Evolving Weapon - When a shinobi from the the clan becomes a genin, they go through training (as if it was D ranked jutsu) to form their evolving weapon. This weapon must be something they can use at that rank, and will evolve into stronger versions of it's self as the shinobi gains skill (aka rank). Examples of this include a genin's wakazashi becoming a katana at chuunin, then become even longer as they progress to Jounin. The weapon doesn't have to change types, but will still evolve it's appearance. The weapon has no special properties or powers, other than being energy rather than metal and possibly things that can be achieve by building the weapon a particular way. It can even be broken, although it's just formed again after a few minutes. If the weapons are rather small (such as kunai or something considered equally small) this can be two of them. Fist can be choosen, and they will be covered in chakra that intensifies. They may even be covered in gaunlet or gloves or energy.
Those with bows produce energy arrows of normal arrow strength, or can use physical arrows that get a slight power boost. Any projectile, ammo or thrown, disappear after the attack. Staves, wands, gloves and chakrams enhance ijutsu or nin, depending on class. Bows enhance Ijutsu when used by a cleric as well, and don't have to be brought out to do so. Wizard staves and wands can also fire a projectile equal to a jutsu two ranks lower than them. They can only hold techniques that of the class' primary style. They only get to choose one (or a set) and this choice can't be changed once made. They tend to name them, updating the title as it grows in power. Starkin usually make their own personal jutsu that uses or affects the weapon. Five ot these jutsu don't count towards the total amount of jutsus know. They still must learn these normally, however. There must be as least one C and B rank amoung these, and only one can be S ranked.
