how bout this?
you hurt yourself with the extra specialty you get?
you try and attack an opponent and BAM! you get hit!!
example:
Lvl 1 suna shuriken:
You throw shuriken made of sand at the enemy but they turn around in mid air and fire back at you!
You get hit for ** damage!
you get hit for ** damage!
you get hit for ** damage!
and so on =)
defensive moves:
you create a shield of sand but it is so heavy that it becomes hard for you to move and defend yourself from the attackers!
Defense ** + -**.*
