Name: Irounaku no Taka no Hengen [Complete Falcon Transformation]
Rank: B
Type: Ninjutsu
Chakra Cost: 6500
Range: Only the user
Element: None
Description: This jutsu has three stages.
Stage 1: This is the stage at which one who had just learned the jutsu would be. Most child to teenage clan members are at this stage. At this stage, when the jutsu is used, the clan member slowly transforms into a gigantic falcon. An example of a fully transformed clan member can be found here. At this point, the clan member cannot control the transformation, and the whole body (excluding the face) transforms.
Stage 2: At this point the clan member can choose which parts of their body will transform, but only general areas, like arms, legs, head, etc. They can narrow it down to one arm or one leg, but could not narrow it down to a hand or a foot, and would have to transform the entire limb.
Stage 3: The clan member now has total control over the jutsu, and can even choose to only transform inner parts of the body, such as the vocal cords or ears. Nothing else will transform unless they want it to.
For all stages the transformation lasts as long as the clan member wills it to, or until they lose consciousness. This requires handseals to perform but not to undo, as forming handseals with talons would be impossible.
