The Fremennik Slayer Dungeon is a dungeon located southeast of Rellekka, featuring monsters that can only be killed by those skilled in the Slayer skill. The monsters get progressively harder as the player goes deeper into the dungeon. It was released during the Slayer Skill update on 26 January 2005.
Players may use the portals inside one of the chambers on the lower floor of the Desert Slayer Dungeon (assuming that they have fought at least one of the bosses.)
Players may use enchanted Lyre to teleport south of the entrance to Rellekka and then walk the rest of the way.
If players have started the Giant Dwarf quest they may travel to Keldagrim via the Grand Exchange or the dwarven mines and head south.
Players may teleport to Camelot (or Seers Village, after Hard tasks) and travel the road that leads north, taking a left at the first fork, which leads you towards Rellekka.
Note: Everything but the Kurask and Cave Crawlers are unaggressive (although the Cave Crawlers are only aggressive to players with a Combat level of 46 and below). Cannons cannot be used in this dungeon because the air in the tunnel is too "humid".
This dungeon contains several slayer monsters, each with its own chamber.
The first chamber contains eight Cave Crawlers (level 10 Slayer is required to kill them). This chamber also contains an Agility shortcut which, at level 81 Agility, can be used to enter the Pyrefiend area. These are level 23.
The second chamber contains seven Rockslugs - level 20 Slayer and a Bag of salt are required to kill them. These are level 29.
The third chamber contains seven Cockatrice. They require level 25 Slayer and a Mirror shield - without one, the player's stats (including life points) will be dangerously reduced. Furthermore, they commonly drop level 2 Clue scrolls. These are level 37.
The fourth chamber contains thirteen Pyrefiends which can be killed at level 30 Slayer. They attack with a magic-based melee attack; therefore, wearing dragonhide or other high magic defence armour would be wise. The Agility shortcut here requires level 81 Agility, and leads back to the first chamber. Like Cockatrice, these also drop level 2 Clue scrolls. These are level 43.
The fifth chamber contains eight Basilisks which require level 40 Slayer and a Mirror shield to kill. There is a small safe spot against the southeast wall. (The safespot spans multiple squares, and can be utilized by standing directly adjacent to the zigzag pattern.) From there, a player can safely attack any Basilisk to the north. Engaging with a southern Basilisk will allow them to reach the player. With level 62 Agility the player can use the agility shortcut to enter the Turoth (seventh) chamber. Also, upon entering this chamber, the music will change from The Slayer to Masquerade. These, like cockatrices and pyrefiends, drop level 2 clue scrolls. These are level 61.
The sixth chamber contains ten Jellies, which require level 52 Slayer to kill. As with Pyrefiends, their attack is magic-based melee, so wearing dragonhide is strongly recommended. All monsters beyond and including these can drop level 3 Clue scrolls. These are level 78.
The ninth and final chamber contains a number of Aquanites. They require level 78 Slayer to kill, and have the ability to turn off a player's protection prayer. They can drop an Amulet of ranging. Aquanites are not aggressive. These are level 114.
Trivia
When examining the cave entrance from the outside, the game text used to read, "Wow - it's a guinea pig! No, hang on, it's a cave." - a pun on "cavie". Now it reads, "It leads to a small cave."
The layout of the dungeon is backwards. One enters by walking east but then to progress through the caves, the player must go west.
You can see a portion of The Kendal's cave from the north side of the Cockatrice area.File:Slayer cave entrance glitch.pngAn item floating above the cave's entrance.
Dwarf Cannons cannot be setup in this Cavern, yielding the response "The humid air in these tunnels won't do your cannon any good!"
There was a (now fixed) glitch where if you dropped an item immediately outside the dungeon entrance, it would float high in the air.
Kurasks used to be the strongest monsters in the dungeon until the Aquanites were released.
Most of the monsters drop white/gold parts of the Mystic set.
