A '''katana''' does d10/d12 damage against small/large monsters, with a +1 bonus to hit. When unidentified, it appears as a '''samurai sword'''; [[samurai]] start with one. The sole artifact katana is [[Snickersnee]].

A '''katana''' is a type of [[weapon]] that appears in ''[[NetHack]]''. It is a one-handed weapon that uses the [[long sword]] [[skill]]. It is made of [[iron]], and appears as a '''samurai sword''' when unidentified.

The only differences between katanas and [[long sword]]s are the +1 bonus to hit and the katana's 1d10 damage vs. small (as opposed to 1d8 for a long sword). Because the katana is the most damaging non-artifact weapon to use the long sword weapon skill, it is often a desirable off-hand weapon for [[Twoweapon|two-weapon combat]].

Katanas are rare, very rare. In fact, only 4 in 1000 (0.4%)<ref>http://www.steelypips.org/nethack/343/weap-343.html#table1</ref> of all randomly spawned weapons will be a katana, making it the seventh rarest weapon in the game—a slot it shares with the [[lance]], among several others less notable. This makes getting one for most classes largely dependent on random chance.

All Samurai start the game with a +0 katana.{{refsrc|src/u_init.c|134|version=NetHack 3.6.7}}

As noted above, Samurai start with one in their initial inventory, and a Samurai hoping to #[[twoweapon]] should generally keep their original, as they're quite rare; should anything happen to it, it's possible to get another during the [[samurai quest]]. [[Bones]] from a Samurai are another chancy way to get a katana. Otherwise, for all classes, it may be worth spending a [[wish]] to get one. While there are several monsters that spawn with a special chance of a katana in their inventory, they're all located on the samurai quest. Considering that [[reverse genocide]] never spawns monsters with items, no help there. And one shouldn't waste genocide scrolls attempting.

−
One good place to look is the [[Castle]] stores—collectively, there is a decent 5.46% chance of finding one there. [[Death drop]]s are another small chance of getting a katana—in [[Gehennom]], where weapons are spawned with about 20% of all items, there is about a 0.0136% chance that a given monster will have a katana in their inventory. At such minuscule odds, however, one must slay ~2115 creatures to be even 25% confident to pry one from their cold, dead, slimy hands.

<!-- 2115.165511966 monsters in Gehennom for 25% confidence -->
 
−
 
 
−
Randomly spawned [[shop|stores]] are another—though by the time the player is worrying about acquiring one, they've likely gone through all the stores that the [[Dungeons of Doom]] has to offer. Late in the game, [[Orcus Town]] in particular has a small chance of having a katana spawned. The two general stores have a collective 3.15% chance of having a katana, assuming there are no mimics.

<!-- 3.150582134%, assumes that it follows normal spawning of items for Gehennom (20% weapons) -->

If the game has a portal to [[Fort Ludios]], each [[soldier]] has a guaranteed weapon, as well as the usual death drops. The 87 [[Yendorian army]] members there have a trivial ~0.59% chance of spawning a katana to plunder through death drops alone. However, the large number of weapons otherwise spawned may make it possible to [[polypile]] for the katana. To be 50% confident to attain a katana, one need polymorph 172.94 items—easily do-able with the 87 weapons assured to be there.

The table below relates the chance of getting a katana, assuming all the weapons are placed onto one pile, are uncursed, and the player has maximized their [[luck]], so as to lessen the chance of hostile iron golems. The confidence given is "overall," or "cumulative," meaning that if the player does not get it the first time, the odds do not increase, magically or otherwise.

Despite them making for the best long sword in the game, historically speaking, katanas were no better than an equivalent European sword<ref>http://tvtropes.org/pmwiki/pmwiki.php/Main/KatanasAreJustBetter</ref>. In the same era, while many katanas were better than European broadswords, this was simply because katanas were not mass produced (recall that Europe was often at war, and Japan quite isolated); in fact, owing to poorer quality steel in Japan, in a fairer comparison (non-mass-produced European sword) katanas were actually ''worse''. This is not a fault of NetHack, per se, as canonical [[Dungeons and Dragons]] from which NetHack is based.

It should be said, however, that due to the large number of [[Soldier|soldiers]] in the game, the long swords in NetHack are indeed most likely mass-produced. Furthermore, the +1 to-hit may be a nod to D&D, in that that is the exact bonus given to masterwork equipment. Although this still does not account for the fact that the stereotypically better Elven equipment, the [[Elven broadsword]], is still worse (on average) than a katana.

The primary differences between a katana and a long sword are the +1 bonus to hit, the katana's d10 damage to small monsters (as opposed to d8 for a long sword), and the inability to convert a katana into [[Excalibur]] by [[dip]]ping. The katana is also the most damaging non-artifact weapon to use the long sword weapon skill, and is often sought after as an off-hand weapon for [[twoweapon]] combat.

