Mods/The Aether/Zephyr

Zephyrs are large, cube like mobs that hurl snowballs at you. When hit by such a snowball you are pushed a significant distance away. Being on the edge of islands or drops is therefore very dangerous when Zephyrs are near because their attacks knock the player backwards, which can cause them to fall off islands/cliffs. Zephyrs are usually considered aggressive mobs but do nonetheless appear on peaceful because they do not inflict direct damage. Zephyrs attacks are also similar to that of a ghast's. Upon defeat, they drop a stack of cold aerclouds.
