Pentadrone

The pentadrone can't be compelled to act in a manner contrary to its nature or its instructions.

If the pentadrone dies, its body disintegrates into dust, leaving behind its weapons and anything else it was carrying.

The pentadrone makes five arm attacks.

Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 5 (1d6 + 2) bludgeoning damage.

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.
