The Hall Obsidian

The Hall Obsidian is a location in Borderlands 3. It's a huge Eridian structure floating in space with its own life support and climate control systems. This is where Trial of Discipline takes place.

The Hall Obsidian is divided into four areas, where access to the next area is granted only once all of the enemies in the current area have been defeated. Once accesss to the next area has been granted, it is possible to revisit the previous area and loot ammunition boxes or any other loot they wish. Limited number of ammunition crates can be found in all four areas.

The last area is accessed via a sheer drop preventing Vault Hunters to go back. Only after the Proving Grounds boss has been defeated, Vault Hunters are given the opportunity to use exit-only Fast Travel Station.

While taking the trial, Vault Hunters should be aware of their position as the proving grounds have no natural obstacles preventing Vault Hunters to fall or be knocked over the edge.

If they choose to do so, Vault Hunters can use Drop Pod to teleport back and collect any valuable loot left behind.
