Shell of Darkness

This spell creates an immobile variable between 5' and 30' radius shell of darkness with the caster at its centre. The shell counts as a magic item, and is automatically attuned to the caster. No light can pass through the shell either way, It is utterly black. +7 levels the shell moves with the caster at the centre. At +14, you can resize the radius as a 5' move action. This effect is particularly used to mask light sources while resting, or moving at night or in darkness where your light is visible from a long distance away.
