Attacks using these tools mostly revolve around either throwing them at the ground near an opponent or having them partially buried to cause the surrounding earth to move. Large versions of these spheres are placed throughout the Inagara grounds to serve as a defensive tactic."@en . "Inagara Chakra Spheres"@en .

When he realized they could absorb chakra, he began adding his fire nature chakra. He can throw the spheres directly at an opponent to sear their flesh, slam them into the ground to have flames burst out, or leave them partially buried in the ground to ignite at a later time."@en .
