Awaken Construct

After spending the casting time tracing magical pathways within a precious gemstone, 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. The target also gains the ability to understand one language you know. It also gains the ability to speak this language, provided that it has a mouth, speaker, or similar method of vocalising words.

Provided it is not immune to the condition, the awakened creature 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. If the creature cannot be charmed then it must be befriended in a similar way to other NPCs.
