The short version

30-second read
  • Ice Barrage the nibblers at every wave start. That needs 94+ Magic, and losing a pillar early makes waves 40 and up much harder.
  • Crystal armour beats Armadyl and d'hide here. Its ranged defence and prayer bonus win even without a bow of Faerdhinen, and a twisted bow is the biggest upgrade.
  • Kill Jal-Zek magers as soon as they appear. They arrive from wave 35 and revive dead monsters, so leaving them last keeps the wave going.
  • Failed runs cost supplies, not gear. It is a safe minigame, and logging out between waves pauses the run whenever a break is needed.
01

Overview

The Inferno is 69 waves in Mor Ul Rek: waves 1 to 66 are regular monsters, wave 67 is one JalTok-Jad, wave 68 is three Jads at once, and wave 69 is TzKal-Zuk. The strategy that gets most players through is simple to say. Freeze or kill the nibblers at the start of every wave so your three pillars survive, use those pillars so only one monster can hit you at a time, flick prayers when two have to, and at Zuk stay behind the moving shield above everything else.

Entry costs one fire cape, handed to TzHaar-Ket-Keh the first time you go in. Beating Zuk gives the infernal cape, the best melee cape in the game. A full run usually takes over an hour, there is no restocking between waves, and a death sends you back to wave 1.

The sections below go through what each Inferno monster does, the wave breakdown, why pillar management is the whole mid-game, supplies for a run you cannot restock, and the Zuk fight hitpoint by hitpoint. If you only want the cape and not the practice runs, an infernal cape service is the other route; the rest of this page is for doing it yourself.

Requirements and Access

The Inferno has no quest or skill requirement, but it does have an entry fee. You need a fire cape to get past the guard into inner Mor Ul Rek, and the first time you enter the Inferno you give a fire cape to TzHaar-Ket-Keh. After that you can enter as often as you like.

Table 2What you actually need4 rows
RequirementDetail
Fire capeRequired. Shown to enter inner Mor Ul Rek and given to TzHaar-Ket-Keh for your first entry.
Prayer switchingEvery monster in waves 1 to 68 can be fully blocked by the right protection prayer, so flicking is your main defence for over an hour.
No restockingEverything you bring is everything you get for 69 waves. You can pause between waves by logging out, but you cannot bank.
High Ranged, Defence and HitpointsRanged carries the run, and low Hitpoints turns one missed prayer into a death.

The Inferno is a safe minigame, so failed attempts cost supplies and time rather than gear. Treat your first several runs as paid practice. That is the normal path.

03

Getting There

The Inferno entrance is in the inner area of Mor Ul Rek, the TzHaar city under the Karamja volcano that also holds the Fight Caves.

  1. 1

    Reach Mor Ul Rek with fairy ring BLP or the TzHaar Fight Pit minigame teleport.

  2. 2

    Show your fire cape to the TzHaar-Ket guarding the inner city.

  3. 3

    Give TzHaar-Ket-Keh a fire cape the first time, then enter the Inferno.

Because runs are long, set everything up before you enter: gear layout, prayer keybinds and tile markers for the Zuk safespots.

05

Gear Setups: Budget, Mid and Best in Slot

Every first-cape setup on the wiki pairs a toxic blowpipe with a long-range weapon and an Ancient Magicks switch for nibblers. A twisted bow is the single most influential upgrade. Crystal armour beats Armadyl and d'hide here because of its higher ranged defence and prayer bonus, even without a bow of Faerdhinen.

Dart tier matters over 69 waves. Cheap darts turn survivable waves into long ones, and long waves burn prayer. Expensive armour only performs modestly better than crystal or Ahrim's, so put money into the weapon first.

06

Inventory and Supplies

A run has no restock, so supply planning is part of the strategy. A common way to lose an Inferno run is arriving at Zuk with nothing left.

  • Saradomin brews and super restores as the backbone of your inventory.
  • Extra darts and bolts or arrows. Running dry in the 60s ends the run.
  • Ranging potions or divine ranging potions for the Jad waves and Zuk.
  • Runes for Ice Barrage and Blood Barrage. Blood Barrage on a wave you have under control heals you without spending brews.
  • A stamina potion for the Zuk fight, where you move with the shield the whole time.

Budget your supplies against waves, not against how you feel. If you have used half your brews before wave 40, change how you use the pillars before pushing on.

07

Inferno Waves 1 to 69

The wave list follows a pattern. A wave of six nibblers comes right before each new monster type, and the second of a type only shows up once the doubles of every earlier type have cycled through. Every wave up to 66 also spawns three or six nibblers that go for your pillars.

