View source for Door

{{features}}
'''Doors''' are ways of moving in and out of rooms. They are distinct from [[trap door]]s and [[drawbridge]]s. Open doors in vertical walls are represented by {{brown|-}}; open doors in horizontal walls are represented by {{brown|{{!}}}}; and closed doors are represented by {{brown|+}}. A doorway without a door is represented by {{white|.}}.

A doorway may have no door, a broken door, an open door, or a closed door. A closed door may be locked or unlocked. A closed door may be untrapped or trapped.

A closed door may be secret, in which case it looks like a [[wall]] until you discover it somehow.

== Generation ==

The game generates doors as part of dungeon creation.

You can create a door in an empty doorway by zapping a [[wand of locking]] or casting {{spell of|wizard lock}}. You can also create a door in any destroyed bit of wall that connects a room to a corridor.

There are numerous ways to break a door, leaving a broken door, or destroy a door, leaving an empty doorway.

== Opening ==

Unlocked doors are opened using the [[open|open command]] ({{kbd|o}}), or by simply moving into them if the [[Options#autoopen|autoopen]] option is set to TRUE. Locked doors can be passed in a variety of ways:
* Unlocking by [[apply]]ing a [[skeleton key]], [[lock pick]], or [[credit card]] to the door. In [[Minetown]], if unlocking takes you more than one turn, you may receive a [[Watchman#Angering the watch|warning from a watchman]] if they are present.
* [[Zap]]ping a [[wand of opening]] or [[spellcasting|casting]] the {{spell of|knock}} spell at it. This unlocks the door but does not open it.
* Applying the blessed [[Bell of Opening]].
* Breaking or destroying the door with force. You should not do this in [[Minetown]] when [[watchman|watchmen]] or their [[watch captain|captains]] are present. Nor should you do this to [[shop]] doors. Note that doors with "[[shop#Closed shops|Closed for inventory]]" written in the dust next to them are locked doors to shops. Forecful methods are:
** [[Kick]]ing. This is [[noise|noisy]].
** Zapping a [[wand of striking]],{{refsrc|src/zap.c|3436|version=NetHack 3.6.7}}{{refsrc|src/lock.c|1018|version=NetHack 3.6.7}} [[wand of fire]], [[wand of lightning]], [[wand of cold]],{{refsrc|src/zap.c|4622|version=NetHack 3.6.7}} or [[wand of digging]]{{refsrc|src/dig.c|1505|version=NetHack 3.6.7}}, or casting the equivalent spells: {{spell of|force bolt}}, {{spell of|fireball}}, {{spell of|cone of cold}}, or {{spell of|dig}}, destroying the door.  Striking and force bolt are [[noise|noisy]]; the other methods are not.
** Applying an [[axe]], [[pick-axe]], or [[dwarvish mattock]] on a door. A shop door will be "too hard" to chop into.

== Closing and locking ==
Open doors can be closed using the [[close|close command]] ({{kbd|c}}). Zapping a [[wand of locking]] at it will close (and lock) it.

Doors can be locked by [[apply]]ing a [[skeleton key]] or a [[lock pick]] to a closed door, casting the {{spell of|wizard lock}} spell, or by using a [[wand of locking]].

== Monsters getting through ==
Monsters can unlock locked doors if they are larger than [[Physical size|tiny]], have hands, and have a [[key]]. You might want to dispose of keys if you lock up the Minetown watch.
{{refsrc|src/monmove.c|819|nethack=3.6.7}}

Several monsters can get through any door, even a locked door.
* [[giant (monster attribute)|Giants]] can bust down doors.
* [[Tunneling monster]]s can bore through doors.
* [[Amoeboid]]s and [[fog cloud]]s can flow beneath locked doors.
* [[Vampire]]s can shapeshift into [[fog cloud]]s.
* [[Phasing]] monsters pass right through doors.
* The [[Rider]]s and the [[Wizard of Yendor]] can unlock doors even without a key.

Also, a monster with a [[breath weapon]] of fire, cold, lightning, or disintegration can destroy a door if their breath weapon hits the door. But they usually will not attack you if there is a door between you and them.

