# The Sea (dNetHack)
In dNetHack, the Sea is accessed by a stairway down located between levels 5 and 25. Monster generation in the Sea is biased toward chaotic monsters. On entering the level, you will get the message "You hear the roar of the sea. That can't be right...."
In each game, one of the following possible variants of the Sea will be chosen.  In all cases, the main treasure is a guaranteed magic lamp, but all levels also contain an amulet of magical breathing.

The magic lamp is contained in a buried iron chest, along with some gold, random gems, an amulet of magical breathing, a second random amulet, two rings, and an oil lamp.
Up to 4 cursed figurines of powerful monsters are also buried on the island, and some random treasure is lost out at sea.
The island is initially populated by two tigers, 4 parrots, three monkeys, three crocodiles, three random snakes, and two giant spiders.  A large number of random sea monsters populate the ocean.
To find the chest, you will need a source of blessed magic mapping. Object detection will not show buried objects on this level, but blessed magic mapping will burn engravings on squares containing the chest and the cursed figurines. The figurines receive a lowercase "x", and the chest receives a "X" with slashes on the squares diagonally adjacent to it that point at the chest.
