1.) Ki Transform and ascend to Level five or higher
2.) Create a ki ball in one hand, it should feel heavy
3.) Instead of firing it go up to your opponent and strike them with the palm that holds the ki ball.
The Ki ball will burst on impact and hurt your opponent.
The higher you ascend the stronger the attack is.
The attack still effects people of the same ki level but only minimally injures those who have a ki level equal to or greater than your own.
If you shoot the psi and strike your opponent at the same time it does more damage.
