I have looked around and couldn't find anything like my idea, please leave a link to something you think is close to what I say if it has already been suggested. In the show before Aang takes away firelord Ozu's (Sorry if spelled wrong) bending, he does this sphere type move that uses all 4 elements and is super faster in flying, stronger in bending. This could be another ability completely for the avatar, or it could be another part of the already existing move, avatarstate. I have no clue what the name would be, if it were to be treated as a separate move. I have an idea of how it could be done:
A torrent type of spinning around inside an airshield with fire and earth spinning around the player outside of the shield. Basically, diagonal torrent, airshield, diagonal spinning fire, vertically spinning earth. This requires the player to be like 2-3 blocks off the ground. While in the sphere, the player automatically has fireblast, earthblast, airblast, and watermanipulation bound to 4 slots (it will say in chat which ones), all of the moves require no source, they will come from the sphere. The way the move itself works is it is a toggle ability. The way it could work if it was a part of the move avatarstate is basically the same, but when you activate avatarstate, it is bound to a different slot automatically then it can be toggled at will on and off while the player is in the avatarstate. everything else mentioned would be the same. If on the poll you think the move should be another move entirely, suggest a name for it. If you voted for it to be a part of avatarstate, don't worry about suggesting a name, but you can if you still wish to.
Thank you for reading this quite long suggestion.
