Temple of Ikov
By Eeeeediot
You will need to have started the Temple of Ikov quest to gain access to all areas of this dungeon, which is members only. Located in the middle of Kandarin, it's main entrance lies north-east of Ardougne and south-west of Catherby, adjacent to the Sorceror's tower. You initially come down the ladder at the far south of the dungeon. The alternative entrance/exit is at the far north (useable after you finish the quest) and this ladder leads you out to a room next to McGrubbor's woods close to Seers' village. You will need the shiny key to exit this room, and this respawns as shown on the map.
From the south ladder, you will need to be wearing Lucien's pendant (from quest) to go through the gate to your north into the room of fear. To cross the bridge to the west from there you will need to have a negative weight (achieved by only wearing the boots of Lightness). This dungeon is most commonly used by people training their combat slaying Skeletons and Lesser Demons. It is worth noting that once you have completed the quest, Windelda the Witch will always teleport you from the south side to the north side if you ask her.
