Breaking Doors
Structure doors might be locked, trapped, reinforced, barred, artificially sealed, or sometimes just stuck. All but the weakest characters can eventually break through a door with a large weapon such as an assault hammer or other heavy tool.
Attempts to chop down a door with a slashing or bludgeoning weapon use the hardness and Hit Points given in Table 11–10: Doors. When assigning a DC to an attempt to knock a door down, use the following as guidelines.
- DC 10 or Lower: A door just about anyone can break open.
- DC 11–15: A door that a strong person could break with one try and that would take an average person one or two tries.
- DC 16–20: A door that almost anyone could break, given enough time.
- DC 21–25: A door that only a very strong person has any hope of breaking, and probably not on the first try.
- DC 26 or Higher: A door that only an exceptionally strong person has any hope of breaking.
