The Chambers of Xeric are located on Mount Quidamortem, which can be quickly accessed via the Teleport Interface : Bosses -> Raids I: Chambers of Xeric.

Mechanics

Main article: Chambers of Xeric/Strategies

The Chambers of Xeric uses a unique party finding system to help determine how strong the team is. This will affect the strength of the monsters and bosses, in addition to the requirements needed in the skilling rooms. Players can bring their own supplies in (tools not needed), but will need to utilise the chambers' resources in order to defeat the increasingly strong bosses. Any number of players from 1 to 100 may start a raid.

To start a raid, the leader must create a team. This "team" is the leader's chat-channel; which other players may join by manually typing in the channel's name. Once everyone is ready, the leader should enter the chambers, where a starting room is located. The raid officially starts once the leader starts the raid; when that happens, all the mechanics will be calculated and no one may join the instance if they were not in by the time the raid started. If the leader leaves by any means, the next leader will be whoever has the highest rank in the Clan Chat, with a minimum rank of recruit; if no suitable rank is found, everyone is thrown out of the instance.

There are three floors in each raid; the final floor is always the same, housing the final boss. At the end of the first and second floors is an energy well that fully replenishes the players' run energy when interacted with. In normal-sized raids, each floor contains a mix of 2-3 combat/puzzle rooms; in large raids, each floor always contains four of these with the potential for duplicate puzzle rooms.

Communication and teamwork is needed for players to defeat the bosses and complete the raid.

Challenge Mode

Main article: Chambers of Xeric/Challenge Mode

Challenge Mode is a "hard" version of the existing Chambers of Xeric. All combat and puzzle rooms are featured and the enemies themselves have significantly increased stats. The layout of each floor is always static; due to putting all combat and puzzle rooms inside, teams must clear three floors with the general difficulty increasing as players venture deeper down.

Completion of the mode in a specific time frame can yield metamorphic dust to reskin an olmlet,twisted ancestral colour kit to recolour ancestral robes, and the Twisted Horns. Cosmetic capes are awarded at specific clear milestones.

Resources

The Chambers of Xeric have various resources which can be used in the raid to make things easier.

Scavenger beasts can be found around the dungeon. One scavenger room is always guaranteed somewhere in the raid, and it will always be before the first puzzle room. It is common to encounter one scavenger room on each floor, though in uncommon circumstances players may encounter two scavenger rooms on the floor. They are primarily killed for tool and Herblore secondary drops, which are used in the resource rooms, such as butterfly nets and cave worms.

The scavengers encountered are random, in addition to the room type they appear in - some rooms may be a small bend or curve, others a spacious area (which will always contain a boulder, mining rock or sapling shortcut which can be cleared away for points). The amount of scavengers in the room, along with their strength (to a very mild degree) is determined by the amount of players in the raid.

If the player dies in the Chambers, they will drop all raid-only items upon death; for example, if the player died with 10 Xeric's aid (+), those potions are dropped immediately upon dying. Other items that can be found, such as a hammer, will not be dropped upon death.

Food

All these cooking resources require the same level for hunting or fishing them, with the tier being determined by the team's overall Hunter/Fishing level. They are not often utilised in normal raids as Xeric's aid heals more per inventory space.

To catch bats, a butterfly net is required.

To catch fish, a fishing rod is required, with cave worms as bait. In fishing rooms, there are three fishing spots. One of these three spots contains a cave snake, which will damage the player (or take their fish). If a snake appears in the fishing spot, stop fishing and click elsewhere to avoid taking damage. Only spots containing plain fish and cave snakes will move occasionally.

All the items required to capture bats and fish can be dropped by scavengers.

Hunter

In resource rooms without fishing spots, there will be two to three bats flying around in the chamber, which can be caught and cooked for food. Players with 99 Hunter can catch any bats barehanded.

Farming

Seeds can be obtained from several bosses, such as the Skeletal mystics, Lizardmen shamans, and Guardian statues. They can also be found by raking weeds in the top and lower floors (the last area in those floors and the first area in the lower floor).

There are two farming plots in each resource room for players to grow herbs. Due to the magic of the chambers, herbs grow faster and are fully grown in 30 seconds.

