Arcanotech Siege Titan

Arcane Pilot. The Arcanotech Siege Titan cannot operate on its own. A Sorcerer must be attuned to the Titan and serve as its pilot. While attuned, the Sorcerer can use their spells through the Siege Titan’s weapons. The siege titan requires 1 hour of attunement.

Arcane Overload. The Siege Titan can amplify the pilot's spell energy into a devastating burst. When the Sorcerer casts a spell of 1st-level or higher, they can choose to overcharge it. This increases the spell’s level by one for the purpose of damage or effects (without consuming a higher-level spell slot). After using this ability, the Siege Titan takes 10 (3d6) force damage as its internal circuits momentarily fluctuate with the energy.

Multiattack. The Siege Titan makes two Arm Cannon attacks.

Arm Cannon. Ranged Weapon Attack: +9 to hit, range 100/300 ft., one target. Hit: 27 (5d10) force damage. If the pilot cast a spell before using this attack, it can deal an additional 1d8 force damage per level of the spell.

Shockwave Slam. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 25 (4d8 + 6) bludgeoning damage. Target must succeed on a DC 18 Strength saving throw or be knocked prone. If knocked prone, they are additionally stunned until the end of their next turn.

Pulse Shield (Recharge 5-6). The Siege Titan generates a magical barrier around itself. Until the start of its next turn, it gains temporary hit points equal to its Constitution modifier (5), and any creatures attacking it within melee range take 12 (3d6) force damage.

Empower Systems. As a bonus action, the Sorcerer pilot can funnel some magical energy into the Siege Titan’s systems. For 1 minute, the Titan gains advantage on all Strength checks and Strength saving throws, as well as an additional 10 feet of movement. This ability recharges after a short or long rest.

The Arcanotech Siege Titan can take 1 legendary actions. Only one legendary action option can be used at a time and only at the end of another creature’s turn. The Arcanotech Siege Titan regains spent its legendary action at the start of its turn.

Arcane Detection. The Siege Titan scans the battlefield for hidden threats. The pilot makes an Intelligence (Arcana) check to detect invisible or magically hidden creatures within 120 feet.
