Door

Version 0.18: This article may not be up to date for the latest stable release of Crawl.

A wooden door.

Doors are Dungeon features which are usually used to separate rooms from each other, though they may be found standing in the middle of a room as well. Found in the Dungeon and almost all branches, they are set into walls and are usually only 1x1 or 2x1 in size (though some vaults may contain far more massive doors). Walking into a door will open it, while pressing C when adjacent to one will close it. If you know that there are monsters behind a door, leaving it closed will keep them at bay unless they are aware of you and are intelligent enough to open the door, or they are capable of simply eating the door, in which case it will do you very little good.

Doors may occasionally creak when opened, alerting nearby monsters to your presence. This is less of an issue for heavily armoured bruisers than for stealthy sorts, as they tend to wake up everything no matter what. Fortunately, the chance of this happening is 1 in (8 + 4*Stealth/3), so stealthy characters are unlikely to cause it anyway. Silence also prevents creaky doors.

Runed Door

A door, covered in runic writing. It looks like there is something special behind it — perhaps danger, perhaps treasure. You may break the runes by opening it like any other door.

Runed doors are only found in special vaults, are indestructible, and are generally used to contain very powerful monsters and especially valuable treasure. Avoid opening them unless you're confident that you can handle something significantly out-of-depth. Clearing the rest of the floor first, just to minimize the risk of you running into more trouble as you flee or teleport away, is advisable, and don't forget that you can close the door again if that'll seal away the threat inside!

Note that random teleports and escape hatches from adjacent floors can still place you inside areas that are closed off by runed doors.

Runed doors are guaranteed to appear on level 2 of the Elven Halls, sealing the hall of blades.

Tips & Tricks

• Closing doors in front of monsters will delay them slightly even if they are able to open the door. If you are trying to buy time for one more MP or for a teleport to kick in, this can be a life saver.
• If you open a door and immediately see out-of-reach enemies capable of smiting you, tormenting you, blasting you with damnation, or otherwise dealing heavy damage at range, don't retreat! Running gives them the opportunity to attack you as long as you're in their line of sight. If you close the door first, this forces them to come to you, robbing them of several turns they could otherwise spend blasting you, and almost guarantees that you'll get to act against them first. This is effective against early threats such as orc priests, as well as late-game fiends and liches.
• Opening a door by hand will immediately reveal everything within that room. Blasting a door with a wand of disintegration will allow you to slowly bring the room into your line of sight, one step at a time. If you have reason to suspect that a door is hiding a particularly nasty vault, doing this will allow you to take on the contents a little bit at a time, rather than all at once (though it is rather noisy). Alternatively, shouting while near a door will awaken the inhabitants of the room beyond, and they may open the door for you a few turns later.

History

Prior to 0.12, there were occasionally secret doors that would only be revealed if you were within line of sight of them and succeeded on a check against your Traps & Doors skill. These were removed, which is why the skill was then renamed to Traps. These hidden doors used to be found everywhere, but were limited only to special vaults in 0.11.

A wooden door, cunningly hidden. It used to be a secret door, but, at least for you, it's not a secret anymore.

Runed doors were added in 0.12, although vault-defined warning-covered doors had existed for several versions before that.
