Sunken Pyramid

The Sunken Pyramid is a dungeon home to The Order of the Slayer Masters, allowing players to become a slayer master. To enter the dungeon, players are required to have 99 Slayer. Players should bring a ghostspeak amulet or cramulet in order to speak to Faiza, but these items are not required if the player has completed the Hard Morytania Tasks.

If the player dies inside the pyramid, their grave will appear outside the entrance, where Portmaster Kags is.

Getting there
To travel to the pyramid, players may take a boat from Menaphos by speaking to Portmaster Kags on the south-western dock in the Ports district.

Players can also teleport there using the Slayer Codex if they have captured at least 50 different monster souls.

Chest of Souls
There is a Chest of Souls inside the pyramid that when clicked, makes a ghost named Faiza appear. She will inform players that they can become their own slayer master by capturing the soul of slayer monsters, and will provide them with 25-50 ushabti (the player's Slayer level determines the amount given), along with a Slayer Codex to keep track of slayer monsters that the player has captured.

Souls can be captured off or on a task. The chance of obtaining a soul increases when killing the monster on a slayer task, though it is not guaranteed to obtain one. There are a total of 146 monster souls that need to be captured. Players must have an empty ushabti to be able to capture souls from slayer monsters. Players are not required to possess or equip the Slayer Codex in order to capture souls. Capturing a soul rewards a small amount of slayer experience. Souls are automatically captured if eligible when the monster is killed.

In order to capture all 146 souls, players will need to have 117 Slayer (in addition to other requirements; refer to the monsters' page for other requirements). This can be boosted at 111 Slayer via use of wilder pie.

If a player clicks on the Chest of Souls with any number of filled ushabti in their inventory, all filled ushabti will be added to the Chest and cannot be recovered. Players wishing to add filled ushabti to their slayer dungeon must place them inside of the empty chambers.

Slayer Dungeon
Players can also choose to place the ushabtis in the empty chambers past the Chest of Souls.

There are three chambers that can house monsters, with each chamber holding up to 5 monsters of the player's choice. To place a monster spawn, enter building mode from the front door of the Sunken Pyramid not the game interface and then use the filled ushabti on one of the hotspots provided, similar to construction in the player owned house. Once confirmed, the monster will be placed, and will remain unless later removed by the player. Slayer experience will be awarded for placing the ushabti.

Monsters placed in these chambers will be the same as those found elsewhere, except that they will respawn within 4 seconds after being killed.

Much like the player owned house, players can visit other players' dungeons, provided that they have a monster in them. The owner does not have to be in the dungeon in order for others to enter; players can enter another's slayer dungeon as long as they are on the same world and have the appropriate friend settings on. Ironman accounts cannot enter another player's dungeon.

Some monsters cannot be placed in the dungeon. This includes wall beasts, Acheron mammoths and wyverns, due to their environment mechanics, as well as Lava strykewyrms. Other monsters can be placed, but will have certain restrictions, such as Edimmu, desert, ice, and jungle strykewyrms, which can be placed in the dungeon, but can only be killed if assigned as a task. Gemstone dragons will still require payment fees if not being killed on a task.

Some monsters that are normally aggressive in their original habitat, such as Edimmu, are not within the dungeon. Ripper Demons will not aggressively focus on the player if their health falls below 35% of their maximum if their souls are placed inside the dungeon. This does not apply to all aggressive monsters however, so it is unknown if this feature is intended or not.

Placing Automaton, Muspah or Nihil in the dungeon will randomly generate a variant of that monster. For example, placing an Automaton soul can generate a guardian, generator or tracer.

Trivia

 * The pyramid was first mentioned at RuneFest 2016.
 * Logging out in the dungeon lobby will place players outside the Sunken Pyramid.
 * Opening the door to the pyramid for the first time prompts the message: "You push at the door. At your touch, it opens and a hiss of air that smells hundreds of years old seeps out."
