The Elder Scrolls: Tamriel real

You blend into your surroundings, becoming nearly invisible. For the duration of the spell, you have advantage on Dexterity (Stealth) checks to hide, and creatures attempting to detect you have disadvantage on Perception checks to see you. You do not become fully invisible, but your appearance shifts to match the environment around you. The spell lasts for up to 1 hour and requires concentration.