Seed		Level	Planting XP	Harvest XP
File:Golpar seed.png	Golpar seed	27	4	10
File:Buchu seed.png	Buchu seed	39	6	15
File:Noxifer seed.png	Noxifer seed	55	12	30

Herblore

Potions can be dropped in small amounts by the bosses. Some bosses drop herblore secondaries, although they are primarily obtained from scavengers.

There are three types of potions a player can make:

• Golpar (combat potions)
• Buchu (recovery potions)
• Noxifer (overload-type potions)

To create potions in the chambers, a gourd must be collected from the nearby gourd tree, then filled with water from the nearby water spout or with Humidify. Gourds can be picked en masse with the "Pick-lots" option. Gourds automatically break upon drinking the last dose of the potion.

Note: Potion tiers are capped on the player's Herblore level upon creation and will downgrade accordingly for overloads; e.g a player with 80 Herblore would be able to make combat+ potions, but as overload+ requires 90 Herblore, they will downgrade into a normal overload upon creation.

Storage units

Storage units are built from mallignum root planks, obtained as drops from scavengers. A hammer is required in building storage units, with the dragon warhammer being a suitable substitute.

Once a storage unit is built, anyone can use it. Storage units have a shared and personal inventory. The shared inventory allows players to store items used in the raid, such as the tools, seeds, herbs, Herblore secondaries, and potions. The personal inventory is much like the shared inventory, but it can also hold the player's belongings, such as weapons and armour. The player can also put in raid-unique items in there if desired. In addition to this, once a storage unit is built anywhere in the Chambers, they will appear in all potential hotspots where they may be found.

Storage units can be found at the end of each floor, in addition to appearing in resource rooms, the corrupted scavenger, and ice demon chambers.

While higher levelled storage units can be built immediately, they still require the materials to build the previous tiers. So in order to build a large storage unit instantly, you need 6 planks (4 for the first two storage units, then 2 for the remaining upgrade).

Players who leave the Chambers with their personal items still stored in the storage units can retrieve them from the private storage unit next to the bank chest on the mountain. The private storage unit must be emptied before players can re-enter the Chambers of Xeric.

File:Small storage unit icon.png	Small storage unit	30	2	150	250	30
File:Medium storage unit icon.png	Medium storage unit	60	4	150	500	60

Bosses

A group of players fighting the Great Olm.

• Ice Demon
• Lizardman Shamans
• Muttadiles
• Skeletal Mystics
• Tekton
• Vanguards
• Vasa Nistirio
• Vespula
• Great Olm (final boss)

Reward system

Player rewards are based on "participation" points. As the team collects more points, they have an increased chance of obtaining unique items. Individually, these points determine the quantity of common rewards. If a player dies in a raid, they will lose 40% of the points that they had before their death. If the player dies with none, or extremely few, personal points, the team's overall points are reduced instead.

The current maximum amount of points attainable per player is 131,071 points. Additional points that would be earned by a player with maximum personal points are still added to the team's overall points.

If a member of a raid party leaves early, the points multiplier and difficulty for that raid will remain the same.

Gaining Points

Gaining points in raids is possible in multiple ways, all of which have a cap which scales to the number of players in the raid. Below is a short description for all ways to gain points within the Chambers of Xeric.

Combat

Dealing damage within the Chambers of Xeric will reward the player with points based on damage dealt.

Storage unit

Building or upgrading the Storage unit will give 100 points per tier.

Shortcuts

In some scavenger rooms, a shortcut which requires Mining, Woodcutting, or Strength to clear can be found. Clearing this shortcut rewards the player with some points.

Muttadile

In the Muttadile room, there is a meat tree. Cutting this tree awards some points.

Guardians

When a player steps between the Guardians, they will push the player away, dealing damage and awarding some points. This is the only method that does not have a point cap in the raid.

Cooking Food

A player is able to catch bats using Hunter and catch fish using Fishing within the Chambers of Xeric. When any player (including the person who cooked the food) eats them and heals damage, the player that cooked the food is awarded points. If a different player to the one cooking the food uses that food to heal, the player that cooked the food receives 50% more points than if they were to eat it themselves. Psykk bats found in the Thieving room count as food cooked by the player who found them.

