About[]
The environment around the Wine Glass consists of a rocky mountain, with a long, massive and deep underground lake shaped like a wine glass. Deep inside this lake, lays a FUG secret base used by Yu Han Sung to hide Twenty-Fifth Baam in order to make him a new Slayer Candidate under the alias "Jyu Viole Grace".[1] Somewhere inside this base, there is a location used to contain a "mysterious power" with bright "red light" that later was entered or inserted into Baam's body.[2]
The Shinsu density or concentration in the Water inside the lake can increase a person's Shinsu Control and boost or enhance their skill to manipulate shinsu. Baam felt his shinsu control was enhanced greatly when he travelled with Rachel inside a Shinsu Bubble made by Hansung.[3][4]This sudden increase of power allowed Baam to freeze or stop the movement of the Bull Shinheuh with the Fast Skip technique, just for a couple of seconds.[5] In the Tower of God (anime), this "power boost" was shown when Baam's hand shine bright gold color on the Episode 11.
