Arrowshaft Cavern is a large, multi-level cavern in the eastern Nibenay Basin just south of Collapsed Mine. There are a lot of chests within the cave.
- Arrowshaft Cavern
- Lower Arrowshaft Cavern
- Arrowshaft Cavern Subterrain
There are plenty of chests, as well as a generic selection of level-dependent creatures guarding them. There is a 10% chance that an Orcish Adventurer will spawn inside Arrowshaft Cavern.
The final chest found at the end of cavern contains random leveled items and additional valuable treasure, and is guarded by a "boss" monster (at higher levels, in most cases a Minotaur Lord).