Potions

Appropriate use of potions that the player makes will award some points to the player that made them or got them from one of the bosses. The points awarded are capped at 5 sips times the number of people participating in the raid, plus five extra at a reduced amount. More points are given if a player other than the one who created the potion drinks them. Overloads award the highest amount of points, so players should try to refrain from drinking other potions during the raid, as the point cap for potions is based on doses drunk, not points gained. 75 Herblore for overload, 90 Herblore for overload+.

Crabs

In the Jewelled Crab room, attacking or being targeted by one of the crabs (including ones not used to bounce the floating crystal) will reward some points upon each successful crystal colour change.

Ice Demon

When a player deposits kindling in the braziers in the Ice demon room, they are rewarded with points.

Thieving

When a player fills the trough with cave worms in the Thieving room, they are awarded a certain amount of points. Points stop being awarded when the scavenger no longer needs any more worms.

2 persons = 30 grubs

3 persons = 42 grubs

4 persons = 56 grubs

Tightrope

When a player uses the keystone crystal on the barrier in the tightrope room, some points are awarded.

Rewards

Main article: Ancient chest

A player receives a unique reward from the ancient chest.

Depending on the points obtained in the raid, players have a chance to obtain a reward from the unique drop table. If the player does not roll into the unique drop table, they will obtain two rolls of standard loot instead (which cannot both be the same loot), with their quantity depending on points obtained.

Regardless of whether a unique drop was obtained, players may always additionally obtain the dark journal if they do not have it already, and the metamorphic dust/twisted ancestral colour kit for players completing a challenge mode raid if successfully rolled on.

The beam of light above the chest will vary for the player depending on the loot obtained: by default, the light is white; if the player obtained an item from the unique drop table, it is purple; if the player obtained a metamorphic dust, it is turquoise; if the player obtained a twisted ancestral colour kit, it is green. If multiple such drops are obtained simultaneously, the light alternates between each appropriate colour.

