This addon adds the four nations bending abilities from the show Avatar the last Airbender, without needing experimental gameplay enabled, so it works on servers, realms, and already modded worlds with virtually no lag. Create realms, and customize the addon to fit your playstyle using the in-game settings.

When you start out, nothing will happen. First, run the command !scroll. After that, you can choose your bending by opening it (long press or right click). The options are avatar, fire, earth, water, air, and human (normal vanilla Minecraft, with the ability to learn chi-blocking).

Nothing will happen when you pick a bending style - you need to choose your moves for each of your “slots”. For instance, if you sneak and then punch you will use whatever move is bound to slot 4. Let’s say you are an Airbender and used the scroll to set slot 4 to Air Blast - when you sneak and punch, you will use Air Blast. You can use your scroll to bind moves to slots. Just right-click on your scroll, and click on the sub-menu button “Choose Slots”. Try picking slot 4 first, since it’s the simplest. Eventually, you’ll have your slots memorized, and a set of 6 moves you like best. These 6 that you have “slot-loaded” is what makes you different from other benders of the same type.

Each type of bender will have a different move set, and each individual bender will have an even more varied set of moves. As you level up, you get access to more moves. To level up, simply go about as normal - using moves will help you level up, but don’t try to afk, it won’t work.
