Old School RuneScape's first raid remains one of its most misunderstood pieces of high-end PvM. Normal Chambers of Xeric are the entry point for teams learning Olm, but Challenge Mode is a different animal: a fixed linear layout, +50% combat stats on every pre-Olm enemy, and two exclusive cosmetic rewards that still move the market. This guide compares normal and Challenge Mode, breaks down spec priorities, and explains how to scope a service quote so you know exactly what you're paying for.
What Challenge Mode Actually Changes
Challenge Mode toggles a checkbox at raid creation. Instead of a random layout chosen from small, medium, or large options, CM forces every floor to spawn in the same order. All enemies except the Great Olm gain 50% to their combat stats, including health, which means rooms that were routine in normal mode can suddenly stack chip damage. The fixed layout is a double-edged sword: you can plan your inventory perfectly, but there is no scouting to skip bad rooms.
- Top level: Tekton, Jewelled Crabs, Scavenger beasts, Ice demon, Lizardman shamans, resource room.
- Middle level: Vanguards, Thieving room, Scavenger beasts, Vespula, resource room, Tightrope room.
- Lower level: Guardians, Vasa Nistirio, Scavenger beasts, Skeletal mystics, Muttadiles, resource room.
Hourly profit guides reinforce the gap: normal mode is listed at 7,892,231 coins per hour, while Challenge Mode climbs to 9,464,425. The extra profit comes from the exclusive CM rewards, not just faster clears.
Requirements and Recommended Stats
- Access to Great Kourend (quest requirements vary; verify on wiki)
- Normal mode: 80+ Attack, Strength, Defence, Ranged, Magic, 70+ Prayer, 55+ Herblore/Farming, 30+ Construction.
- Challenge Mode: 90+ in all combat styles, 77+ Prayer for Piety/Rigour/Augury, 78+ Herblore for strong potions, 75+ Mining/Woodcutting/Thieving for shortcuts and rooms.
- A party member with 55+ Herblore, 78+ Herblore, 30+ Construction, 84+ Ranged and 80+ Magic recommended for CM according to the money making guide.
Those numbers are a floor, not a ceiling. A 90+ combat account can still die repeatedly in CM if prayer switches and safespots are sloppy. The fixed layout lets you choose gear specifically for Tekton, Vasa, Guardians, and Olm, but only if you already know what those rooms demand.
Point Scaling and Why It Matters for Drops
Every raid completion grants points. Your share of common loot scales to 131,071 points, but uniques use your total points before that cap. Damage dealt is the primary source, followed by utility actions: building storage units gives 100 points per tier, clearing a shortcut gives its level requirement times 5 (for example, an 86 Mining shortcut is worth 430 points), and other rooms add smaller amounts. Death is the big penalty: a player loses 40% of their current personal points, and if they die with less than 5% of the team total, the team total is reduced by 5% instead. Leaving early does not lower the multiplier, but unique rolls for leavers are discarded to prevent megascale abuse.
This point system is exactly why Challenge Mode runs are often priced differently from normal carries. A CM run with no deaths yields a much higher expected unique value than a run where the learner dies twice.
Room-by-Room Differences in Challenge Mode
The fixed CM layout removes scouting but increases every non-Olm encounter. Here is a quick reference for the two modes:
| Factor | Normal Mode | Challenge Mode |
|---|---|---|
| Layout | Random small/medium/large, scoutable | Fixed linear: all rooms spawn in set order |
| Enemy stats | Baseline | +50% combat stats (except Great Olm health) |
| Great Olm health | Baseline | Same as normal |
| Unique rewards | Standard unique table | Standard plus twisted ancestral kit / metamorphic dust |
| Hourly profit (guide) | 7,892,231 | 9,464,425 |
| Recommended stats | 80+ combats | 90+ combats |
The Muttadile room is one of the biggest early filters in CM. The safespot shown above is heavily used, but the +50% stats mean one missed tick can cost a full inventory of food.
Great Olm: The Real Test
Great Olm is the constant between both modes. Its health does not change in Challenge Mode, but the fight is the filter because you arrive with fewer supplies and less room for error. Olm attacks with magic and ranged orbs; prayer reduces damage by roughly 75-80%, and it has a 20% chance to swap styles after attacking. Spheres come in red, green, and purple varieties and must be blocked or they deal about half of your health. The head can face left, right, or middle, and safespotting revolves around forcing head turns by standing in quadrants outside its visual range. Solo raiders use 3:0 mage hand and 4:1 melee hand cycles; teams coordinate hand damage to control head turns.
From the strategy page, the safespot picture shows that spots 1 and 8 force the head left, 4 and 5 force it right, and 2, 7, 3, and 6 force middle depending on the current facing. Those are the building blocks for avoiding damage while dealing hand damage.
Rewards: Twisted Kits, Metamorphic Dust, and Dark Journal
The Ancient Chest rolls a unique or two standard loot rolls. Challenge Mode adds two chase items: metamorphic dust and the twisted ancestral colour kit, both rolled independently if the team completes a CM raid. The chest beam changes colour: white for standard, purple for unique, turquoise for metamorphic dust, green for twisted ancestral kit, and alternating when multiple drop. The dark journal is a guaranteed first-time drop from the chest. Repeated CM completions also unlock Xerician cape accolades: Xeric's guard at 100, warrior at 500, sentinel at 1000, general at 1500, champion at 2000.
Because metamorphic dust and twisted kits only come from CM, they are the main reason players pay for carries. The beam gif above is exactly what you want to see after an hour of focused play.
