Test Pit 1 is a location in Xenoblade Chronicles. It is located on the ground floor of the Ether Mine, and is found by entering the mine from the Drainage Control Room, then heading left at the first fork in the tunnels.
A lone M42 Scout Unit patrols the area. North of Test Pit 1 is an Earth Ether Crystal deposit containing Muscle Up II and Bleed Defence II crystals. The rank of these crystals increases during Colony 6 Reconstruction when Colony 6's Nature level is increased to level 3 and above.
