Once per combat, you can make X+1 melee attacks where X is the number of Samurai templates you possess. Each attack must be against a different target. You can move up to 10ft between each attack.
While unarmored, you get +1 Defense per level, up to a maximum of +6
Once per day, you can unleash a fierce intimidating shout, causing all creatures within a 10ft radius and 1HD or less to make a Save vs Fear or take a morale check, flee from you, or surrender.
If you are surprised, you have a 50% chance to act on the surprise round anyway.
Once per combat, you can make an impossible unerring strike with your katana. Your attack automatically hits. Roll for damage normally. If your target isn't adjacent to you, you can teleport next to them to make the attack (reality-bending acrobatics, bursting from a cloud of cherry blossoms, etc). Or you can make the your melee attack from ranged (a cutting gust of wind, a whirling blade, etc).