Changes

Date	Changes
27 July 2022 (update)	For Ultimate Ironman players, any unclaimed Chambers of Xeric rewards may now be dropped outside the Chambers rather than being put in the private storage, since Ultimate Ironmen cannot use it.
9 December 2021 (update)	The minimum HiScores 'killcount' required for Chambers of Xeric Challenge Mode has been lowered from 10 to 5.
16 June 2021 (update)	Level scaling can be removed by talking to Captain Rimor. A default chest has been added to store 25 items for personal use. Antipoisons for the raid can be made inside. Vanguards can be damaged during their transition phase. Great Olm's fire wall attack can be extinguished with ice spells. A pickaxe spawn has been added to all Guardian rooms. More herbs can be harvested on average in larger raid sizes. Points scale linearly with combat level, allowing for more consistent point gains for players of specific levels. Challenge Mode's submerged Muttadile deals 20-80% of its maximum hit; this ensures more consistent damage, but avoids potential combos from both it and its young. Challenge Mode Vasa's crystals have had their challenge mode modifier removed. A Raid Party can receive up to six unique rewards from a raid if they earn enough points.
20 January 2021 (update)	Multiple graphical wall issues within a raid have been fixed.
13 January 2021 (update)	The Chambers of Xeric Party Board will now let you unselect the Challenge Mode option correctly.
11 November 2020 (update | poll)	Maps pools have been updated; the large pool now uniformly contain five combat and three puzzle rooms per raid. The regular pool now has equal amounts of small and medium raids. To complement this change, a secondary checkbox has been added to the Party Board outside the Chambers of Xeric that lets you toggle between regular and large map pools. Scavengers will spawn more consistently, with a preference for locations near players. When killing a scavenger, a message will appear that makes it clear who received the drop. If an Iron player deals the most but not all of the damage to a Chambers of Xeric boss, all other raiders will receive a message announcing that they have earned the drop.
16 July 2020 (update)	An issue in which players would be hit by Vespula's melee attack if the portal was closed has been fixed.
2 July 2020 (update)	An issue in which points were not being awarded in certain challenge rooms has been fixed.
18 June 2020 (update | poll)	A toggleable healthbar interface has been added to Tekton, Vespula's Abyssal Portal, Muttadiles, Vanguards, Vasa Nistirio and the Great Olm. For the Vanguards, the HUD will show each of their healthbars individually. Players can now right click the tool rack in resource rooms to select a specific tool.
28 May 2020 (update | poll)	The Vanguards have received additional changes. Players with higher Thieving levels will now have a chance of receiving multiple grubs from a chest. Potion drops now have a higher value, and are thus more likely to appear on top of the lootpile alongside raid supplies and bones. Players can now build an extra large storage chest with a capacity of 1,500. To make it, 99 Construction and 8 planks are needed. Players now have the chance to obtain the metamorphic dust again even if they have already previously obtained it in Challenge Mode. Unique rewards collected from the reward chest will now be given as items rather than banknotes.
21 May 2020 (update | poll)	The Vanguards have received several changes which aim to make the encounter less annoying while preserving its difficulty. Fastest completion times of both regular and Challenge Mode are now displayed in the adventure log. The loot table of scavenger beasts has been rebalanced to include a more reasonable amount of cicelies and endarkened juice. One of the possible orientations of the Jewelled Crab room has had its crystal positions altered. An issue in which players would be hit by Vespula's melee attack if the Abyssal portal has been destroyed has been fixed.
9 January 2020 (update)	Lizardman Shamans, Skeletal Mystics and Stone Guardians now tell the party which individual received the seed drops upon death, if applicable.
12 September 2019 (update)	Stun effects in the Chambers of Xeric can no longer be dodged by lighting fires.
14 March 2019 (update)	Enchant spells are no longer offered in the Chambers of Xeric, as the stat-boosts in there are unusually large and were not intended for getting oneself permanent access to items unrelated to the Chambers.
7 March 2019 (update)	NPC stats are now scaled based on the player with the highest combat stats rather than the average combat stats of all party members
28 February 2019 (update)	Trees found within the ice demon room in Chambers of Xeric are now less likely to fall. Players will now receive more wood than before when successfully chopping trees within the room based on Woodcutting level. As saplings can now give more wood than before, the Woodcutting XP gained per item of kindling has been reduced slightly. The ice demon's defences are now lower than before and its magic defence is now calculated from its defence level rather than magic, making it weaker to spells overall, including its additional weakness to fire spells. In Challenge Mode, the 5k bonus points are now added to the team's reward rather than individual party members. A bit of wall sticking out of one of the Skeletal Mystic's rooms in the Chambers of Xeric has been removed. Tweaks to the Vanguard's reset mechanic have been made to ensure they are reset correctly
14 February 2019 (update)	Great Olm's flame attack can now be doused with Humidify and vessels of water. Elite clue scrolls are now an additional reward instead of replacing the second reward. Monster Examine may now be cast on all monsters in the raid.
10 January 2019 (update | poll)	Dragon sword, dragon harpoon and dragon thrownaxe were removed from the drop table and moved to monsters in Karuulm Slayer Dungeon. This did not affect the rarity of other drops, as they were re-weighted.
17 May 2018 (update | poll)	Challenge Mode was implemented, providing a more difficult raid with every room in a static layout.
8 February 2018 (update | poll)	A bronze axe spawn was added in the ice demon room. Previously, a tinderbox was also added. Whenever a mini-boss is killed, a broadcast will go out to player as to who obtained its drops. The party interface now shows how many times the player has successfully completed the Chambers of Xeric. The three storage chests were modified to now require 2, 4 and 6 mallignum root planks respectively, down from 4, 8 and 15.
4 May 2017 (update)	Long bones, curved bones, and rune pouches can now be stored within raid private storage. Fixed an issue where the Muttadile would sometimes become permanently invincible.
23 February 2017 (update)	You now have a chance of receiving Elite clues from Raids. A notification is now given to the party if someone clears a farming patch in raid.

Trivia

File:Paradigm of Exodus.png

Concept art of the Paradigm of Exodus, a raid whose concept was later reshaped into the Chambers of Xeric.

• The Chambers of Xeric was originally proposed in 2014 as the "Paradigm of Exodus", a large dungeon found in and around an active volcano, allowing 5 to 30 players to take on powerful monsters and solving puzzles in a randomly generated layout, with a boss at the end of the raid.
