Necrodermal Virus

The Necrodermal Virus is an item added by Botania. When used on a tamed Horse (including donkeys and mules), it will turn it into a zombie horse, doubling its health and speed, increasing jump height by 50%, and nullifying all fall damage taken by the horse. The transformed horse will drop the horse armor it wears; mules and donkeys will drop their attached chests and their contents.
