Every environmental object in Dark Souls has an associated damage and health value, with breakable objects having a defense value of 0, 3, 90, 199, or 999 and unbreakable objects having an HP of -1. The player is only capable of destroying objects with defense values of either 0 or 3 such as boxes or tables while certain objects like the breakable wall at Sen’s Fortress, or the raised platform above the Asylum Demon at the beginning of the game, have higher defense values and can only be destroyed by enemies or hazards.
