Crook

A Crook is an item introduced by the Ex Nihilo mod with the primary purpose of increasing sapling yield when used on Leaves. It can also be used on Infested Leaves for String and Silkworms, animals for void damage prevention (right-clicking on a passive mob pulls it towards the player), and monsters as a means of knockback. It is crafted with four Sticks in an inverted 'L' configuration.
