Body Alterations -offensive
Blade:
Not a common ability, though a most useful one, is the ability to transform one's arm into a blade. Some manifest it as a long single-arm blade, others as a single double blade and others as two short blades. Regardless of form, they are extremely sharp, if a bit heavy compared to the claws. Users of the blade power depend on good footwork and great uppper-body strength. Instead of using multiple weak attacks they prefer single devastating blows that can shatter most defenses. Blade masters are known to be able to take down a single opponent in seconds, even though, due to the nature of the weapon, they are somewhat less adept in taking down multiple opponents. There is a long-standing competition between claw and blade users. Possession of either of these two powers is necessary to be considered a full fledged adult and both are required to progress past the lowest level in the Warrior's branch.
Claws:
Commonly the first ability to be unlocked, the appearence differs from user to user. However all users are adept in its use, since it is a very easy ability to learn. Attacks with the claws power utilize acrobatics, twists, pivots and short dashes in order to attack or defend. Masters of this power are known to wipe out squads of enemies fast but are more capable against many weak opponents than a single strong one. Note that while the appearence of the claws power is different to each user, it still is always obvious, usually consisting of 30 to 40 cm long claws. To not possess this power is considered a sign of weakness by some clan members, regardless of how skilled one is.
Mutations: Claw mutations include the ability to use them at a long range by throwing them. This is either done by making a swiping motion whereupon they are released or more complicated by having a separate compartment that closes up and fills with blood. Upon reaching a certain pressure it is launched like a pistol shot. Both ways need time to learn and master. They are most commonly used in either silent assassinations or in case there is no time to switch to jutsus or a more suitable attack.
Hammer:
One of the not-so common abilities is the hammer. It usually shifts the hands into huge spheres of bone, enabling some very destructive attacks. Rarely used due to its lack of speed, it is a brute's weapon. Requiring extreme upper-body strength, it eats up one's speed. There are very few masters of the hammer power, but the ones that were, were known for extreme strength and stamina, able to create immense shockwaves, thus hurting the enemy even if they missed.
Mutations: Spikes or the extremely rare ability to combine it with the whip power giving it a chain of sorts. One user was even known to be able to cut it off in order to launch it like a cannon-ball on his enemies. He was revered as a most destructive shinobi, his down-time however proved to be a huge problem in missions that had small fights in short succession.
Whip:
Also a common power, the whip usually consists of a long retractable muscle with supporting bones, much like a snake's anatomy, with a sharp bone 'head'. Whether it is in the shape of a harpoon or a blade is often irrelevant. It is most often used to attack enemies outside of normal range, but it is also very useful in scaling surfaces or swinging through places. Experts of the whip are known to be able to line up enemies and attack them at once or even catch an enemy or objective. A caught enemy can even be constricted like a boa. Masters have been told to make their whip rebounce of surfaces to hit an enemy or even change its direction mid-flight with precise motions.
Mutations: Whip mutations include the extremely rare ability to substitute the head for one's hand or claw. The rarest however is the ability to create a third eye of sorts on the head of the whip. In a hundred years only two have been known to possess this ability, making it one of the rarest in the clan. The most common mutation, for mutations that is, is the ability to sprout bone blades from the sides of the whip, enabling it to attack enemies with lethal force even if they are not the target of the head itself.
