Arachnimotive

When this contraption made of a coil of eight metal tendrils tipped with a sticky membrane is attached to a belt, you can use a bonus action to release mechanical spider legs, increasing your height by three feet. Your speed does not change, and the legs can move up, down, and across vertical surfaces and upside down along ceilings, while leaving your hands free. You have a climbing speed equal to half of your walking speed. However, the legs don't allow you to move this way on a slippery surface, such as one covered by ice or oil.
