Stolen Shape

The blood remembers where it came from.
• Increase your Charisma score by 1, to a maximum of 20.
• If you have successfully used Feed on a humanoid creature and are still satisfied from that use of Feed, you can magically imitate that creature’s physical form when you transform with Walk Unhindered, instead of simply transforming your lower body into humanoid legs. A creature can attempt an Intelligence (Investigation) check contested by your Charisma (Deception) to see through your disguise. You can use this feat whenever you Feed, but you immediately transform back into your lamia form when you are no longer satisfied.
