• You learn to speak all of it’s languages. When the creature wakes up, it cannot speak for the duration of the feature.
• If it’s a spell caster, you can learn one spell from it’s spell list, the spell cannot be of a higher level than you can already cast. You may cast it once, without using a spell slot.
• If it has an intelligence of 12 or higher, you may steal 2 from its score and add them to your own, with no maximum. The victim regains its intelligence at the end of the duration.
