At-will, swift action, concentration, DC 13+; you step into an area of shadow or dim light and meld with it. While in shadow and remaining still, you are invisible. You can see and hear normally. If you move, you become visible as a shadowy silhouette (heavily obscured, advantage on Stealth). If you leave the area of shadow entirely (entering bright light), the spell ends.
