The Fremennik Slayer Dungeon, also known as the Rellekka Slayer Caves and the Fremennik Slayer Cave, is a cave system found south-east of Rellekka, featuring slayer monsters that can only be killed by players with the appropriate Slayer level. The monsters within require progressively higher levels as the player travels deeper into the caves.

Players cannot set up a dwarf multicannon within the caves. Attempting to do so yields the chatbox message: The air is too dank for you to set up a cannon here.

Transportation

The entrance to the Fremennik Slayer Dungeon is east of Rellekka and north-east of Sinclair Mansion (Show map). There are several ways to reach the cave:

Overview

Note: Everything but the kurasks and cave crawlers are passive (although the Cave Crawlers are only aggressive to players with a Combat level of 46 and below). Cannons cannot be used in this cave because the air in the tunnel is too "humid".

This cave contains several slayer monsters, each with its own chamber.

  1. 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 43 Agility[boostable], can be used to enter the pyrefiend area. These are level 23.
  2. The second chamber contains seven rockslugs - level 20 Slayer and a bag of salt or brine sabre are required to kill them. These are level 29.
  3. 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 medium clue scrolls. These are level 37.
  4. 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 43 Agility, and leads back to the first chamber. Like cockatrice, these also drop medium clue scrolls. These are level 43. For players using magic and ranged, there is safespot near rocks on west.
  5. The fifth chamber contains eight basilisks which require level 40 Slayer and a mirror shield to kill. There is a small safespot against the west wall, one square north of the agility shortcut. (The safespot spans multiple squares, and can be utilised 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 61 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 are level 61.
  6. 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 hard clue scrolls. These are level 78.
  7. The seventh chamber contains twenty two turoths, requiring level 55 Slayer to kill. They are immune to all attacks not dealt via leaf-bladed weaponry, broad arrows, broad bolts or the Magic Dart spell. The Agility shortcut requires level 61 Agility and leads back to the basilisk (fifth) chamber. The rocks on the east wall and the pathway to the kurask chamber may be used to safespot.
  8. The eighth chamber contains five kurask. They require 70 Slayer to kill. Like turoths, they are immune to all damage not dealt via leaf-bladed weaponry, broad arrows, broad bolts or the Magic Dart spell. These and the cave crawlers (in the first chamber, if you have combat level 46 or below) are the only aggressive monsters in this cave. There is a task-only area located above the steps. If players attempt to attack any of the kurasks upstairs without a kurask Slayer task, Jelly will forbid them from doing so.

You can no longer skip one of the shortcut obstacles in the Fremennik Slayer caves by interacting with a different obstacle.

8 May 2024
(Update)

Trivia

  • When examining the cave entrance from the outside, the game text reads, Wow – it's a guinea pig! No, hang on, it's a cave.. This is a pun on the scientific family name for guinea pigs, "cavy".
  • The layout of the cave is backwards. One enters by walking east but then to progress through the caves, the player must go west.
  • Most of the monsters in the cave drop pieces of the Light mystic robes set.
  • Similarly to the Slayer Tower, all monsters in the Fremennik Slayer Dungeon have a superior variant.
  • With some positioning, it was possible to pass the strange floor shortcut by only jumping over one of the traps but this has since been patched.
