A crossbow is a type of launcher that appears in NetHack. It is designed for crossbow bolts, and should be wielded prior to throwing or firing them from your quiver, similar to a bow and arrows. Enchanting a crossbow only increases its to-hit rate, not its damage. Crossbows are made of wood.
All Gnomish Rangers start the game with a +1 crossbow rather than a +1 bow; crossbows and crossbow bolts are considered racial equipment for gnomes, though gnomish Rangers are the only case where this substitution applies.
Plains and mountain centaurs have a 1⁄2 chance of generating with a crossbow and 3–14 bolts. Crossbows can also be generated on any monster lacking the strong monster attribute that can use a weapon, but has not received one.
Crossbows always fire at their maximum range of 8 squares, rather than basing their range on strength as other missile weapons do. Instead, crossbows apply a multishot penalty if their user is below a certain strength threshold: gnomes must have at least 16 strength to obtain full multishot bonuses, while other races require 18 strength. Gnomes other than Healers and Wizards also gain a +1 multishot racial bonus when firing bolts from a crossbow.
High-strength characters lacking a ranged weapon may choose to retrieve a crossbow from the Gnomish Mines; ammo for the crossbow is somewhat scarce compared to arrows, which are much more commonplace due to the various arrow types and arrow traps. As with most launchers, you should enchant the bolts themselves (rather than the crossbow) in order to increase their damage; crossbow enchantment only affects their to-hit rate.
Gnomish Rangers may get additional crossbow bolts in the early game from gnomes, but may want to let a pet do the killing to avoid alignment record penalties. The centaurs in the Ranger quest provide a plentiful source during the midgame, but attack wands may be a problem without reflection or the relevant resistances. Their quest artifact, The Longbow of Diana, uses a different skill and ammunition that is incompatible with crossbows; a gnomish Ranger may prefer to keep their crossbow and a large stack of enchanted crossbow bolts as their primary ranged attack, and carry the Longbow only for the extrinsic telepathy.
In SLASH'EM, crossbows are two-handed weapons. SLASH'EM also introduces an artifact crossbow, Hellfire, that is chaotic-aligned and provides fire resistance when wielded; bolts fired from it that hit monsters create a fiery explosion in a 3x3 square centered on that monster.
Undead Slayers have a chance of starting the game with a crossbow and bolts.
In dNetHack, gnomish players are always given crossbows in place of regular bows. Gnomes get an extra die of weapon damage when firing crossbows, and player gnomes can attain Expert skill crossbow, regardless of role; The Rogue Gear-Spirits replaces The Longbow of Diana as the quest artifact for gnomish Rangers, and is obtained from the Gnomish Ranger Quest.
Crossbows no longer grant multiple shots at higher skill levels, instead increasing the damage dealt by a single crossbow bolt:
- Basic or lower: 1x (bolt+enchantment) damage
- Skilled: 2x (bolt+enchantment) damage
- Expert: 3x (bolt+enchantment) damage
In addition, each shot adds 3x the damage bonus from the current skill level (-5 Restricted, -2 Unskilled, +0 at Basic, +2 at Skilled and +5 at Expert). The extra damage is precision-based and does not apply against amorphous, stationary, or incorporeal monsters, which are assumed to lack discernible weak-points.
There are two other artifact crossbows:
- Hellfire, which is similar to its SLASH'EM incarnation and grants fire resistance alongside explosive bolts.
- The Unstoppable, which causes any bolts fired from it to continue flying until they hit a wall, piercing or else flying past enemies.
dNetHack also adds the droven crossbow, a type of crossbow commonly used by drow; lawful droven Nobles receive the artifact droven crossbow Liecleaver as their crowning gift, and Wrathful Spider is a quest artifact droven crossbow given to female droven Priests, Rangers, Rogues, and Wizards.
In GruntHack, crossbows now fire a set range regardless of strength, and require high strength to fire mulitple shots.
In EvilHack, Monks no longer have the crossbow skill available; centaurs gain a +1 multishot bonus when using crossbows. This means that centaur Monks can still fire 2 crossbow bolts per shot despite the skill being restricted.
Gnomish Rangers have their quest artifact changed to The Crossbow of Carl, which is an artifact crossbow that mirrors The Longbow of Diana given to other Rangers. This allows them to preserve their multishot bonuses while also giving access to an unlimited source of crossbow bolts.
For SlashTHEM, on top of SLASH'EM additions, Warriors start each game with a +1 crossbow and a stack of +0 crossbow bolts; Undead Slayers now have a 1⁄2 chance to start with a crossbow and some bolts. All player gnomes are capable of reaching skilled in crossbows.
In NetHack Fourk, gnomes have increased skill caps for crossbows.
