This is a one command creation which allows you to have a few different abilities. If you are falling, a strength effect is applied to you. The more you fall, the greater the strength effect. Spider eyes give you speed but also hunger. Dropping a dye on the ground acts as a smoke bomb that starts 3 seconds after you throw it.
