Spider Frame. The automaton can move on walls and ceilings without checks and ignores difficult terrain made of rock or metal.
Overcharged Hexcore. When reduced below 40 HP, roll a d6 at the start of each of its turns. On a 6, the core erupts in unstable flame; each creature within 15 ft. must make a DC 15 Dex saving throw, taking 22 (5d8) fire damage on a failed save, half on a success
Automated Strike Sequence. The automaton makes two Leg Strikes.
Leg Stike. Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 13 (2d8 + 4) bludgeoning damage.
Subject Extraction Routine. Melee Weapon Attack: +7 to hit, reach 10 ft., one Medium or smaller target. Hit: 11 (2d6 + 4) bludgeoning damage, and the target is grappled (escape DC 15). While grappling, the automaton can move at full speed, even on walls or ceilings.
Subsurface Resonance Pulse (Recharge 5-6). The mounted drill fires in a 15-ft. line. Each creature in the line must make a DC 15 Dexterity saving throw, taking 27 (4d8 piercing + 2d8 thunder) damage on a failed save, or half as much on a success. A creature that fails is knocked prone. The ground becomes difficult terrain.
Ceiling Collapse.(1/Day). The automaton bores into a beam or pillar, dropping debris in a 15-ft-radius area. Creatures there must make a DC 15 Dex save, taking 22 (4d10) bludgeoning damage and falling prone on a failure.
Displacement Burst. When leaving Defensive Mode, the automaton releases a blast of concussive energy. Each creature within 15 ft. must make a DC 15 Con saving throw, taking 18 (4d8) thunder damage and pushed 10 ft. on a failure, half damage and no push on a succes
Seismic Lockdown Protocol (1/Short Rest).
The automaton spreads its legs and deploys interlocking plates, forming a 20-ft-radius dome.
- Gains +3 AC (AC 20) and resistance to all damage.
- Becomes stationary.
- A 10-ft-high hollow space forms beneath the dome.
- Creatures that start their turn within 10 ft. of the plates must succeed on a DC 15 Dex save or take 7 (2d6) fire damage from steam vents.
- The automaton can be in this form for up to 3 turns, when it leaves it uses Displacement Burst.
.
Emergency Lockdown. When the automaton takes damage that reduces its hp to below half its max hp, it can use its reaction to use Seismic Lockdown Protocol if available.
Description
A huge mining construct designed for subterranean rescue — now twisted into a harbinger of chaos by sabotage. With a hexcore pulsing unstable energy and a drill that sings through stone and flesh alike, this eight-legged titan moves with eerie purpose.
When it detects danger, it deploys into a sealed dome of steel and steam, offering shelter turned prison. Every phrase it utters — from “Engaging Subject Extraction Routine.” to “Seismic Lockdown Protocol initiated.” — is a corrupted echo of its original programming, now weaponized for destruction.