Table 5When each Inferno monster first appears9 rows
WavesWhat changes
1 to 3Nibblers and bats (Jal-MejRah). Wave 3 is six nibblers.
4 to 8Blobs (Jal-Ak) join from wave 4. Wave 8 is six nibblers.
9 to 17Meleers (Jal-ImKot) join from wave 9. Wave 17 is six nibblers.
18 to 34Rangers (Jal-Xil) join from wave 18. Wave 33 has two rangers, wave 34 is six nibblers.
35 to 49Magers (Jal-Zek) join from wave 35 and appear in every wave until 66.
50 to 66Waves 50 to 65 have a mager and a ranger plus the rest of the rotation (two rangers on 65). Wave 66 is two magers and no ranger.
67One JalTok-Jad, which calls five healers at half health. Remaining pillars collapse at the start of this wave.
68Three JalTok-Jads, each calling three healers at half health.
69TzKal-Zuk.

The three pillars have 255 hitpoints each. Any still standing when the last monster of wave 66 dies collapse, and standing within one tile of a collapsing pillar costs half your current hitpoints, so step away before you finish wave 66. The full wave list is on the OSRS Wiki Inferno page.

Mechanics You Have to Respect

The Inferno's difficulty comes from monsters that interact with each other. Nibblers chew your pillars, magers revive dead monsters, blobs read your prayer, and meleers dig to you if you leave them stuck too long.

Table 6Attacks and correct responses9 rows
MechanicWhat it doesCorrect response
Jal-Nib (nibblers)Spawn in the middle and attack a random pillar. With no pillars left, they chase you.Ice Barrage them at the start of every wave. Losing a pillar early makes later waves much harder.
Jal-MejRah (bat)Short-range ranged attacks (max 19). Hits drain run energy, and when you are not praying ranged they can lower your combat stats by 1.Low priority. Trap it behind a pillar, pray against it when you can, and kill it after the dangerous monsters.
Jal-Ak (blob)Checks your prayer and attacks with whichever of magic or ranged you are not protecting against. Splits into three small blobs, one per style, when it dies.Prayer-flick it from behind a pillar, and kill it where you have room for the three splits.
Jal-ImKot (meleer)Melee only, max 49. If it cannot attack you for a while, it burrows and pops up next to you.Safespot it, but expect the dig. Let it surface when nothing else is attacking you, then kill it.
Jal-Xil (ranger)Ranged attacks up to 46, plus melee on any adjacent tile, diagonals included.Protect from Missiles, and kill it before stacking more threats.
Jal-Zek (mager)Magic up to 70, plus melee when adjacent. Revives monsters killed in the current wave at half health, each one once.Kill it first when you can, or the wave keeps coming back. A twisted bow is very effective against it.
JalTok-Jad (waves 67 to 69)Same animations as TzTok-Jad with a 113 max hit. Wave 68 has three of them, attacking three ticks apart.Pray off the animation: rearing up and breathing fire is magic, the short rear and ground slam is ranged. Stay out of melee range.
TzKal-ZukFireball up to 148 that cannot be prayed against or tick-eaten.Stay behind the Ancestral Glyph, the moving shield, at all times.
Jal-MejJak (Zuk's healers)Four appear at 240 hitpoints and heal Zuk until attacked, then throw lava that hits 5 to 10 in an area.Tag each one with a fast weapon so it stops healing, and keep your health above 25.

Pillar management is the mid-game skill. Every wave, ask which pillar you are protecting, which monster is threatening it, and which monsters you can trap behind it.

09

Zuk Strategy: Wave 69 by Hitpoints

Zuk has 1,200 hitpoints, cannot be reached with melee, and hits up to 148. The Ancestral Glyph moves back and forth across the arena edge, and its safe area is 5 tiles wide and 3 deep. The shield itself has 600 hitpoints, so anything left attacking it will eventually break it.

  1. 1

    From the start:

    move with the shield and use the four marked safespot tiles, which line up with Zuk's attack cycle before he enrages. Do not attack from the drag tiles that have no line of sight, or you get pulled out of cover.

  2. 2

    After the shield's first full rotation, a Jal-Xil and Jal-Zek spawn behind you and attack the shield. Tag them, pray magic, and kill them. A new pair comes roughly every 3 minutes 30 seconds.

  3. 3

    At 600 hitpoints the pair timer pauses and gains 1 minute 45 seconds.

    Kill the mager and keep damaging Zuk.

  4. 4

    At 480 hitpoints a JalTok-Jad spawns behind you and attacks the shield.

    Tag it straight away and kill it while still moving with the shield.

  5. 5

    After Jad, stop around 300 hitpoints until the next pair is dead.

    Dropping him below 240 spawns the healers, and you do not want both at once.

  6. 6

    At 240 hitpoints four Jal-MejJak spawn and Zuk's attack speed goes from 10 ticks to 7, which breaks the middle safespots. Stay with the shield and tag the healers with your blowpipe.

  7. 7

    With the healers dead, use your remaining brews and restores and finish him.

    Anything still alive dies with Zuk.

The wiki's advice is to stay level with or slightly ahead of the shield, because its true tile can be ahead of where it looks. No extra attack is worth a Zuk hit.

10

Run Plan: Waves 1 to 68

Split the run into phases with different goals: survive cheaply early, protect pillars in the middle, and arrive at the Jad waves with supplies intact.

