Radiver's Dungeon

Radiver's Dungeon is a series of caverns that contains high level Slayer Monsters. Ranging from Airfiends to even White Dragons, this is one of the best and most dangerous places to train Slayer on RuneScape, Please be noted, that some sections contains multi combat zones.

To enter, talk to Radiver. There is no combat or slayer requirments, but he mentions to fully co-operate with the dungeon, you need 60 Combat and atleast 55 Slayer.

First Section
The first section of the dungeon contains the following: The room is Multicombat. Fortunally, all monsters in the room are non agressive unless you attack an Earthfiend which will call for Airfiends.
 * Airfiend
 * Waterfiend
 * Pyrofiend
 * Earthfiend
 * Icefiend
 * Holyfiend
 * Darkfiend

Trivia

 * It seems that Radiver Jonesta, the owner of the dungeon, like to keep in order with creatures, which is why instead of organized by level, he organized them by race. He did left a few exceptions though.
