Not all walls are created equal; some are crumbly, broken walls that are ready to fall apart. There also exist the secret walls, functionally identical to broken walls but much subtler and often used to hide paths to secret rooms.
Whereas regular walls are often the basic pillars of dungeons and used only to separate rooms and room sections, crumbly walls will function like regular walls until they are destroyed.
- Crumbly walls function identically to regular walls
- Once destroyed, terrestrial and flying creatures can travel through the rubble unhindered, while seep movement is prevented