== Secret doors ==
Some walls are in fact secret doors, which can be discovered by [[search]]ing, brute force, or [[magic]].

Searching is done with the {{kbd|s}} key, and is aided by wearing a [[ring of searching]] or [[lenses]], or by wielding [[Excalibur]]. [[Luck]] affects the chance of searching successfully. Applying a [[stethoscope]] to a wall will always reveal whether it is a secret door.

The brute force method involves [[kick]]ing at walls, applying a [[pick-axe]], or zapping {{spell of|force bolt}} at a likely position where a secret door might be. This consumes time and is often dangerous.

The magical method involves using a [[wand of secret door detection]], the spell of {{spell of|detect unseen}}, or the [[Bell of Opening]]; these will immediately reveal any nearby secret doors.  A blessed [[scroll of magic mapping]] reveals secret doors on the entire level.

== Door traps ==

At level 5 and below, about 3% of non-shop doors are booby-trapped.{{refsrc|src/mklev.c|394|nethack=3.6.7}} A door trap does 1d(2+{{sfrac|level|2}}) damage, in addition to [[stun]]ning you, [[abuse|abusing]] [[strength]] and abusing [[constitution]].{{refsrc|src/trap.c|5171|version=NetHack 3.6.7}} You can check a door for traps with the [[untrap|#untrap]] command. {{refsrc|src/trap.c|4581|version=NetHack 3.6.7}}

== Strategy ==

=== Avoid destroying doors ===

Kicking down a door makes [[noise]]. So does a [[wand of striking]] or [[spellbook of force bolt|spell of force bolt]]. Even if you use a quiet way to destroy a door, then you still don't have a door to use later.

If you find a locked door and don't have an unlocking tool then first try going around it.

=== Use doors to get out of combat ===

A closed door, even an unlocked one, is a good way to get out of a fight for a while -- especially in the early game.

An open door does not allow either monsters or you to pass through diagonally. This can be a great advantage when fighting multiple foes. A door like the entrance to the [[treasure zoo]] at the top of [[Sokoban]] can become a killing ground for monsters who will stream through one by one, allowing you to avoid some of their ranged attacks. Beware of wands and breath weapons, though!

=== Untrap the door to the [[Sokoban]] zoo ===

Very few doors have booby traps. But there are dozens of monsters on the other side of that door, so it is worth a few turns attempting to untrap the door so that you do not wake them up while stunning yourself in the process.

(Also, because of the way dungeon levels work, the real level of a Sokoban level is higher than the level displayed on the status bar. The level with the zoo is much higher than the threshold for booby-trapped doors.)

=== Exercising strength ===

Opening and closing doors exercises your [[strength]] every time the door resists. However, this technique is of little practical use.

=== Upcoming changes to door messages ===

{{upcoming|NetHack 3.7.0|Some of these messages have changed.}}

== Variants ==
=== SLASH'EM ===
In [[SLASH'EM]], doors can be [[force]]d open the same way chests can.

=== xNetHack ===
In [[xNetHack]], secret doors are less likely to appear on earlier dungeon levels; they will not appear at all before level 4.

xNetHack introduces iron doors, which cannot be destroyed by most brute-force methods (such as kicking and force bolts). These occasionally replace ordinary doors as the player reaches deeper dungeon levels.

The stunning door trap is replaced by a variety of traps with effects such as [[wet]]ting your inventory, [[burn]]ing your hands or gloves, or creating [[noise]] with screechy hinges. The full list is found at [[xNetHack#Trap changes|xNetHack § Trap changes]].

== Encyclopedia entry ==
{{encyclopedia|
Through me you pass into the city of woe:
Through me you pass into eternal pain:
Through me among the people lost for aye.
Justice the founder of my fabric mov'd:
To rear me was the task of power divine,
Supremest wisdom, and primeval love.
Before me things create were none, save things
Eternal, and eternal I endure.
All hope abandon ye who enter here.
|[ The Inferno, from The Divine Comedy of Dante
                 Alighieri, translated by H.F. Cary ]
