Mount Quidamortem stands as a towering landmark in the north-western reaches of the Kebos Lowlands within the kingdom of Great Kourend. For players of Old School RuneScape (OSRS), this mountain is far more than just a geological feature; it is the gateway to the Chambers of Xeric, a high-level Slayer destination, and a site steeped in dark historical significance. Whether you are a seasoned raider or an explorer venturing into the lowlands for the first time, understanding the intricacies of this mountain is vital for efficient gameplay.

Geographical Significance and Meaning

The name Quidamortem is derived from Latin, where quidam translates to "a certain someone" or "a specific thing," and mortem means "death." Together, they evoke the ominous translation of "Certain Death," a fitting title given the mountain’s history as a place of exile and the entrance to one of Gielinor's most dangerous raid dungeons.

Geographically, Mount Quidamortem dominates the Kebos Lowlands skyline. It is bordered by the Lizardman Settlement to the east, the Stranglewood to the south, and the expansive Kebos Swamp to the north. Its summit serves as the staging ground for expeditions into the ancient caverns beneath, where the power of the dark altar was once harnessed to reshape the fate of Kourend.

How to Reach Mount Quidamortem

Navigating to Mount Quidamortem can be a challenge for unprepared players due to the aggressive local fauna and the distance from traditional teleport hubs. However, several methods exist, ranging from early-game walking routes to high-efficiency end-game teleports.

Xeric’s Honor Teleport

The most efficient way to reach the mountain is by using Xeric's Talisman. After completing raids within the Chambers of Xeric, players have a chance to obtain an Ancient Tablet. Using this tablet on Xeric's Talisman unlocks the "Xeric's Honor" teleport option. This places the player directly at the entrance of the raids, right at the summit of Mount Quidamortem. For consistent raiders, this is the gold standard for transportation.

Fairy Ring Network

If you have access to the Fairy Ring network, code BLS is your best option. This ring is located just south of the mountain. Upon arriving, players must run north, navigating past a few aggressive monsters to reach the base of the mountain. From there, the ascent can be accelerated if you have already interacted with the local Mountain Guide.

Lovakengj Minecart Network

For players who have spent time gaining favor within the Lovakengj House of Kourend, the minecart network offers a reliable route. After unlocking the network and providing a minecart control scroll to Stuliette, you can travel near the area and run north. This method requires 65% Lovakengj favor and is often favored by ironmen who have yet to obtain a Xeric's Talisman.

The Long Walk from Shayzien

Early-game players or those visiting for the first time without teleports must travel on foot. The path starts at Shayzien’s Wall. You must head westward across the lowlands. It is critical to bring some form of poison protection, as the east side of the mountain is patrolled by various types of Lizardmen that can quickly drain the hitpoints of an unprepared traveler. Before reaching the mountain base, you will encounter big frogs and goblins, signaling that you are nearing the troll settlements.

The Mountain Guide and Travel Points

One of the most important NPCs on Mount Quidamortem is the Mountain Guide. He is part of a Varrock Museum expedition team and plays a crucial role in regional mobility.

Unlocking the Travel System

To make future trips easier, you must speak with the Mountain Guide at the summit. Once you have established a rapport with him, you unlock a fast-travel system that connects three key locations:

  1. The summit of Mount Quidamortem.
  2. Shayzien’s Wall.
  3. A location south of Mount Quidamortem (added in a July 2023 update).

Using this guide allows you to bypass the aggressive Lizardmen patrolling the lower slopes, saving both time and resources. In my experience, unlocking this immediately after your first arrival is the single most important task for any player planning to return for Slayer or Raids.

Combat Activities and Slayer Efficiency

Mount Quidamortem is not just a transit hub; it is a prime location for specific combat training and Slayer tasks, particularly when assigned by Konar quo Maten, the Slayer Master located on the nearby Mount Karuulm.

Hunting Mountain Trolls

The base of the mountain is home to a significant population of Mountain Trolls. What makes this spot unique compared to other troll locations (like Death Plateau) is that it is a multicombat zone. This allows players to utilize the Dwarf multicannon to its full potential.

For maximum efficiency during a Slayer task:

  • Cannon Placement: Set up your cannon in the center of the troll camp at the base of the mountain.
  • Aggression Management: The trolls are aggressive, but their levels are manageable for mid-tier players. Using Protect from Melee can make this a completely AFK (Away From Keyboard) experience while the cannon does the heavy lifting.
  • Loot: While trolls don't offer high-value drops, they provide decent seeds and noted herbs, making the task profitable when combined with the fast kill rates of the cannon.

Rock Crabs for Low-Level Training

Around the base and the nearby shores, Rock Crabs can be found. Similar to the ones in Rellekka, these are excellent for low-level players looking to train their combat stats due to their high hitpoints and low defensive stats. However, the area is less crowded than the Fremennik province, offering a more peaceful training environment.

