気, ki, energy (yellow):
Ki is a technique in itself. You can play a ki card from your hand in the action step, allowing a second charge and increasing your whole capacity. The only restriction for this technique is that you cannot do it with all the ki charged.
斬, zan, attack (red):
The standard attack technique. Its number can vary from 1 to 5, and represents both concentration's damage and ki cost. Launch an attack equal or greater than enemy's concentration means victory.
防, bō, block (green):
With this technique we will protect ourselves from attacks coming from the opponent. Like Zan, it has a value from 1 to 5 representing both its blocking strength and its ki cost. When played, it remains in the game until the opponent plays an attack of equal or greater value or we play another card, not counting ki.
雷剣, kaminariken, lightning blade (blue):
Costs 7 ki. This special technique is the ultimate attack. When played, the enemy's concentration is invariably reduced to 1. If the opponent had a block in play, eliminates it as well.
鏡剣, kagamiken, mirror blade (white):
Costs 9 ki. This special technique is the ultimate block. By playing it, we will be protected from any technique of our opponent, being the lightning sword the only one that can cancel it. Like all other blocks, it will remain only until we play another card, not counting ki.
呪詛, juso, curse (brown):
It costs 8 ki. When played, this special technique triggers an altered status in the enemy, wich can be:
Confused: Avoid recovering concentration if lost.
Weakened: -1 to all standard attack and block techniques.
Scared: You can't play attacking techniques if you don't have full concentration.
The curse card is placed next to the concentration cards, to indicate that this player is cursed. It can only be removed by playing a mirror sword.
死, shi, death (black):
It has no cost. This special technique summons death itself and brings the end of combat forward so that it is very close. When played, it forces fate mode, which will be explained later. It can only be countered by the mirror sword.
There's a special way of play a technique called "secret technique". Play a secret technique costs 10 ki no matter wich technique it is. We put the card in game upside down, and its effect doesn't get activated yet. A secret technique gets activated out of our turn as a response to an oponent's technique (ki technique doesn't count) or in our turn against a secret activated by the oponent. There's no limit in how many secrets you can have prepared.
You can use every technique even if you have not enough ki, at the expense of your own concentration. You lose two concentration cards for each missed ki card, so it's possible to suicide trying to do a too expensive technique.
