Medusa's Island
Location Level 21–28 of the
Dungeons of Doom
Variants
Bones No
Mappable Yes
Teleportable No
Diggable floor Yes
Diggable walls varies

Medusa's Island is the home of Medusa. It is ineligible to leave bones files. The entire level is non-teleportable. It is 1 to 4 levels above the Castle and therefore between dungeon level 21 and 28. Monster creation on this level is biased towards chaotic monsters.

There are four different versions of the island, each of which has an equal chance of being used (prior to NetHack 3.6.0, only the first two existed).

First version

Medusa's Island (1)
Location Level 21–28 of the
Dungeons of Doom
Bones No
Mappable Yes
Teleportable No
Diggable floor Yes
Diggable walls No

Medusa is waiting on the down stairs; there is a random snake in each of the top and bottom corridors of her hall, two water trolls in the water to the right of the level, three giant eels and three jellyfish in the water to the left of the level, and ten random other monsters. In addition to the two marked squeaky boards, there are five other random traps on the level.

The statue of Perseus has (independently) a 75% chance of containing a cursed +0 shield of reflection, a 25% chance of +0 levitation boots, a 50% chance of a blessed +2 scimitar, and a 50% chance of a sack; up to five other statues of player-monsters with names and classes from the top ten score list may be randomly created in Medusa's chamber, and will be empty. The seven random other statues around the level will contain any equipment their monster type might usually be issued with, but will not have the usual chance of containing a random spellbook.

Second version

Medusa's Island (2)
Location Level 21–28 of the
Dungeons of Doom
Bones No
Mappable Yes
Teleportable No
Diggable floor Yes
Diggable walls Not on leftmost/
rightmost islands

Medusa is waiting on the down stairs; there are a titan and a gremlin in the entrance hall, six electric eels and three jellyfish in the water to the left of the level, four stone golems and two cobras immediately outside Medusa's room, a random A and a yellow light in the back room of Medusa's hall, and a further thirteen random monsters distributed fairly evenly across the level. In addition to the marked magic trap, there are four other random traps on the level.

The statue of Perseus has (independently) a 25% chance of containing a cursed +0 shield of reflection, a 75% chance of +0 levitation boots, a 50% chance of a blessed +2 scimitar, and a 50% chance of a sack; up to five other statues of player-monsters with names and classes from the top ten score list may be randomly created in Medusa's hall, and will be empty. The eight marked statues outside Medusa's room will contain any equipment their monster type might usually be issued with, but will not have the usual chance of containing a random spellbook.

There are marked boulders in the entrance hall and on the right-hand island; the latter has a random wand beneath it. The walls of both the entrance hall and Medusa's hall are undiggable.

The wand is possibly a reference to NetHack 2.3e and earlier versions of NetHack. These versions did not have the Castle; instead, they placed the wand of wishing in one of the upper mazes, in a dead-end square with a boulder on top.

Third version

Medusa's Island (3)

Dungeons of Doom

The up stairs are on the top-center island. Only one of the marked stairs is the actual down stairs with Medusa waiting on them; another is actually the statue of Perseus, and the third is actually a fountain. Thirty hostile ravens populate the level, as well as two giant eels, two jellyfish, two wood nymphs, and two water nymphs. Two scrolls of blank paper are at the marked location, as well as eight random items scattered around the level. Two rust traps, two squeaking boards, and one other trap are randomly placed. The rooms potentially containing Medusa have non-diggable walls, but the right half of the double room (excluding its left wall) is diggable, and trees may be chopped down.

The statue of Perseus has (independently) a 75% chance of containing a cursed +0 shield of reflection, a 25% chance of +0 levitation boots, a 50% chance of a blessed +2 scimitar, and a 50% chance of a sack; up to five other statues of player-monsters with names and classes from the top ten score list may be randomly created in Medusa's chamber, and will be empty. The seven random other statues around the level will contain any equipment their monster type might usually be issued with, but will not have the usual chance of containing a random spellbook.

The up stairs are on the islands on the right. Only one of the marked stairs is the actual down stairs with Medusa waiting on them; another is actually the statue of Perseus, and the other two are empty. The marked yellow dragon is generated asleep, and may have up to two babies sleeping by her. She also nests on one to three yellow dragon eggs, which may hatch (awake and hostile) by the time you reach them. Also inhabiting the level are two giant eels, two jellyfish, four each adult and baby black nagas, and 14 random snakes, which may include pythons as capable of drowning you as the eels. Eight random objects and seven random traps are randomly placed. The crystal ball below the kraken is underwater.

The statue of Perseus has (independently) a 75% chance of containing a cursed +0 shield of reflection, a 25% chance of +0 levitation boots, a 50% chance of a blessed +2 scimitar, and a 50% chance of a sack; up to five other statues of player-monsters with names and classes from the top ten score list may be randomly created in Medusa's chamber, and will be empty. The seven random other statues around the level will contain any equipment their monster type might usually be issued with, but will not have the usual chance of containing a random spellbook.

Note that depending on Medusa's position, you may catch sight of her through the iron bars; take the appropriate precautions before entering her complex.

Variants

UnNethack

As with other special levels in UnNethack, the four layout variations may be flipped horizontally, vertically, or both.

SLASHTHEM

A notable difference in SLASHTHEM, is the far greater number of sea monsters in the level (and other water levels). A few of these new sea monsters, have stealing and lycanthropy attacks.

You should be prepared with telepathy, or at least warning and ranged attacks.
