First off i really love that mod, its really fun to play.
But from what i saw i think the waterbending is to an extend a little underpowered.
idk if you still plan of adding stuff to this mod but, i would love to have some buffs to water bending.
A few suggestions could be
-A better defensive abilities like an ice wall like its used in the show.
-A movement abilitie to use outside of a body of water(With a canteen in the inventory)
I hope you read this and consider my options
