Arcane Intelligence

After spending the casting formulating the arcane pathways of the artificial mind inside the cog, you touch a Huge or smaller construct. The target must have either no Intelligence score or an Intelligence of 3 or less. The target gains an Intelligence of 10, and the ability to speak one language you know.

The awakened construct is charmed by you for 30 days or until you or your companions do anything harmful to it. When the charmed condition ends, the awakened creature chooses whether to remain friendly to you, based on how you treated it while it was charmed.
