AnvilPlus

This mod allows you to combine 2 books in an anvil and get one book with one level more. Up to level 100!

Example: Prot4 + Prot4 = Prot5.

Also does mod Max Enchant X, but it also breaks villagers. Because of Max Enchant X villagers will sell books like Sharpness 9, Protection 35, ...

Mod AnvilPlus solves this issue! Now, with my mod villagers wont be broken, and you can combine your items with not broken villagers.

And because of mod Too Cheap, Anvils now no longer have annoying "Too Expensive!"
