I have found this build to be rlly high damage but it’s all about constant movement, you stop for a few seconds and u die.
I usually start in air, use 4 then 5, switch to fire use 3 then 4 then 2 then 5.
by that time i need healing so i switch to ice and that gives me regen, then moving to earth, if i still need more heal i can pop mist and heal so i can’t be hit.
anyways let me know if u have any advice
