Many people complain that there should not be a level-limit to anvils. However, I have never encountered this issue IF I’m using it properly. I have made the perfect armor / tools with all the best enchants multiple times (on vanilla), and if you combine the books in the correct order, you never reach the limit.
Sorry for pinging so late but this is hilarious. Someone went through all the pain to find the ideal order of enchants. Chaotic good.
