[Shadow Stranger]

A Bol file is used to list the monsters, items and props found in a dungeon.
For the three outdoor zones, a place may be covered by its own Bol file if it has a "building", tower, hut, dungeon entrance... Other than that, the place is covered by a Tol file.
Tol files are just like Bol files, except that the former have provision for recording the outdoor Bol areas.
