Using this technique, the user is able to merge with another creature's body to strengthen his own a great deal. The technique uses the user's body as his own, as the seal draws the other subject into his body.

The user gains the subject's bonus to ability scores as an enhancement of his own (for
example, if the subject has a Strength score of 14, the user's own increases by 14.) If the chosen creature has any supernatural or extraordinary abilities, including Bloodlines and Templates, the user will benefit from them as well, but will not be able to manifest two bloodline powers at once. The user adds half the others Chakra Pool and health as well.

If the user fails a massive damage save or falls unconscious while the transformation is still in effect, the technique ends and both creature are once again separated. If the user dies, runs out of Chakra, suffers ability score damage, Chakra Coil damage or any specific type of long lasting effects when the transformation is still active, the subject will also share them.

Once the transformation ends, both the user and the subject will become Exhausted and reduced to 1/10th of their total hit points, lest the total was below that number, in which case it is reduced to 1 hit points.

This technique cannot be used with another fusioned creature, nor can it be used to fuse with another creature while a transformation is still in effect. The technique uses five seal slot on the user's body, which will be free once the transformation expires or is canceled.

Expendable Components: The user and the subject's blood, which will be mixed and used in the painting of the seals. Scribing the seals requires a Int check (DC 28) to be made, not necessarily by the user, and takes 30 minutes. If the check was failed, the sealing process will fail without the user noticing until the end.
