Clockwork Soldier

Shared Network. As long as there is more than one clockwork soldier linked to the same master they can share visual, auditory, and telepathic information with each other.

Magic conduit. The master of a clockwork soldier is capable of taking fully control over a soldier choosing what actions the soldier takes. After taking possession of the soldier the master may use an action to cast a spell from their personal spell list, up to a 5th level spell. The spell's point of origin is considered to have come from the clockwork soldier's location rather than the castor's. The verbal, somatic, and material components can be provided from either the castor or soldier's body.

Immutable Form. The clockwork soldier is immune to any spell or effect that would alter its form.

Magic Resistance. The clockwork soldier has advantage on saving throws against spells and other magical effects.

Magic Weapons. The clockwork soldier's weapon attacks are magical.

Multiattack. The clockwork soldier makes two, arm blade or needle volley attacks. 

Arm Blade. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 14 (2d8 + 5) magical slashing damage.

Needle Volley. Ranged Weapon Attack: +9 to hit, range 20/40 ft., one target. Hit: 15 (4d4 + 5) magical piercing damage. On hit the target must make a DC 14 Constitution save or be paralyzed for 1d4 + 1 rounds.

Self Destruction Discharge (Recharge 5-6). The clockwork soldier stabs itself with its blade causing its power system to begin sparking. Releasing a large discharge of lightning in an area. Area Attack: Each creature within twenty feet must make a DC 17 Dexterity saving throw or take 5d8 + 15 lightning damage and be paralyzed for two rounds. On a successful save the creature takes half damage and is not paralyzed. The clockwork soldier's maximum HP is reduced by 50 and it gains vulnerability to all damage until the end of its next turn.

Attack of Opportunity. When a creature leaves the clockwork soldier's attack range, it may take an attack of opportunity.
