Nagabi Hiden: Rebirth of the Phoenix

This is an extremely powerful technique, and is considered to be a hiden of the Yakeru Clan. What it allows them to do is summon/create a phoenix, by combining all of the "fires" known to them, such as attitude, drive, and the types of fires they use. When combined it creates a large phoenix, that contains all of the usual properties of a phoenix, including it's ability to heal others. Its presence on the battlefield is said to be powerful enough to literally burn out the chakra off opponents. However, it also drains the chakra of the user at a high rate, meaning if it is used for longer than 10 minutes, the user will burn out as well.
