Avatar State

At level 17 you have mastered all 4 elements. As an action you can enter the Avatar State, which lasts for 1 minute. While in the avatar state you can use any of the techniques outlined in this class. You get a special reaction on every creature's turn. You can use this special reaction only on one of the 4 techniques in Disciple of the Elements (A Leaf on the Wind, Bursting Flames, Earthen Bulwark, and Receding Wave). Additionally, each of the 4 techniques in Elemental Attunement (Fangs of the fire snake, Fist of unbroken air, Grip of the mountain, and Water Whip) only cost 1 ki point to use while in this state. When this state ends you can reselect each of the techniques you have acquired in this subclass. Once you use this ability you cannot do so again until you complete a long rest.
