Needle storm- using his magnetism Ikki can create hundreds of tiny needles from the iron sand in his gourd.
Shape manipulation - Ikki can control the iron sand-shape and determine how to used it as a weapon,shield, to float, grab and crush objects. Uses a large amount of chakra. Slow and close opponents should be wary
Magnetic repulse - Ikki can reflect metal objects back at the enemy kunai, swords ect. uses a reasonable amount of charka but with overuse can leave Ikki drained and vulnerable
Tetsu yōgan "Iron lava"
Ikki melts the iron sand and bends it with his magnetism causing major damage if it hits burning flesh and hardening over the body of the user it is aflicted on allowing Ikki to bend the user body where the sand has hardened on at will. A cruel jutsu indeed.
