Missiles in NetHack come in two forms. Those that are shot from a missile launcher, and those that are thrown.
The shot missiles are:
- arrows, shot with bows
- crossbow bolts, shot with a crossbow
- stones, including flint stones, rocks, and gems, shot with a sling
The thrown missiles are:
The shot missiles can also be thrown in the absence of a launcher, but they will be less effective.
Arrows, crossbow bolts, darts, and shurikens may disappear when thrown. Blessing missiles lowers the chance of them disappearing after they've been fired/thrown by an amount that depends on your luck.
Valkyries can throw Mjollnir if they have 25 strength. It will return to them when thrown, usually returning to their hand, but more likely falling at their feet or hitting them if they are confused, stunned, or hallucinating.
