Axiomatic Mind. The pentadrone can't be compelled to act in a manner contrary to its nature or its instructions.
Dismantlable. If the replica pentadrone dies, its body falls into a pile of parts (gears, plates, screws, and wires), leaving behind its weapons and anything else it was carrying.
Multiattack. The pentadrone makes five arm attacks.
Arm. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit:5 (1d6 + 2) bludgeoning damage.
Paralysis Gas (Recharge 5–6). The pentadrone exhales a 30-foot cone of gas. Each creature in that area must succeed on a DC 11 Constitution saving throw or be paralyzed for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
