Tattoo Transformation

Your familiar can transform into a tattoo you carry on your flesh. When transformed into a tattoo, the familiar looks like a colorful and stylized version of itself and can't act except to turn back into a familiar. It isn't affected by area effects and must be targeted separately to affect it, which requires knowledge that it's a creature. This means you and your allies can heal or assist the familiar while most enemies stay unaware of its true nature.
