Leprechauns have intrinsic teleportitis, and approach you to try and steal any gold they see in your open inventory - they will otherwise keep their distance from you where possible. When you attack a leprechaun that is not frozen, asleep, confused, or blind, it has a 1⁄7 chance of moving one square away instead of being hit - this will cause you to "miss wildly and stumble forward" into that square.
Eating a leprechaun's corpse has a 50% chance of conveying teleportitis, the highest of any corpse in the game.
Leprechauns are normally generated sleeping, and will always carry LDd30 pieces of gold. Leprechaun halls are special rooms filled with sleeping leprechauns, with each one on top of a pile of gold in a similar manner to a treasure zoo.
When a leprechaun makes a successful gold-stealing attack, it teleports away. This can be avoided by using ranged attacks or attacking in melee while carrying no gold - keep in mind that they can steal gold directly at your feet, so it is best to bag it or stash it elsewhere.
While they are often harmless, they can use offensive wands against you, and can also generate with defensive items like a wand of digging that can make it difficult for you to recover your gold or the wand in question.
Amusingly, using a ring of conflict in a leprechaun hall will cause them to steal from each other—but it will soon prove annoying, as this scatters them across the level.
Leprechauns can be exploited for credit cloning: Drop all but one of your gold coins in a shop, then lure a leprechaun inside - once it picks up the pile of gold, then let it either steal your last gold piece or teleport out. Once you kill it to retrieve your gold back, you'll still have your credit - since you can only do this once per leprechaun, you should do it with as much gold as possible. Using leprechauns this way is difficult since they won't follow you, but it does mean you can credit clone even without a pet or a sack.
The leprechaun is among the many monsters present in the very first version of Hack by Andries Brouwer, along with "Hack for PDP-11" (which was based on an early draft). In early versions such as this and NetHack 1.3d, leprechuans used the L glyph and had slightly different behavior: they would still attempt to attack players that closed in as they attempted to keep their distance.
- You miss wildly and stumble forward.

- Your purse feels heavier.
- You stole some gold from a monster while polymorphed into a leprechaun.
The leprechaun (Irish leipreachán or luchorpán) is a diminutive supernatural being in Irish folklore, and is often classified as a type of solitary fairy; leprechaun-like creatures only became prominent in later folklore. They are usually depicted as little coat-and-hat-clad bearded folk with a tendency towards mischief, and were later portrayed as shoe-makers who have a hidden pot of gold at the end of a rainbow. The association with gold is often carried over to portrayals in media such as NetHack, where they always generate with gold.
SLASH'EM introduces the leprechaun wizard, a stronger form of the leprechaun that it can grow up into. They posses slightly better AC and the ability to cast clerical monster spells. Leprechauns can also hit as a +1 weapon.
In Slash'EM Extended, leprechauns are one of the many playable races, with similar abilities to vanilla leprechauns - they have teleportitis that cannot be controlled or lost, have increased chances of successfully #borrowing from monsters, and can steal gold with melee attacks. Several other leprechauns are added to the monster class as well, and will usually generate peaceful towards player leprechauns.
In xNetHack version 3.0, leprechauns were merged into the i imp or minor demon class, with xNetHack changing the glyph for the lizard monster class to lowercase l (l) instead to avoid using a punctuation glyph; this was reverted as of version 6.0.
Like other fey creatures, leprechauns are subject to bonus damage from iron weapons. Leprechauns are also capable of stealing gold items as well as gold pieces.
In dNetHack, leprechauns are among the many fey creatrues that take extra damage from iron weapons. The wards Thjofastafur, Elder Sign and the Cerulean sign can repel leprechauns; carving Thjofastafur into a weapon will cause that weapon to grant detection of them when wielded.
NetHack: The Next Generation
The Irish Leprechaun is the Faeries' shoemaker and is known
under various names in different parts of Ireland:
Cluricaune in Cork, Lurican in Kerry, Lurikeen in Kildare
and Lurigadaun in Tipperary. Although he works for the
Faeries, the Leprechaun is not of the same species. He is
small, has dark skin and wears strange clothes. His nature
has something of the manic-depressive about it: first he
is quite happy, whistling merrily as he nails a sole on to a
shoe; a few minutes later, he is sullen and morose, drunk
on his home-made heather ale. The Leprechaun's two great
loves are tobacco and whiskey, and he is a first-rate con-man,
impossible to out-fox. No one, no matter how clever, has ever
managed to cheat him out of his hidden pot of gold or his
magic shilling. At the last minute he always thinks of some
way to divert his captor's attention and vanishes in the
twinkling of an eye.
