Fruits of Darkness (or called Dark Fruits) are types of food that are meant to turn anything who eats it evil. They have four stages of eating it and are crafted by surrounding an Apple with Demoticum in a crafting table.
Every time something eats a Dark Fruit, it takes it to another png file showing a bite taken out of the fruit. If the Player eats it, they get nausea and momentarily lose control, behaving like a dragon however not becoming one. Normally, feeding it to an entity turns it darker or sometimes full-on demonic. If fed to an angelic mob, they get nausea and momentarily lose control as well but do not become eviler.
