Powers

Molds of the Ruby are said to allow the forging of bronze alloys. Therefore, the powers granted by this Eureka are related to metals, that can be protruded from the user's body. When used, the body and clothes of the user gains a metallic aspect and several dark tattoos drawn on it.

This particular substance is able to render the targets unable to move. However, it takes a significant amount of time before the said allergen to activate.
