Blut

is an advanced Quincy technique which grants the user inhuman defensive and offensive capabilities.

Description
By making reishi flow directly into their blood vessels, users of this technique can drastically increase their attack and defense power. However, despite the significant danger this potentially presents to one's opponents, Blut possesses one major flaw; because the independent forms of the technique for attack and defense operate using two different reishi systems, they cannot be employed simultaneously.
