By combining Lava Release with Water Release, the user is able to create a pyroclastic mudflow that is capable of destroying almost anything in its path. Using this technique while on top of a hill or mountainside increases its speed and effectiveness. Because of this technique's speed, the obsidian debris inside the mud and the heat of the mudflow, it is considered the Kazan clan's most powerful technique. The strength of this technique is great enough to cause a shinobi reincarnated by the Impure World Reincarnation technique to need a significant amount of time to regenerate.
