The Yoritomo are masters of the sea, and as a result of centuries spent fighting from ship to ship and on the beaches, their fighting style is highly unusual. The pitching and rolling of the waves has been incorporated into their style, which uses more movement than many major Schools. Likewise the Yoritomo have learned that protracted fighting is almost always detrimental to naval combat, and they have learned to ruthlessly exploit any weakness in their opponents' defenses. Finally, the corrosive effect of sea air on steel is well known, and as a result the Mantis have centuries of experience fighting with highly unconventional weaponry, in particular the kind of weapon most often relegated to peasants.
The Yoritomo Techniques essentially focus on dabbling in a little bit of everything. They have potent attacks, unhindered movement, and can cripple an opponent's Armor TN, among other things. The Yoritomo are jacks of all trades, but master of none, making them highly adaptable assets in a skirmish.
Rank One: The Way of the Mantis
Mantis bushi learn to fight on the pitching decks of ships and to use anything within reach as a weapon. You suffer no penalties to movement or attacks for rough or uneven terrain. You do not lose Glory or Honor when using improvised weapons, or weapons with the Peasant keyword, in combat. You suffer no penalties for fighting with a Small or Medium weapon in your off-hand if that weapon has the Peasant keyword. finally, you gain a bonus of +1k0 to all attack rolls.
Rank Two: Voice of the Storm
Your wild, unfettered attacks disorient your opponent and opens holes in his defenses. Every time you hit an opponent in melee, his Armor TN is reduced by 5. This penalty only applies to your attacks, and lasts for 2 Rounds. This Technique is cumulative (a number of times equal to your School Rank), and the duration resets with each application.
Rank Three: Strike of the Mantis
A Yoritomo strikes as swiftly as the storm. You may make attacks as a Simple Action instead of a Complex Action while using weapons with the Samurai or Peasant keyword.
Rank Four: The Rolling Wave
The Yoritomo Bushi reacts with the flow of combat, deftly dodging blows while reaching his target. If you move at least 5 feet, you gain a bonus of +10 to your Armor TN until your next Turn. You may sacrifice this bonus during your Turn before you roll any attack to gain two Free Raises that may only be used to perform the Knockdown Maneuver.
Rank Five: Hand of Osano-Wo
The Yoritomo Bushi strikes with brutal force, digging his weapons deep into his target. You may choose to activate this Technique by spending a Void Point as a Free Action. You keep an additional number of damage dice equal to your Strength. If these attacks hit a Prone target, you gain a bonus of +0k2 to the total of your damage rolls against that target.
