Polybook

Polybook is Polymer mod that adds server-side item called Polydex. It was made to make usage of Polydex feel more vanilla!

Polymer is a library to create server-side content that doesn't require any client-side mods installed! This means that you can join even from vanilla client!

You can still use /polydex command, but you can also just use the item. Polydex book uses vanilla texture, which means that your texture packs will still work!

Right-click with polydex to open Polydex menu, instead of using command

Recipe is simple: one block of any leaves and one book
