The Arsenal is a cave located underneath Tatarasuna near the Mikage Furnace.


The Arsenal is located south of the Mikage Furnace in Tatarasuna. The gate to The Arsenal is located near the water on the east side of the cave.


To be able to access the area around The Arsenal, part of Tatara Tales must be completed so that the Mikage Furnace area can be unlocked; before then, the Containment Field will prevent players from entering. The Arsenal itself can be entered after obtaining 3 Keys to Some Place that are found around Tatarasuna in Common Chests. Upon first entering The Arsenal, three Ruin Sentinels will spawn.

Obtaining the diagram grants a Wonders of the World achievement, "Blade of Tatara". Additionally, there is 1 Electroculus, a number of Naku Weeds, and an Enigmatic Page.
