Retro Exchange adds transmutation stones that drop from aggressive mobs. 8 of these can be created to create a powerful Transmutation Stone. The stone can be used to transmute items, JEI is recommended to see all the recipes.
NoteThese textures were all done by Novamanga a while ago. I have just made a thread for them for future updates and pragmatism.
