus action.

Fail Safe. When Thorril is slain, his body is destroyed along with any magic item or machine he had created, but in his domain an imediated fail safe is activated that puts a downloaded copy of his conscious within a cloned body. The body becomes fully functional in 1d100 days at which point Thorril becomes active again.

Innate Spellcating. Thorril can innately cast mending spell as an action, requiring no material components. If cast on a construct it restores 7 (2d6) hit points.

Legendary Resistance (5/Day). If Thorril fails a saving throw, he can choose to succeed instead.

Special Equipment. Thorril wields a magical mallet named Erupting Mallet, and wears a Belt of Stormgiant Strength, a Ring of Spell Storing, and carries a Dimensional Sash. Inside the sash he stores the Dwarven Turret, and the Guardian Armor. The Erupting Mallet is a +3 mallet.

While attuned to the ring, Thorril can, as an action, expend some of it's charges to cast heat metal or intellect fortress once each, at will, requiring no material components (save DC 21).

Tactical Assessment. Thorril targets a creature he can see within 60 feet of him, and attempts to make a Wisdom (Insight) check contested by a creatures Charisma (Deception) check. If he is successful, Thorril learns the creatures game statistics.

Multiattack. Aspect of Thorril makes one attack with his Dwarven Turret, and then he makes three weapon attacks.

Erupting Mallet. Melee or Ranged Weapon Attack: +21 to hit, reach 5 ft., or range 20/60 ft., one target. Hit: 15 (1d6 + 12) bludgeoning damage, or 21 (2d8 + 12) bludgeoning damage when he is in his Guardian Armor, plus 18 (4d8) fire damage, and 9 (2d8) force damage dealt in a 15-foot sphere as it erupts in flames. When thrown, the mallet always returns to Thorril's hand weather it hits or misses.

Force Blast (Dwarven Turret Only). Ranged Spell Attack: +18 to hit, range 120 ft., one target. Hit: 22 (4d10) force damage. If the target is a creature, it must make a DC 26 Strength saving throw or be pushed back 5 feet from the cannon.

Flamethrower (Dwarven Turret Only). The cannon exhales fire in a 15-foot cone, each creature in that area must make a DC 26 Dexterity saving throw, taking 22 (5d8) fire damage on a failed save, or half as much damage on a successful one. The fire ignites any flammable objects in the area that aren’t being worn or carried.

Detonate. Thorril presses a button on his arm and detonates one of his constructs if it is within 60 feet of him. When detonated in this way each creature within 20 feet of the construct must make a DC 24 Dexterity saving throw, taking 54 (12d8) fire damage on a failed save, or half as much damage on a successful one.

Guardian Armor (Recharges on a Long rest). Thorril summons a mechanical armor to constructs around his body. The armor attaches to him and can't be removed against his will, although it has a retractable helmet which he can retract as a bonus action. While in the armor, Thorril's base hit points become 440, his size doubles and he becomes Large, his reach increases by 5 feet, and he makes Strength checks and Strength saving throws with advantage. The armor remains until it is destroyed, or he dismisses it as a bonus action.
