Locks, Bars, and Seals: Dungeon doors may be locked, trapped, reinforced, barred, magically sealed, or sometimes just stuck. All but the weakest characters can eventually knock down a door with a heavy tool such as a sledgehammer, and a number of spells and magic items give characters an easy way around a locked door.
Attempts to literally chop a door down with a slashing or bludgeoning weapon use the hardness and hit points given in Table: Doors. Often the easiest way to overcome a recalcitrant door is not by demolishing it but by breaking its lock, bar, or hinges. 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 an average person might be able to break with one try.
DC 16–20: a door that almost anyone could break, given time.
DC 21–25: a door that only a strong or very strong person has a hope of breaking, probably not on the first try.
DC 26 or Higher: a door that only an exceptionally strong person has a hope of breaking.
For specific examples in applying these guidelines, see Table: Random Door Types.
Locks: Dungeon doors are often locked, and thus the Open Lock skill comes in very handy. Locks are usually built into the door, either on the edge opposite the hinges or right in the middle of the door. Builtin locks either control an iron bar that juts out of the door and into the wall of its frame, or else a sliding iron bar or heavy wooden bar that rests behind the entire door. By contrast, padlocks are not built-in but usually run through two rings, one on the door and the other on the wall. More complex locks, such as combination locks and puzzle locks, are usually built into the door itself. Because such keyless locks are larger and more complex, they are typically only found in sturdy doors (strong wooden, stone, or iron doors).
The Open Lock DC to pick a lock often falls into the range of 20 to 30, although locks with lower or higher DCs can exist. A door can have more than one lock, each of which must be unlocked separately. Locks are often trapped, usually with poison needles that extend out to prick a rogue’s finger.
Breaking a lock is sometimes quicker than breaking the whole door. If a PC wants to whack at a lock with a weapon, treat the typical lock as having hardness 15 and 30 hit points. A lock can only be broken if it can be attacked separately from the door, which means that a built-in lock is immune to this sort of treatment. In an occupied dungeon, every locked door should have a key somewhere.
A special door (see below for examples) might have a lock with no key, instead requiring that the right combination of nearby levers must be manipulated or the right symbols must be pressed on a keypad in the correct sequence to open the door.
Stuck Doors: Dungeons are often damp, and sometimes doors get stuck, particularly wooden doors. Assume that about 10% of wooden doors and 5% of nonwooden doors are stuck. These numbers can be doubled (to 20% and 10%, respectively) for long-abandoned or neglected dungeons.
Barred Doors: When characters try to bash down a barred door, it’s the quality of the bar that matters, not the material the door is made of. It takes a DC 25 Strength check to break through a door with a wooden bar, and a DC 30 Strength check if the bar is made of iron. Characters can attack the door and destroy it instead, leaving the bar hanging in the now-open doorway.
Magic Seals: In addition to magic traps spells such as arcane lock can discourage passage through a door. A door with an arcane lock spell on it is considered locked even if it doesn’t have a physical lock. It takes a knock spell, a dispel magic spell, or a successful Strength check to get through such a door.
