The Toil of Spoiling Vis is the seventh Abandoned Auger Mine in Borderlands 4. These mines act as combat challenges scattered across the game’s later areas. Each mine contains unique enemy waves and culminates with a powerful boss.

Unlocking this mine requires reaching Dominion City and completing the main mission Shadow of the Mountain. From there, the activity icon appears on your map, though finding the actual entrance takes a bit of searching.

Facing Axemaul, the boss of The Toil of Spoiling Vis

At the end of the mine lies the boss battle with Axemaul, a tough boss characterized by a two-layer health system: a protective Armor bar followed by a Flesh health bar.

Given Axemaul's armored nature, players benefit most from weapons dealing Corrosive damage to strip armor and Incendiary damage to burn flesh, making these damage types ideal for quickly defeating him.
