Cain's Ethereal Thread

You conjure a thin, nearly invisible thread of magical energy that can be manipulated with precision. The thread is strong enough to lift objects weighing a number of pounds equal to half the caster's intelligence score, and can be stretched up to 30 feet long. For the duration, you can use an action to control the movement of the thread mentally, allowing it to move or manipulate objects, tie knots, trace patterns, or perform many other intricate and delicate tasks within it's capability.