Gear Rungs and Special Attack Priorities
Gear decisions are driven by room-specific weaknesses. Tekton is weak to crush, Vasa's crystals require stab, Guardians need a pickaxe, and Ice Demon benefits from burning claws. At Olm, defence-reducing special attacks are the highest priority: Bandos godsword, dragon warhammer, or elder maul. The BGS drains more total defence than the elder maul after two successful hits, so it is the default in larger teams, while DWH is cheaper and still strong. Scythe of Vitur is best-in-slot for melee hand and Tekton, but dragon hunter lance or hasta work on a budget.
- Budget: Abyssal tentacle, Zamorakian hasta, toxic trident, blowpipe, dragon warhammer.
- Standard: Bow of Faerdhinen, Osmumten's fang, Dragon hunter lance, Bandos godsword.
- High-end: Scythe of Vitur, Tumeken's shadow, Twisted bow, Torva, Amulet of rancour, Zaryte crossbow.
Special attack order matters. At Olm, you want to land your defence reduction early, then switch to damage specs like dragon claws or voidwaker. In CM, the longer Tekton fight makes crush-accuracy gear more valuable than in normal mode.
Common Mistakes and Death Costs
The most expensive mistakes in Challenge Mode are almost always planning errors, not mechanical misclicks.
- Forgetting to prepot for specific first rooms because normal habits rely on scouting.
- Underestimating +50% stats on Vanguards, Muttadiles, or Tekton, leading to early deaths.
- Not bringing a pickaxe or axe for Guardians/Ice Demon, losing easy points.
- Mismanaging run energy on Tightrope without stamina or phoenix necklaces.
- Dying at Olm and losing 40% personal points.
- Leaving a raid early, which can discard your unique roll.
Each death in CM also adds minutes to the run, which compounds over a farming session. A team that averages one death per raid is losing far more than the supply cost.
Learning vs Boosting for CM Kits
Learning Challenge Mode is a multi-step process. Start with normal solos or duos until you can kill Olm without dying more than once. Then switch to CM with a friend or small team, using the fixed layout to refine your inventory. If your goal is one twisted kit or metamorphic dust, the learning curve may be dozens of hours. A service quote for CM completions or a teaching duo can compress that time, and buyers should be honest about whether they want the items or the experience.
Many high-end players learn CM because the cape accolades are prestigious, but the items themselves can be obtained through a carry. There is no shame in scoping a quote for a single twisted kit if you would rather spend your next ten hours elsewhere.
How to Scope a CoX/CM Service Quote
Quote scoping depends on five variables: mode (normal or CM), team size, goal (single completion, kit/dust farming, cape accolades), account stats and gear, and whether you want a full carry or a learning run. Use the service calculator to estimate but be ready to provide your combat levels, prayer unlocks, and gear tab. If you are unsure whether your account meets CM requirements, ask the provider to verify against the wiki stat list.
- Normal or Challenge Mode?
- Solo, duo, or small team?
- How many completions or which specific reward?
- What are your combat stats and unlocked prayers?
- Do you want a full carry, a duo teaching run, or just a gear review?
Practical Next Step
Start by running a normal raid to see your current point share and death count. Then check the CM recommended stats and pick one gap to close. If the gap is time, a quote can help you decide between buying a kit and learning the mode. Verify any fact you are unsure about on the official wiki pages linked below.

What is the difference between CoX normal and Challenge Mode?
Challenge Mode uses a fixed linear layout with every room, while normal mode is random and scoutable. In CM, all enemies except Great Olm have +50% combat stats. CM also adds exclusive drops like twisted ancestral kits and metamorphic dust, and has a higher hourly profit guide value.
How do I unlock Challenge Mode in OSRS?
Challenge Mode is unlocked when forming a raid party. The leader simply selects the 'Challenge Mode' checkbox before starting the Chambers of Xeric raid. No additional quest or unlock is required, but recommended stats are 90+ in combat styles and 77+ Prayer.
What rewards are exclusive to Challenge Mode?
Only Challenge Mode rolls the twisted ancestral colour kit and metamorphic dust. These are independent rolls on the Ancient Chest. The chest beam turns green for a twisted kit and turquoise for metamorphic dust. CM also counts toward Xerician cape accolades.
Is Challenge Mode worth it for money making?
The wiki money making guide lists CM at about 9.46 million coins per hour, compared to 7.89 million for normal mode. The extra profit comes from exclusive kit and dust rolls, but CM requires higher stats and better execution to avoid deaths that reduce points.
What stats and gear do I need for CoX Challenge Mode?
You need 90+ Attack, Strength, Defence, Ranged, and Magic, 77+ Prayer for Piety/Rigour/Augury, 78+ Herblore, and 75+ Mining/Woodcutting/Thieving. Gear should include a crush weapon for Tekton, a stab weapon for Vasa, and defence-reducing specs like BGS or DWH for Olm.
How does death affect my CoX points and drops?
When you die in CoX, you lose 40% of your current personal points. If you die with less than 5% of the team total, the team total is reduced by 5% instead. This directly lowers your unique drop chance, making deaths very costly in Challenge Mode.
Can I buy a CoX Challenge Mode boost for twisted kits?
Yes, many services offer CM completions or full carries for twisted ancestral kits and metamorphic dust. When scoping a quote, specify team size, number of completions, and whether you want a learning run or a full carry. Always verify the provider follows Jagex rules.
