A '''crysknife''' is a [[weapon]] produced by [[scroll of enchant weapon|enchanting]] a [[worm tooth]]. It has a +3 [[to-hit]] bonus and does d10 damage against both small and large monsters, making it a nice choice for #[[twoweapon]]ing. However, if it leaves your possession, it may revert back into a worm tooth.

Crysknives are not randomly generated. Aside from [[wish]]ing and [[bones]], the only way to create one is to wield a worm tooth and read a non-cursed [[scroll of enchant weapon]]. This will uncurse a cursed worm tooth, but won't increase the enchantment; thus, it's safe to re-sharpen a tooth regardless of how highly-enchanted it already is. A stack of worm teeth will merge into a single crysknife; to create multiple crysknives, you must split up the stack and enchant each one individually.

==Reversion==

Though crysknives count as throwing weapons, and get a to-hit bonus when thrown that makes them more powerful than even the rare [[shuriken]] and cumbersome [[boomerang]], their reversion property typically makes throwing them a bad idea. The material cost of creation and maintenance is generally prohibitive - it takes one scroll of enchant weapon to sharpen each worm tooth into a crysknife, plus one more scroll to fix the entire stack. On average, each crysknife will last 10 throws before having to be sharpened and fixed again.
If a crysknife leaves your inventory, it reverts to a worm tooth. Exceptions are if it goes into a container in your inventory or is stolen by a monster, but in those cases it will revert if the container leaves your inventory or the monster dies. The worm tooth retains the crysknife's enchantment.

The crysknife is a weapon that appears in NetHack.

Generation

Crysknives are never randomly generated, though they can appear in bones files.

Description

A crysknife can only be created normally by reading a noncursed scroll of enchant weapon while wielding a worm tooth (though it is also possible to wish for one). This will uncurse the worm tooth if applicable, but does not increase the enchantment - thus, it is safe to re-sharpen a tooth regardless of its enchantment. A stack of worm teeth will merge into a single crysknife, so in order to create multiple crysknives, you must split up the stack and enchant each one individually.

If a crysknife leaves your possession, it reverts to a worm tooth - placing it in a container in your inventory will not revert it unless that container subsequently leaves your possession. If stolen by a monster, the crysknife will not revert unless it leaves their inventory (e.g. usually when the monster dies). The reverted worm tooth will retain the crysknife's enchantment.

Erodeproofing a crysknife will "fix" it; a fixed crysknife will only revert 10% of the time. Dropping a stack of crysknives will make a single roll for the entire stack, but throwing multiple knives will roll for each of them. A crysknife that reverts also loses its fixing.

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.

The crysknife is now made of bone.

Strategy

The crysknife's +3 to-hit bonus and consistent d10 damage against both small and large monsters makes it a nice choice for #twoweaponing.

Though crysknives count as throwing weapons, and get a to-hit bonus when thrown that makes them more powerful than even the rare shuriken and cumbersome boomerang, their reversion property typically makes throwing them a bad idea. The material cost of creation and maintenance is generally prohibitive - it takes one scroll of enchant weapon to sharpen each worm tooth into a crysknife, plus one more scroll to fix the entire stack. On average, each crysknife will last 10 throws before having to be sharpened and fixed again.

In addition, most roles that can advance in knife skill have better ranged combat options; Healers are the only role who can reach multishot 3 with knives, and magic missile would prove much more practical and potentially more powerful for them.

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 Average damage
+0 crysknife \frac{1+10}{2}=\bold{5.5}
+7 crysknife \frac{1+10}{2}+7=\bold{12.5}
+9 crysknife \frac{1+10}{2}+9=\bold{14.5}

Origin

The crysknife is from Frank Herbert's science fiction novel Dune. This includes its fabrication from worm teeth and requiring "proximity to a human body's electrical field to prevent disintegration".

Variants

SLASH'EM

SLASH'EM changes the damage for crysknives to 1d20 against small and 1d30 against large; crysknives (and worm teeth) do not stack, so it is not possible to multishot them.

Yeomen can gain basic skill with knives; Ice Mages, Flame Mages, and Necromancers can become skilled; and Healers can become expert. A Healer can benefit seriously from the crysknife; since they have little weapon choice other than darts, a crysknife could be their most lethal weapon choice.

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

+7 crysknife \frac{1+20}{2}+7=\bold{17.5} \frac{1+30}{2}+7=\bold{22.5}

Encyclopedia entry

[The crysknife] is manufactured in two forms from teeth taken
from dead sandworms. The two forms are "fixed" and "unfixed".
An unfixed knife requires proximity to a human body's
electrical field to prevent disintegration. Fixed knives
are treated for storage. All are about 20 centimeters long.
