An artifact weapon is a rare unique weapon, often with special properties. It may be acquired by sacrifice, by finding in a bones file, by finding in the dungeon, by wishing for one, or at the end of a quest. Excalibur may be acquired by dipping an ordinary long sword, provided you are lawful and level 5 and it hasn't already been generated. Excalibur, Vorpal Blade and Stormbringer may be acquired by praying with very good Luck; this is known as crowning.

An artifact weapon resists being wielded as a second weapon when #twoweaponing.[1]

Any artifact weapon given to you by your god will be noncursed and erodeproof, and you will be unrestricted[2] in the appropriate weapon skill if necessary. Certain roles are guaranteed to receive a particular weapon as their first gift[3]: Valkyries receive Mjollnir, Barbarians receive Cleaver, Wizards receive Magicbane, and Samurai receive Snickersnee.

Sunsword and Demonbane might be created in the possession of a humanoid angelic creature; Archons are sure to be generated with one. Sting and Orcrist may be created by #name'ing an ordinary elven dagger or elven broadsword.

Like all other objects, you may wish for an artifact weapon. There are some caveats:

  • If two or more artifacts have already been created, there is a chance that wishing for another will fail.
  • You cannot wish for your own quest artifact, and wishing for another class's quest artifact is only useful if it is of the same alignment as you - otherwise you will be unable to pick it up. If it is of your alignment, you can use it but it will blast you.
  • More generally, an artifact of the wrong alignment has a chance of blasting you every time you attempt to pick it up or wield it. Being blasted is not dangerous unless you are low-level (it only causes a small amount of damage) but it prevents you from picking the item up if it is intelligent. (To be precise, damage is 4d10 if the artifact is intelligent and 4d4 if not intelligent.)

Strategy

It is useful to obtain an artifact weapon that provides a bonus against most or all enemies, such as Excalibur, early in the game. However, wishing for one may not succeed if artifacts have been generated already (perhaps without your knowledge), and uses a valuable wish which normally could be used to considerably improve your defenses.

Selection

Because of the way that the odds of getting an artifact from a sacrifice reduce as more artifacts are generated, and the odds of getting an artifact from wishing becomes uncertain after two artifacts are generated in the game, artifact selection tends to be about acquiring the best artifact possible, rather than getting the perfect artifact, which may be either impossible or improbable.

Some artifact weapons, such as Giantslayer, only give a bonus against a narrow subset of monsters. These are nigh-useless; in practice by the time you see large numbers of giants (if you ever do), you'll have a better option. Receiving one as a sacrifice gift does unrestrict the relevant skill, which can be useful if you have a better artifact of the same type. Many variants try to improve artifacts of this type. Unfortunately there are quite a few artifacts that only give a narrow damage bonus.

A two-handed weapon means that you cannot use a shield, and in the late game it can become cursed, requiring you to #tip an uncursing item out of your bag to regain use of your hands. Intelligent artifacts resist curses, and holy water, scrolls of remove curse or the spell of remove curse can uncurse a two handed item. Use of a two handed weapon in the late game thus depends on available resources.

An intelligent cross-aligned artifact is unusable; an unintelligent cross-aligned artifact is potentially dangerous to use.

Some artifact weapons provide a useful resistance or other ability. For example, Stormbringer's level drain resistance means that you might wield it to clear the Valley of the Dead - it does no bonus damage to undead, but it essentially eliminates any threat they pose. Sunsword only deals bonus damage to undead, but can be useful as a light source.

Cleaver and Stormbringer are both dangerous to use around pets or neutral monsters you don't want to anger as they will attack without y/n confirmation.

Mjollnir, Fire Brand, and Frost Brand can destroy consumables that monsters are carrying. All things being equal, you would rather have those consumables for yourself, but all three of these weapons are also powerful.

Some artifact weapons give a bonus against most targets, like Fire Brand and Frost Brand. Very few monsters are energy resistant in the early game, and these monsters are rare in number and in frequency, meaning the weapon is useful except against resistant monsters. These weapons which damage a broad array of monsters can be used as part of an ascension kit. Energy resistant monsters are more of an issue in the late game as the high priest, the quest nemesis, Rodney, and the riders have some or all energy resistances. Wielding a highly enchanted regular weapon, or obtaining a second artifact for resistant monsters can be used in those instances.

A few artifact weapons, like Cleaver and Excalibur, give a bonus against all targets, applying their damage bonus universally. Especially noteworthy is Grayswandir, with double damage against everything and additional damage to targets harmed by silver.
