Crystalline Intelligence

Artificial Intelligence. The golem possesses its own personality, memories, and intelligence. It can communicate verbally and act independently. It is friendly toward its creator and their allies.

Constructed Nature. The golem doesn't require air, food, drink, or sleep, and it is immune to disease.

Crystalline Body. The golem has advantage on saving throws against effects that would knock it prone.

Shared Initiative. The golem shares its creator's initiative count and takes its turn immediately after them. It can move and use its reaction independently. Unless commanded, it takes the Dodge action.

Arcane Conduit. While the golem is within 30 feet of its creator, the creator has advantage on Intelligence checks. Additionally, when the creator casts an artificer spell with a range other than Self, the creator can choose to have the spell originate from the golem's space instead. The creator must be able to see the golem and remains responsible for all other spellcasting requirements, including concentration.

Crystal Slam. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 10 (1d8 + 6) force damage.

Crystal Guard. When a creature the golem can see hits a target other than the golem within 5 feet of it with an attack, the golem can impose disadvantage on the attack roll, potentially causing it to miss.
