Traits

Cog's Sight. The cog can see through magical darkness.

Interconnected. The cog is techno-magically connected to all other cogs. The cogs can speak and otherwise send data to each other telepathically through the cogwork.

Magic Resistance. The cog has advantage on saving throws against spells and other magically effects.

Nullification Eye. The cog's central eye creates an area of antimagic, as in the Antimagic Field spell, in a 30-foot-cone. At the start of each of its turns, the cog decides which way the cone faces and whether the cone is active.

Prismatic Core. The cog is powered by a prismatic sliver. If the cog is reduced to 0 Hit points it disintegrates. Roll a d6. One a 1, the sliver explodes. Each creature and object within 5 feet of the cog takes 22 (4d10) Force damage. A target reduced to 0 Hit Points is disintegrated.

Actions

Multiattack. The cog makes two armblade or armrifle attacks.

Armblade. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 8 (1d10 + 3) Slashing damage plus 7 (2d6) Force damage.

Armrifle. Ranged Weapon Attack: +5 to hit, range 60/180 ft., one target. Hit: 14 (2d10 + 3) Force damage.

Bonus Actions

Targeting Laser. The cog targets a creature or object it can see within 120 feet of it with a precise beam of blue light. Creatures with cog's sight have advantage on ranged attack rolls against the target. The laser remains until the target is behind full cover, the cog switches targets, the cog deactivates its targeting laser, or if the cog dies. The cog cannot use this bonus action if it is Blinded.

Reactions

The cog can take up to two reactions per round, but only one on each turn.

Force Field. When the cog or another creature it can see within 30 feet of it takes damage, the cog can project a force field around it. Damage the creature takes is reduced by 14 (4d6). The cog cannot use this reaction if it is Blinded.

Description

Construct of Esper. The cog is loyal to Esper and the Cognition. To prevent reverse-engineering, appendages or other pieces of the cog disintegrate when removed from it.

MKI. The Mark 1 Cogs were slow but durable, built to without the unusual nature of the Astral Plane: both the Astral Sea and Wildspace. Known to sometimes explode after destruction.

Special language. The cog knows a dialect of Deep Speech. It can be described as synthetic in sound. Additionally, there exists a written script for this dialect of Deep Speech known as Wing-Dings.
