Im guessing we're in short range, so when your clone creates the spike I use:
(Doton: Doryo Dango) - Earth Style: Ball of Graves
Rank: B
Type: Offense
Range: Short/Mid
Chakra Cost: 20
Damage Points: 40
Description: The user is able to overturn the earth into a large dumpling-shaped chunk of dirt the size of a mausoleum. Using immense strength, they can then lift up the ball and hurl it at his/her opponent, flattening everything in its path.
which flattens your clone and water spike, then I use:
Fuuton: Dai Kamaitachi (Wind Style: Great Cutting Whirlwind)
Type:Attack
Rank: B
Range:Short-Mid
Chakra Cost:20
Damage Points:40
Description: A bigger version of the cutting whirlwind.
then:
(Raiton: Gian Yari) - Lightning Style: False Darkness Spear
Rank: B
Type: Offense
Range: Short/Long
Chakra Cost: 20
Damage Points: 40
Description: The user emits a spear of lightning from their mouth. The spear can then split apart to strike multiple enemies.
combining with the cutting whirlwind, and splits apart while in the cutting whirlwind, making many spears of lightning and a cutting whirlwind
