A helmet is a type of helm that appears in NetHack. It is made of iron and has a randomized appearance when unidentified[1][2]—the default one associated with it is a "plumed helmet".[3]

Samurai know the helmet as a kabuto.[4]

Generation

Knights start each game with a +0 helmet.[5] Knights and all other martial roles–Barbarians, Monks, Samurai, and Valkyries–begin the game with knowledge of its randomized appearance.[6][7][8][9][10] An elven, orcish or dwarven hero that would start the game with a helmet will start with an appropriate racial helm instead (i.e. an elven leather helm, orcish helm or dwarvish iron helm, respectively), but there are no applicable roles where this substitution occurs.[11][12][13]

Helmets make up 1⁄100 (1%) of all helms that are randomly generated on the ground, in general shops or as death drops. Used armor dealerships and antique weapon outlets can also stock helmets.

Mercenaries have a 2⁄3 chance of being generated with helmets that count for 1 point of their total AC.[14]

Player monsters, including those on the Astral Plane, have a 35264 chance (~13.26%) of generating with a helmet as their initial helm before role-based replacements, with cases that can affect this initial helm selection listed below:[15][16]

  • Player monster healers and clerics each have a 3⁄4 chance of their initial helm being replaced with a helm of brilliance or helm of telepathy, lowering their effective odds of retaining the helmet to 351056 (~3.31%).[17][18]
  • Player monster wizards have a 3⁄4 chance of their initial helm being replaced with a helm of brilliance, lowering their effective odds of retaining the helmet to 351056 (~3.31%).[19]

Description

While worn, a helmet grants 1 base AC plus any additional properties from its randomized appearance. As a metallic helm it hinders spellcasting for the hero, but it also protects a hero or monster wearing it from most damage inflicted by falling objects such as a triggered falling rock trap, a piercer attack, or boulders dropped by a read scroll of earth.[20]

Strategy

Standard helmets are the most unremarkable of the randomized helms: they are sufficient as a basic source of AC and head protection, but players will often encounter the almost-identical orcish helm or the lighter dented pot first before they see a regular helmet. It may still provide a viable replacement for an existing helm if it is generated with a positive enchantment and/or has the appearance of a visored helmet, which offers eye protection.

Like most early helms, helmets are usually replaced by an elven leather helm or any of the other randomized helms in the later stages, due to the additional perks they offer—even a dwarvish iron helm can be a suitable upgrade due to offering more base AC.

Identification

Helmets can easily be distinguished from other randomized helms by their price and weight: they are the only ones to have a base cost of 10 zm, making price identification in a shop trivial even without buying or selling one. Helmets also weigh 30 aum, while the other randomized helms weigh 50.

History

The helmet first appears in Hack 1.0, and is given a randomized appearance in NetHack 3.0.0.

Variants

In NetHack variants where item weight is shown, the standard helmet is somewhat easier to identify (assuming that helm weights are unchanged).

SLASH'EM

In SLASH'EM, Undead Slayers have a 3⁄4 chance of starting the game with an equipment set that includes a +0 helmet, which will otherwise be replaced by a +1 pair of low boots[21][22]—elven and orcish Undead Slayers will have their helmet replaced with the appropriate racial helm using the existing substitution code.[23][24] Both Undead Slayers and Yeomen are also included in the group of martial roles that start the game with knowledge of armor, including the helmet's randomized appearance.[25][26][27][28][29][30][31]

Player monster knights are always generated with helmets.[32]

SporkHack

In SporkHack, gnomish heroes in roles that start with helmets have them replaced with gnomish helms.[33]

dNetHack

In dNetHack, a helmet grants 1 base AC and 3 base DR while worn. If it is randomized to a band, it will appear as a "circlet".

Half-Dragon Anachrononauts start each game with an uncursed +0 copper helmet. Non-silverfish Knights start each game with a non-cursed +0 helmet, as do Samurai. Barbarians and Kensei start with knowledge of the helmet's randomized appearance, as do Knights and Samurai.

Many monsters can be generated with helmets—the full list can be seen via the "Details" tab.

SpliceHack

In SpliceHack, a helm of telepathy can be created at a furnace by combining a standard helmet and an amulet of ESP.

notdNetHack

In notdNetHack and notdNetHack, in addition to dNetHack details, Berith generates with a golden artifact helmet known as The Crown of Berith when summoned by an Illithanachronounbinder.

EvilHack

In EvilHack, giant Barbarians and Cavepeople receive a helmet in place of the role's standard initial armor.

Flinds have a 1⁄4 chance of generating with a helmet, and shopkeepers have a 1⁄4 chance of generating with a helmet; Croesus has a 1⁄2 chance of generating with a golden helmet, and Kas is always generated with a helmet. Mercenaries will often generate with helmets unless they are drow, elves or orcs, and the helmet also appears in the kits of various player monsters, particularly lower-level ones.

A helmet can be created at a forge by combining a dented pot and a dagger. Helmets can be used to forge several items:

SlashTHEM

In SlashTHEM, in addition to SLASH'EM details, Paladins start the game with a helmet unless they are elves or dwarves, who will start with the appropriate racial helm in those cases.

Hack'EM

In Hack'EM, tortle Undead Slayers receive a toque in place of the standard helmet.

Padawans and Jedi trainers have a 1⁄4 chance of generating with a helmet. All details from SLASH'EM and EvilHack are applicable.

Encyclopedia entry

Kabuto

The kabuto is the helmet worn by the samurai. It was characterized by a prominent beaked front which jutted out over the brow to protect the wearer's face; a feature that gives rise to their modern Japanese name of 'shokaku tsuki kabuto' (battering-ram helmet). Their main constructional element was an oval plate, the shokaku bo, slightly domed for the head with a narrow prolongation in front that curved forwards and downwards where it developed a pronounced central fold. Two horizontal strips encircling the head were riveted to this frontal strip: the lower one, the koshimaki (hip wrap), formed the lower edge of the helmet bowl; the other, the do maki (body wrap), was set at about the level of the temples. Filling the gaps between these strips and the shokaku bo were small plates, sometimes triangular but more commonly rectangular in shape. Because the front projected so far from the head, the triangular gap beneath was filled by a small plate, the shoshaku tei ita, whose rear edge bent downwards into a flange that rested against the forehead.
