Tekki Kata or Iron Horse Kata
By Kuseru

Also called Naihanchi Kata. A gathering of all the body's physical and psychic forces in one spot, to be channeled into one use. Tekki can be used to add to Maintain Balance rolls. Using a Iron Horse Kata limits the character to only offensive (attacks) or defensive actions per melee round.
Tekki can be used to enhance every Maintain Balance roll in that melee. The ability doubles the Maintan Balance rolls for that melee. All remaining attacks or defenses are normal without benefit of any bonuses of any kind. If Tekki is used for attacking, then the character can do absolutely no defensive moves for the remainder of the round (only a roll with punch/fall or impact is possible).
Defending by using the Tekki works much the same way, if used for defense, the character can do no attacks/strikes and can only make defensive moves like parries, dodges and rolls (all have the character's normal bonuses).
Using Tekki does not cost Chi points, but characters whose Chi has reached zero, or who have negative Chi, are unable to use Tekki.
