Location[edit | edit source]
The Chambers of Xeric are located on Mount Quidamortem, which can be quickly accessed via the Lovakengj Minecart Network. This will require the player to bring a minecart control scroll from Miriam and bring it to Stuliette on the mountain. Doing so requires the player to have earned 65% Lovakengj favour.
Otherwise, players will need to head to the Shayziens' Wall and make their way west to Mount Quidamortem; be wary of aggressive lizardmen and lizardmen brutes. For those arriving there without the mine cart system, speak to the Mountain Guide (who is located on the mountain next to Gnosi, Historian Duffy, and the Natural Historian) before leaving; doing so will establish a two-way transportation system between the mountain and the Shayziens' Wall.
Mechanics[edit | edit source]
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 Clan Chat; which other players may join by manually typing in the clan chat's name or by requesting to join the chat. Once everyone is ready, the leader should enter the chambers, where a starting room is located. The raid officially starts once the leader confirms that everyone is in the room; 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 multiple demi-bosses/resource/puzzle rooms, and a final boss in every raid. 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' energy when interacted with.
Communication and teamwork is needed for players to defeat the bosses and complete the raid.
Challenge Mode[edit | edit source]
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 is always linear, and has four floors due to all combat/puzzle rooms being featured.
Resources[edit | edit source]
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 and circumstances players may encounter two scavenger rooms on the floor. They are 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[edit | edit source]
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. While the spots are static, the spots containing plain fish and the cave snake change occasionally.
All the items required to capture bats and fish can be obtained from scavangers can be dropped by scavengers
Fishing[edit | edit source]
|Pysk fish (0)|| 1
|Suphi fish (1)|| 15
|Leckish fish (2)|| 30
|Brawk fish (3)|| 45
|Mycil fish (4)|| 60
|Roqed fish (5)|| 75
|Kyren fish (6)|| 90
Hunter[edit | edit source]
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.
|Guanic bat (0)|| 1
|Prael bat (1)|| 15
|Giral bat (2)|| 30
|Phluxia bat (3)|| 45
|Kryket bat (4)|| 60
|Murng bat (5)|| 75
|Psykk bat (6)|| 90
Farming[edit | edit source]
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|
Herblore[edit | edit source]
Potions can be dropped in small amounts by the bosses, though this should not be relied on to obtain them. Scavenger beasts drop Herblore secondaries.
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: Overload tier is capped based on your Herblore level and potions being used. For example, you cannot make Overload(+) without having 90 Herblore and Elder(+), Twisted(+), and Kodai(+) potions. If you have those potions but only have 75 Herblore, the combat(+) potions will downgrade one tier to create a normal Overload.

Storage units[edit | edit source]
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.
|Storage units||level||Planks required||Experience||Capacity||Capacity|
|Small storage unit||30||2||150||250||30|
|Medium storage unit||60||4||150||500||60|
|Large storage unit||90||6||150||1,000||90|
|Massive storage unit||99||8||150||1,500||120|
Bosses[edit | edit source]
- Ice Demon
- Lizardman Shamans
- Skeletal Mystics
- Vasa Nistirio
- Great Olm (final boss)
Reward system[edit | edit source]
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 no, 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.
If a member of a raid party leaves early, the points multiplier and difficulty for that raid will remain the same.
Gaining Points[edit | edit source]
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[edit | edit source]
Dealing damage within the Chambers of Xeric will reward the player with points based on damage dealt.
Storage unit[edit | edit source]
Building or upgrading the Storage unit will give 100 points per tier.
Shortcuts[edit | edit source]
Muttadile[edit | edit source]
Guardians[edit | edit source]
When a player steps between the Guardians, they will push the player away, dealing damage and awarding some points.
Cooking Food[edit | edit source]
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[edit | edit source]
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. 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[edit | edit source]
In the Jewelled Crab room, being targeted by one of the crabs used to bounce the floating crystal towards the static crystal will reward some points.
Ice Demon[edit | edit source]
When a player deposits kindling in the braziers in the Ice demon room, they are rewarded with points.
Thieving[edit | edit source]
When a player fills the trough with cave worms in the Thieving room, they are awarded a certain amount of points.
Tightrope[edit | edit source]
When a player uses the keystone crystal on the barrier in the tightrope room, some points are awarded.
Loot table[edit | edit source]
If the team does not roll into the unique drop table, players will obtain two random common rewards instead. The third slot is reserved for the dark journal if players do not have it already, and the metamorphic dust/twisted ancestral colour kit for players completing a challenge mode raid. If the dust is rolled, the beam of light will turn turquoise; if the ancestral colour kit is obtained, then the beam of light will turn yellow for the player(s) who obtained it.
If multiple unique drops are rolled by the same player after completion of a Challenge Mode raid, then the beam of light covering the chest will alternate between all appropriate colors.
Unique drop table[edit | edit source]
Upon the Great Olm's death, if a unique reward item is given, it will be announced in the game chat. The beam of light covering the chest will change from white to purple for the player(s) who obtained a unique reward.
For every 8,675 total points obtained, a 1% chance to obtain a unique loot is given. This chance is capped at 65.7% (570,000 points) - any further points will be sent to roll for a second unique loot. For example, a team who possesses 855,000 points in total has an 65.7% chance to receive a unique loot, and then a 32.85% chance to obtain a second unique loot. Up to three unique rewards can be obtained per raid, assuming that there are enough points to roll for them.
If no unique loot is obtained, random resources are chosen, with the player's points determining the quantity of the items they obtain. In groups of all sizes, a weighting system is added when a unique loot is rolled, based on the players' points. For example, a player who has 90,000 points is twice as likely to obtain a unique reward compared to a player with 45,000 points.
Once the game has chosen which player will receive the unique loot, an item is chosen from the table below. The higher the weighting, the more likely a player will receive that item.
Accessing this table is required in order to be eligible for Olmlet.
|Item||Weighting (% chance)||GE Price|
|Dexterous prayer scroll||20 (28.99%)||27,589,212|
|Arcane prayer scroll||1,323,265|
|Twisted buckler||4 (5.80%)||3,993,883|
|Dragon hunter crossbow||97,734,916|
|Dinh's bulwark||3 (4.35%)||4,225,150|
|Ancestral robe top||66,291,309|
|Ancestral robe bottom||80,110,829|
|Elder maul||2 (2.90%)||12,235,035|
The chance of obtaining a unique loot can be calculated by performing the following steps:
- Calculate the chance of receiving a unique loot (number of points/8,675)
- Convert the result by (dividing result by 100)
- Calculate the chance of receiving a specific unique loot by dividing the weight of the item by the sum of the total weights (Item weight/69)
- Multiply the first result with the second result.
For example, to calculate the drop rate of a pair of dragon claws if the team has 413,250 total points:
- Chance of receiving a unique loot: 413,250/8,675 ≈ 47.6%, or 0.476
- Chance of receiving dragon claws from table: 3/69 (or 1/23)
- 0.476*(3/69) = 0.020714, which equals a 2.0714% chance of receiving dragon claws.

Trivia[edit | edit source]
- 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.
