For the duration of the spell, you can use your action to see through your Kruthik's eye and hear what it hears, and continue to do so until you use your action to return to your normal senses. While perceiving through the Kruthik's senses, you gain a Tremorsense with a range of 60ft. and can speak Kruthik, though at the start of each turn you must succeed on a Wisdom saving throw against a DC equal to 8 + your Proficiency Bonus + your Wisdom Modifier or be forced to attack the nearest creature using Primal Savagery.

Also, while you are perceiving through the Kruthik's senses, you can cast the Primal Savagery cantrip, which counts as a sorcerer spell for you and doesn't count against the amount of cantrips you know.

This cantrip also deals magical Piercing instead of Acid damage and whenever a damage die is higher than 6, you heal an amount equal to half of your Proficiency Bonus rounded down.
