Zoufukushoku Haki

Zōfukushoku Haki is a Haki technique developed by Poe A. Edgar to allow him to use his own great reserves of willpower to increase the effectiveness of the soldiers around him.

Overview
Zōfukushoku Haki as a form of Haki requires extremely advanced attunement to both basic shades of Haki to complete both steps of the process. The first step requires Kenbunshoku to harmonize the user's Haki, while the second requires Busoshoku to both provide substance and transfer the user's haki to its target.

Step one requires the user to sense the wavelength of their intended recipient's haki and shift their own to match it. Without haki on the same wavelength, it becomes impossible for the recipient to make effective use of the supplied haki. So the closer the match the better. A master of this technique will be able to do an exact match, and the user will feel no difference between their Haki and the supplied amount.

Step two requires the user to pool their Haki outside of their body, and once they extract the desired amount they must then flow it into the recipient's body.

When done properly, the recipient's haki will be boosted, increasing their own power and abilities potentially far above what they would normally be capable of.