The ''katana'' is the name used for a Japanese sword characterized by a curved, single-edged blade with a circular or squared guard and a long grip to accommodate two hands. The term originates in the early 8th century CE and refers to single-edged swords in general, with the ones used by lower-ranking samurai and the like known as ''uchigatana'' (打刀). Despite the katana's modern reputation as a superb weapon, it was reserved for close combat, and only became commonplace as a weapon during the portion of the 16th-century Sengoku period where tactics changed and began to favor group battles by large groups of mobilized foot soldiers - the quality of [[steel]] in Japan was also relatively poor at the time of the katana's initial exportation.

A katana is a type of weapon that appears in NetHack. It is a one-handed weapon that uses the long sword skill. It is made of iron, and appears as a samurai sword when unidentified.

A Samurai wielding a katana has a chance of performing a shattering blow, destroying a monster's wielded weapon.

The katana is the base item for the artifact Snickersnee.

Generation

All Samurai start the game with a +0 katana.[1]

1⁄250 of all randomly generated weapons will be katana.

Player monsters, including those generated on the Astral Plane, have a 1⁄290 chance of being generated with a katana as their initial weapon before role-based replacements.[2] Samurai have a 1⁄2 chance of forcing a katana in place of their initial weapon.[3]

The following information pertains to an upcoming version (NetHack 3.7.0). If this version is now released, please verify that it is still accurate, then update the page to incorporate this information.

As part of commit 20cbadcf - which strengthens quest leaders and makes it so that killing them no longer makes the game unwinnable - the Samurai quest leader Lord Sato generates with a +4 katana.

Strategy

The primary differences between a katana and a long sword are the +1 bonus to hit, the katana's d10 damage to small monsters (as opposed to d8 for a long sword), and the inability to convert a katana into Excalibur by dipping. The katana is also the most damaging non-artifact weapon to use the long sword weapon skill, and is often sought after as an off-hand weapon for twoweapon combat.

Average damage calculation

The average damage calculations in the following table do not include bonuses from weapon skills, strength, or from using a blessed weapon against undead or demons.

Weapon Small monsters Large monsters
+0 katana \frac{1+10}{2}=\bold{5.5} \frac{1+12}{2}=\bold{6.5}
+7 katana \frac{1+10}{2}+7=\bold{12.5} \frac{1+12}{2}+7=\bold{13.5}

History

The katana first appears in NetHack 1.3d. From this version to NetHack 2.3e, the now-defunct Ninja role starts with a katana.[4]

In NetHack 2.2a and 2.3e, Snickersnee can be created by naming any katana.

Origin

Wikipedia
Wikipedia has an article about:

The katana is the name used for a Japanese sword characterized by a curved, single-edged blade with a circular or squared guard and a long grip to accommodate two hands. The term originates in the early 8th century CE and refers to single-edged swords in general, with the ones used by lower-ranking samurai and the like known as uchigatana (打刀). Despite the katana's modern reputation as a superb weapon, it was reserved for close combat, and only became commonplace as a weapon during the portion of the 16th-century Sengoku period where tactics changed and began to favor group battles by large groups of mobilized foot soldiers - the quality of steel in Japan was also relatively poor at the time of the katana's initial exportation.

The statline for the katana, including the +1 to-hit bonus, is derived from Dungeons & Dragons.

Variants

dNetHack

In dNetHack and notdNetHack, the katana gains a 50% strength-based bonus to odamage when wielded without a shield or offhand weapon.

Maids have a 1⁄4 chance of generating with a katana if the player character is a Samurai, and a 7⁄10 chance otherwise. dNetHack also introduces Kiku-ichimonji, an artifact katana that replaces Snickersnee (which is changed to a knife) as the Samurai's first sacrifice gift.

A blessed +3 katana named Sasuke's Blade can be found in the hidden westernmost room of the Fire Temple within the Chaos Temple Quest.

The November NetHack Tournament

In The November NetHack Tournament, all devteam members have a 1⁄2 chance of being generated with a katana.

The deathmatch opponent will always generate with a blessed erodeproof katana enchanted from +5 to +7 if they represent a samurai character that does not have a weapon.

SpliceHack

In SpliceHack, extraplanar merchants have a chance of generating with a katana.

EvilHack

In EvilHack, the katana has a base object material of steel. Ronin that appear on the Samurai quest have a 3⁄4 chance of generating with a katana.

A katana can be created at a forge by combining two long swords, and a katana can be combined with a two-handed sword to create a tsurugi.

SlashTHEM

In SlashTHEM, Nightingale is an artifact katana that is the guaranteed first sacrifice gift for the revived Ninja role. Kiku-ichimonji retains its role from dNetHack as the Samurai's first sacrifice gift, and Snickersnee is still present.

Encyclopedia entry

The katana is a long, single-edged samurai sword with a
slightly curved blade. Its long handle is designed to allow
it to be wielded with either one or two hands.
