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 ability to kick players from the Clan Chat; 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.
Bosses[edit | edit source]
Rewards[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 what common rewards are given and the quantity of these 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.
For example, if a player has 25,000 points and received ranarr weed drop and uncut rubies, they would get coins worth of ranarr weed and uncut ruby, which works out to be 30 ranarr weeds and 88 uncut rubies. This has not been proven, but has been inferred by looking at the value of drops and the points received.
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.
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 for players completing a challenge mode raid.
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%)||56,928,508|
|Arcane prayer scroll||4,179,246|
|Twisted buckler||4 (5.80%)||5,496,374|
|Dragon hunter crossbow||114,529,641|
|Dinh's bulwark||3 (4.35%)||4,597,346|
|Ancestral robe top||56,897,636|
|Ancestral robe bottom||57,919,933|
|Elder maul||2 (2.90%)||11,654,974|
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, we will 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.
