"Doton could be considered the most sturdy and durable. Unlike the other elements, Doton permanently becomes apart of the environment, like how Kurotsuchi of Iwagukre's volcano erupted White Zetsu. All of that is true, unless it's destroyed by an outside force, of course. Then it can be used as a shield, trap, or a blockade against an opponent. An example of it being a trap, is when the Alliance trapped the Juubi inside, then filled it with cement. It can be used to block by erupting a small Doton wall to block Kunai, non-cutting winds, etc. It can withstand heat, and it's naturally superior to water. Due to the fact it can disperse a wave coming it's way. It's weakness is lightning however, shown with Deidara and Sasuke, Sasuke was able to render his attacks ineffective by charging lightning into his Clay Bombs (which is apart of the explosive release, that contains Doton). It can also be used in a liquid-like state, (i.e, mud) only adding to it's versatility. It can also provide a big advantage, since it can literally alter the battleground with it's structures, and traps. Based on my previous learnings from NK, I would firmly agree with him when I say it's the perfect mixture of supplementary, defense, and offense. Users would include, Ohnoki, Kazuzu, Kurotschi, Muu, Hiruzen and others" Carl says tiredly
