I recently posted a topic asking if people consider using a alchemy and enchanting loop in order to create extremely powerful armor/weapons, enchantments and potions a cheat i.e. enchanting a "fortify alchemy" set of armor, creating fortify enchantment potions whilst wearing this armor, drinking the potions to create further fortify alchemy enchanted armor and then repeating these steps until caps are reached at which point you can create the best possible fortify smithing and fortify alchemy armor set.
However I've also recently read somewhere that a loop such as this is mentioned in game somewhere, specifically in books. I can't for the life of me find where I read this but I'm wondering has anyone else found anything in game that mentions the use of such a loop? I always thought it was just something that bethesda never intended to be used and overlooked after allowing it by mistake but I suppose if it is mentioned in game that would change things