Barbarian Fishing at the Lake

To the south of the mountain, near Historian Duffy, there are Barbarian Fishing spots. While many players default to Baxtorian Falls for this training method, the spots at Mount Quidamortem are significantly closer to a bank (located at the raid entrance summit). For players using a Fish Barrel to store their catch, the proximity to the bank at the top of the mountain makes this one of the most efficient places to train Fishing and Strength simultaneously without dropping the fish.

The Chambers of Xeric: Gielinor’s First Raid

The primary draw for the majority of players visiting Mount Quidamortem is the entrance to the Chambers of Xeric (CoX). This massive underground complex is where the disgraced king Xeric conducted his experiments and gathered his power.

Preparation at the Summit

The summit of the mountain acts as a staging ground. It features:

  • Bank Chests: Essential for gearing up before a raid.
  • The Scoreboard: Where players can track their completion times and personal bests.
  • Recruitment Boards: Used to find teams or form parties for the raid.

When preparing for CoX, players often spend significant time at the summit. The atmosphere here is one of high-level coordination. In our testing, the layout of the summit is designed for utility; everything a raider needs, from item storage to team management, is within a few tiles of the entrance.

Historical Lore: The Legacy of King Shayzien VII and Xeric

The history of Mount Quidamortem is inextricably linked to the dark past of Great Kourend. Understanding the lore enhances the experience of exploring the caverns.

The Failed Expedition of 1740

In the year 1740-36, King Shayzien VII ordered a massive expedition into the Kebos Lowlands to expand Kourend’s territory. The focus was Mount Quidamortem. However, the expedition was a catastrophic failure; the team never returned, and they were presumed dead.

Years later, journals revealed a darker truth. The expedition hadn't entirely failed in its biological goals. It was during this time that the native lizards of the region were subjected to experiments, eventually leading to the creation of the Lizardmen—the aggressive, multi-headed creatures that now plague the lowlands.

The Exile of Xeric

Xeric, a figure of immense power and cruelty, ruled Kourend for nearly a century before being forced into exile. He fled to Mount Quidamortem with his most loyal followers. Beneath the mountain, he discovered ancient caverns and an unstable altar, which he used to harness crystal power. This power allowed him to extend his lifespan and the lives of his followers, much like the residents of House Arceuus use the Dark Altar. The Chambers of Xeric are the remnants of his stronghold, filled with his creations and the treasures he hoarded during his reign.

The Tale of the Righteous Quest

Mount Quidamortem plays a pivotal role in the quest The Tale of the Righteous. This quest delves into the history of the Shayzien expedition and the truth behind the Lizardmen.

During the quest, players must visit the Quidamortem Cave. This involves navigating the mountain’s interior to find clues left behind by the lost expedition. Completing this quest is essential for players who wish to fully understand the Kourend storyline and is a requirement for the prestigious Cape of Accomplishment (Quest Point Cape).

NPCs and Personalities on the Mountain

Beyond the Mountain Guide, several other NPCs reside on the summit, each contributing to the lore or providing services:

  • Historian Duffy: A wealth of knowledge regarding the Kebos Lowlands. Speaking to him provides insight into the ruins found across the mountain.
  • Captain Rimor: Oversees the security of the expedition team.
  • Gnosi: An interesting character found near the raid entrance, adding to the mystery of the mountain.
  • Stuliette: Manages the minecart logistics for the Lovakengj house.

Why is Mount Quidamortem a High-Traffic Area?

  1. High-Level Gear: The Chambers of Xeric reward players with some of the best items in the game, including the Twisted Bow, Ancestral Robes, and Dragon Claws.
  2. Slayer Meta: Due to the multicombat trolls, it is a preferred destination for Slayer efficiency.
  3. Achievement Diary: Many tasks in the Kourend & Kebos Achievement Diary require interactions on or around the mountain.
  4. Unique Training: The combination of Barbarian Fishing and easy bank access is a niche but highly effective training method.

What is the best way to get to Mount Quidamortem for the first time?

If you are visiting for the first time, use the Fairy Ring code BLS. If you do not have Fairy Rings unlocked, you must walk from Shayzien’s Wall, heading west. Ensure you bring an Antipoison or Serpentine Helmet to deal with the Lizardmen along the way.

How do you unlock the Mount Quidamortem teleport?

The direct teleport "Xeric's Honor" is unlocked by using an Ancient Tablet on a Xeric's Talisman. The tablet is a rare drop from the Chambers of Xeric raid. Alternatively, the Mountain Guide's travel system provides a fast link from Shayzien once you have spoken to him at the summit.

Are the mountain trolls here good for Slayer?

Yes, they are among the best in the game because they are in a multicombat zone. This allows you to use a cannon to clear the task very quickly. Konar often assigns trolls in this specific location.
