Question: I’ve saw a thread somewhere the other day about how you can combine two enchantments on items using an anvil but i have no idea how it works, can anyone help?
Answer: You just need to put the enchants you want in an anvil to join them together. It can be done with book and book, item and book, or item and item. This can be to add different enchants together (if allowed) or to upgrade enchants. For example combine (books or items) an UNBREAKING II + UNBREAKING II = UNBREAKING III suggest reading the anvil and enchanting pages on Minecraft wiki. takes a while to learn but once you learn, you never forget.
