Combat Achievements for Chambers of Xeric are specific tasks that require players to complete raids under certain conditions, such as defeating bosses with restrictions or achieving speed runs. These tasks are part of the broader Combat Achievements system, introduced on July 21, 2021, to test players’ combat skills across various OSRS content . For CoX, there are 29 tasks totaling 138 points, split across normal and Challenge Mode raids .

Why Focus on CoX Combat Achievements?

CoX Combat Achievements offer several benefits:

  • Rewards: Points contribute to unlocking tiered rewards, including cosmetic helms and gameplay perks.
  • Skill Improvement: Tasks encourage mastering boss mechanics and raid strategies.
  • Bragging Rights: Completing high-tier tasks showcases your PVM expertise.
  • Unique Drops: Higher points in raids increase the chance of unique loot like the Twisted Bow.

Normal vs. Challenge Mode Tasks

CoX Combat Achievements are divided between normal mode and Challenge Mode. Normal mode tasks focus on specific boss mechanics or raid completions, while Challenge Mode tasks (11 tasks, 58 points) are tougher due to enemies’ 50% increased combat stats . Challenge Mode raids follow a fixed layout, making preparation easier but execution harder.

Key CoX Combat Achievement Tasks

Below, we explore some of the most notable CoX Combat Achievement tasks, categorized by difficulty and boss. These tasks range from Elite to Grandmaster, requiring varying levels of skill and gear.

Elite Tasks: Accessible Starting Points

Elite tasks are ideal for players new to CoX Combat Achievements. They often involve simple restrictions or mechanics and don’t require top-tier gear. Examples include:

  • Dancing with Statues: Kill Vasa Nistirio without being hit by his special attack. Stay alert for his teleport and crystal activation mechanics.
  • Chambers of Xeric Veteran: Complete the raid 25 times. This is a grind but achievable with consistent runs.
  • Freeze, No One Move: Kill the Ice Demon without taking damage from ice bursts. Use safespots and time your movements carefully.

Tip: For Ironmen, tasks requiring “kill credit” (e.g., Dancing with Statues) often need solo kills, so plan accordingly .

Master Tasks: Stepping Up the Challenge

Master tasks demand better gear and familiarity with CoX mechanics. A notable example is:

  • Chambers of Xeric Master: Complete the raid 75 times . This task rewards persistence and raid proficiency.

Tip: Use a team to speed up runs, and consider scaling raids to balance difficulty and efficiency .

Grandmaster Tasks: The Ultimate Test

Grandmaster tasks, like the Challenge Mode speed runs, are reserved for elite players. For example:

  • Chambers of Xeric: CM (Solo) Speed-Chaser: Complete a solo Challenge Mode raid in under 45 minutes. This requires flawless execution and top-tier gear like the Twisted Bow .

Tip: Practice normal mode solos first to master room transitions and boss mechanics before attempting Challenge Mode.

Strategies for Success

Conquering CoX Combat Achievements requires preparation, gear, and teamwork. Here’s how to optimize your approach.

Recommended Gear and Stats

To tackle CoX tasks effectively, aim for the following stats and gear:


Skill Recommended Level Notes
Ranged 85+ Essential for bosses like Vasa and Olm.
Magic 85+ Useful for Tekton and Vespula.
Defence 90+ Survivability in Challenge Mode.
Herblore 60+ For weak overloads; 90 for max potions .

Gear Setup:

Tip: Bring a Salve Amulet (ei) for Skeletal Mystics to speed up kills .

Boss-Specific Tips

Each CoX boss has unique mechanics that tie into Combat Achievements. Here are strategies for key bosses:

  • Tekton: Use Vengeance to reflect damage and land Dragon Warhammer specials to lower his defense. Avoid his high-damage attacks in Challenge Mode .

  • Vasa Nistirio: Dodge his teleport and crystal attacks to complete tasks like Dancing with Statues. Solo runs ensure kill credit for Ironmen.
  • Vanguards: Balance damage across all three Vanguards to prevent them regenerating. Use stab weapons for the Ranged Vanguard .

  • Great Olm: In Challenge Mode, prioritize the Twisted Bow for the head phase due to its high Magic level. Use thralls to bypass the right hand’s Magic defense.

Team vs. Solo Strategies

CoX can be tackled solo or in a team, and your approach affects Combat Achievement completion.

Team Raids

Teams (up to 100 players) make raids faster and less resource-intensive. Benefits include:

  • Shared Load: Divide roles like prepper, tank, or DPS.
  • Efficiency: Clear rooms faster, ideal for tasks like Chambers of Xeric Master.
  • Learning Curve: Learn from experienced players in learner clans .

Drawback: Some tasks (e.g., kill credit tasks) may require solo runs for Ironmen.

Solo Raids

Solo raids are tougher but necessary for certain tasks. Tips include:

  • Scaling: Use Captain Rimor to scale raids if your combat level is below 115 .

  • Prep Efficiency: Master resource rooms to craft potions like Overload (+).
  • Practice: Start with normal mode to build confidence before Challenge Mode.

Rewards and Motivation

Completing CoX Combat Achievements unlocks significant rewards, making the grind worthwhile.

Reward Tiers

Combat Achievement points unlock rewards at Ghommal or Laidee Gnonock at the Warriors’ Guild . CoX-specific rewards include:

  • Elite Tier: Access to faster points for early tasks.
  • Master Tier: Progress toward the Zuk Slayer Helm.
  • Grandmaster Tier: Prestige and potential for unique raid drops.

Increasing Unique Drop Chances

Higher raid points, earned through Combat Achievements, boost the quantity of common loot and the chance of uniques like the Twisted Bow or Dragon Claws . For example, mega-scaled raids can yield up to a 45% chance of a purple drop .

By mastering the Chambers of Xeric Combat Achievements, you’ll not only enhance your OSRS experience but also cement your status as a skilled PVMer. Start with Elite tasks, build your skills, and work toward the prestigious Grandmaster tier. Happy raiding!