  1. 1

    Early waves:

    barrage the nibblers, clear efficiently and spend as little as possible.

  2. 2

    Protect the pillars.

    A destroyed pillar early makes waves 40 and up much harder.

  3. 3

    Kill Jal-Zek magers early once they appear on wave 35, so nothing revives behind you.

  4. 4

    Use pillars so you face one style at a time, and flick between two when you must.

    A ranger and mager hitting you together is how good runs die.

  5. 5

    Pause between waves by logging out if you need a break.

    The next wave will not start until you log back in.

  6. 6

    Step away from the pillars before the last kill of wave 66 so the collapse does not take half your health.

  7. 7

    On wave 67, fight the single Jad from range and tag all five healers.

  8. 8

    On wave 68, focus on praying, not attacking.

    The triple Jads guide covers the three-tick rhythm.

  9. 9

    Before Zuk, restore health and prayer as fully as your remaining supplies allow.

If you reach Zuk without supplies, that information is still useful. Note which wave drained you and fix that wave next run.

11

Solo Versus Team

The Inferno is strictly solo. There is no team mode and no other player can enter your instance.

The infernal cape is untradeable, so it cannot be bought from the Grand Exchange.

The Fortis Colosseum is the other big solo wave challenge, with twelve waves and Dizana's quiver at the end.

12

Common Mistakes and What Actually Kills You

Late deaths usually trace back to an earlier wave: a pillar lost to nibblers, or brews spent on damage you could have avoided.

  • Letting nibblers destroy pillars in the early waves.
  • Killing magers last, so the wave keeps reviving.
  • Leaving a meleer safespotted while something else is attacking you, so it digs up at the worst moment.
  • Fighting two attack styles at once instead of using line of sight.
  • Burning brews on damage you could have avoided by repositioning.
  • Standing next to a pillar when wave 66 ends.
  • Attacking on wave 68 when you should be praying.
  • Losing track of Zuk's shield while focused on damage.
  • Taking Zuk below 240 while a ranger and mager pair is still alive.
13

Drops Worth Knowing

The Inferno is a prestige unlock, not a money method. Its value is the cape and what the cape signals.

Table 7Notable drops3 rows
DropWhy it matters
Infernal capeGuaranteed on a completion. The best melee cape in the game and the reason people run the Inferno.
Jal-Nib-RekThe pet: 1/100 on a completion, 1/75 on a Slayer task. TzHaar-Ket-Keh also takes spare infernal capes for another 1/100 roll.
TokkulUp to 16,440 for a completion, doubled with the Karamja elite diary. Failed runs pay less, based on the wave you reached.
14

Combat Achievements

TzKal-Zuk has 12 Combat Achievement tasks, mostly grandmaster. Examples: Nibblers, Begone! (master) means no pillar falls before wave 67, Budget Setup means killing Zuk without equipping a twisted bow, Playing with Jads means finishing wave 68 within 30 seconds of the first Jad dying, and Inferno Speed-Runner is a completion under 65 minutes.

Get one clean cape first. Chasing a restricted task on an early attempt just makes an already long run longer.

15

Ironman Notes

For an ironman the infernal cape is a big unlock because it is untradeable and best in slot for melee.

The gating factor is supplies: Saradomin brews and super restores in the quantities an Inferno run needs are a real Herblore and Farming project. Stockpile before attempting, and expect several attempts.

Darts are also a bottleneck on an iron. Plan your dart supply as carefully as your food, because running out of ammunition wastes the whole run.

16

FAQ

Do I need a fire cape before the Inferno?

Yes. You need one to enter inner Mor Ul Rek, and you give one to TzHaar-Ket-Keh the first time you enter the Inferno. It is a one-time fee.

Do I lose my gear if I die in the Inferno?

No. It is a safe minigame, so failed attempts cost supplies and time only, and you restart from wave 1.

How many waves does the Inferno have?

69. Waves 1 to 66 are regular monsters, wave 67 is one JalTok-Jad, wave 68 is three, and wave 69 is TzKal-Zuk.

Which monster should I kill first?

Usually the Jal-Zek mager, because it revives monsters killed in the same wave. If another monster is hitting you and you cannot hide from it, kill that one first. Bats are low priority: they drain run energy, not prayer.

How do I survive the triple Jads?

They are wave 68. The three Jads attack three ticks apart on a nine-tick cycle, so you read one animation every three ticks. Keep prayer high, focus on praying rather than attacking, and remember each Jad only calls three healers.

What is the best Zuk strategy?

Stay with the shield, kill each ranger and mager pair before it breaks the shield, tag the Jad at 480, hold Zuk around 300 until the next pair is dead, then push through 240 and tag the four healers.

17 · Bottom line

Bottom Line

The Inferno rewards preparation. Barrage the nibblers, protect your pillars, kill magers early, never take two styles at once without flicking, and arrive at Zuk with supplies left.

You keep your items on death, so the real cost of learning is time and consumables. Treat early runs as data: find the wave that drains you and fix that one thing.
