Ever though about dust bending(technicallu a form of earthbending)? But it requires a breathing technique and you cant bend other things when you dust bend. I guess a advantage would be air sensing i guess through all the dist in the air, but you cant use seismic sense at the same time
Thanks for the chapter :)
Slightly disappointed in the MC just showing himself, assassination would have been better, with 1 earth spike through the head, or aimed at an important part of the body. Quick, easy, swift and cant be traced.
