Yggdrasil Abyss

Yggdrasil Abyss (lit. "Dark World Tree") is a Noble Art of Ein Abgrund.

Description
Yggdrasil Abyss is a Noble Art, that is activated once the user's mana is consumed entirely by their Device and the user's body turns into a 50-meter tall tree. In this form the user is able to divert their magic into the surrounding soil, corrupting the vegetation around them and turning ordinary plants into magical plants. The magical plants created are more powerful while the user is in this form, which their attacks can even break through Yui Tatara's Total Reflect and even hundreds of beasts composed of plants can be summoned at the same time. The branches and the roots of the tree itself can also be used for attacking the opponent.
