Great Tree Arc

Great Tree Arc (大樹のアーク Taiju No Āku) is a Lost Magic.

Description
A type of Lost Magic which allows the user to manipulate trees at their own will and produce trees for various purposes, mainly for battles. The user can also create explosions by condensing the power of the earth into the fruit of the created trees, giving the user advantage in battles. Furthermore, it allows the user to merge themselves with trees and hide inside it. It also gives the user the ability to harness all of the power stored within the earth itself. The Magic also allows the user to drain the power of a land which apparently drains all the power of the people connected to that land.

Side Effects
Overusing this form of Lost Magic gives a side-effect that causes the user's body to transform into a big tree.
