Awaken Idol

You touch the object used for the material component of the spell and imbue it with a non-sentient awareness. The target becomes a Wooden, Stone, Ice or Metal Idol, depending on the type of material used; if none of these apply, the statistics of one of these creatures still applies to it.
The idol 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.
