Dragon's Root

Dragon's Root (竜強さ根, Ryūtsuyosa Ne lit. Dragon's Power Root) is a rare herb that is capable of giving Dragon Slayers a rush of power, similar to when they eat their element.

Overview
Dragon's Root can only be found in a certain unnamed geothermal valley within Minstrel. This root is capable of giving users of Dragon Slayer Magic an immense surge of their magic, giving them a boost in power, similar to when a slayer consumes their element. To properly prepare this root it must be gathered then boiled. After it has been boiled it grows soft with a texture and taste similar to a potato.

Dragon Slayer's are only able to consume limited amounts of this root at one time or else they will grow incredibly ill, though for other magicians it seems that they can consume large quantities of Dragon's Root without any ill effect. For someone to acquire this root, they must either known an herbalist or a merchant who has their hands on a Dragon's Root at the moment or search Minstrel themselves, hunting for the root.

Those who choose to look for themselves often find themselves lost within the maze-like mountains in which Dragon's Root grows. Even if they were to find the root, there are horrific beats that must be slaid to make it out of the area alive.
