OSRS Infernal Cape: Inferno Waves, Gear and Prep

To earn the OSRS infernal cape you must survive all 69 waves of the Inferno in Mor Ul Rek and defeat TzKal-Zuk on the final wave, after giving up a fire cape once to get in. It is a solo fight with no restocking between waves, and dying sends you back to wave 1 with your items intact. The wiki counted 179,363 accounts with the cape as of 1 November 2026, so plenty of players manage it, but almost nobody does it on the first try. Below are the wave structure, how the Zuk fight works, the suggested stats and gear, and what you get beyond the cape.

We checked this against the OSRS Wiki pages for the Inferno, its strategy guide, the infernal cape and Combat Achievements, plus the Ironman Mode page, in November 2026.

What the Infernal Cape Gives You

The infernal cape is the strongest melee cape in terms of overall bonuses. It gives +4 stab, slash and crush attack, +1 magic and ranged attack, +12 to every defence, +8 melee strength and +2 prayer. That beats its predecessor, the fire cape, on melee attack and strength and slightly on defence. It is not the best in every column, though: the Ardougne cloaks 3 and 4 have higher stab attack and prayer, and the mythical cape has more crush attack.

The cape is untradeable and cannot be alchemized. You can combine it with a max cape to create the infernal max cape. If you die a PvP death at level 20 Wilderness or below with it unprotected, it stays with you in a broken state that costs 225,000 coins to repair with Perdu. Deeper in the Wilderness it turns to coins unless you have locked it with a Trouver parchment and 500,000 coins, in which case it becomes mangled and costs another 500,000 to fix.

Beyond stats, the cape is a status item. The Inferno was billed as the greatest solo PvM challenge when it launched on 1 June 2017, and the cape still signals that a player can handle long, high-pressure fights.

Getting Into the Inferno

The Inferno is a members-only minigame inside Mor Ul Rek. Access costs a fire cape, handed to TzHaar-Ket-Keh once; after that you can enter as often as you like. Beyond the fire cape there are no formal requirements, which is why the strategy guide stresses preparation instead.

The rules inside are strict. Only you can enter, you cannot restock between waves, purple sweets do not work, and you cannot teleport out. You can pause the run by trying to log out between waves, though since March 2018 you can no longer log out at the very start of a wave. If you die, you return to the entrance, keep all your items, and receive Tokkul based on the wave you reached. There is no fee for dying.

The Inferno is a safe death for a solo Hardcore Ironman, so failing will not cost Hardcore status. It is not safe for Hardcore Group Ironmen, where a death costs one of the group's shared lives. Our Ironman guide lists the other activities where that difference matters.

How the 69 Waves Are Built

Each wave shows which monsters will spawn, and the waves follow a fixed pattern. Waves 1 to 17 introduce nibblers, bats, blobs and the melee monster; rangers join from wave 18, magers from wave 35, and from wave 50 to 66 both rangers and magers appear together. Wave 67 is a single JalTok-Jad, wave 68 is three Jads at once that attack three ticks apart, and wave 69 is TzKal-Zuk.

Knowing what each monster does is half the battle. Jal-Nibs, the nibblers, attack the three pillars you use for safespotting, and each pillar has 255 hitpoints. Bats drain run energy on every hit. Blobs read your protection prayer and attack with the opposite style, then split into three smaller blobs when they die. The melee monster burrows and reappears next to you if it cannot reach you for 30 seconds. Rangers and magers can both melee adjacent tiles, and the mager can revive slain monsters at half health, once each.

Any pillars still standing collapse when wave 66 ends, dealing half your current hitpoints if you stand next to one. Before the triple Jad wave, make sure your prayer and supplies are in good shape, because the three Jads each summon three healers at half health on wave 68, while the single Jad on wave 67 summons five.

The TzKal-Zuk Fight

On wave 69, TzKal-Zuk breaks out of the northern wall. He has 1,200 hitpoints and cannot be reached with melee. His attacks can hit up to 148, enough to kill you outright, so you must stand behind the Ancestral Glyph, a shield that floats back and forth in the lava between you and him. His attacks cannot be tick eaten either.

Other monsters keep spawning. A ranger and a mager appear behind you on a repeating timer of three and a half minutes and attack the shield until you hit them; if you ignore them too long, the shield breaks and leaves you exposed. When Zuk drops below 480 hitpoints, a JalTok-Jad spawns behind you as well, and the set timer gets a one-time extra 1 minute 45 seconds so you can deal with it.

The final phase starts under 240 hitpoints. Four Jal-MejJak healers spawn and heal Zuk until attacked, and when you hit them they throw lava at the arena. Zuk's attacks also speed up sharply at this point. Many attempts end here, so practice the shield timing and the four consistent safe positions the wiki describes for the earlier part of the fight.

Suggested Stats, Gear and Supplies

The wiki's strategy guide suggests 90+ Ranged, 90+ Defence, 80+ Prayer, 90+ Hitpoints and 94+ Magic for Ice Barrage, and it strongly recommends the Rigour and Augury prayers. It is just as clear that player skill and experience matter more than anything else, and it tells readers to expect to fail several times.

For gear, it names the twisted bow as the most influential investment, with the Bow of Faerdhinen as the more affordable next best option. Interestingly, it says expensive armour such as the elysian spirit shield, Masori and Virtus only performs modestly better than cheaper crystal armour, a crystal shield and Ahrim's robes, and that crystal armour beats Armadyl or dragonhide here thanks to its ranged defence and prayer bonus. The toxic blowpipe appears in every suggested loadout.

The strategy page also documents a newer tank-style option. Pairing the confliction gauntlets with the fast Eye of Ayak gives reasonable damage while you wear heavy melee armour, which adds a safety net if you get hit off-prayer. For that setup the guide recommends aiming for about +60 Magic attack bonus so damage on blobs stays consistent, and suggests Tumeken's shadow for magers, Jads and Zuk to save inventory space. There is no single correct loadout; the guide's own advice is that the best setup is the one that works for you, adjusted as you learn.

Supplies centre on Saradomin brews and super restores, with the quantity depending on how much you prayer flick, plus two or three prayer regeneration potions and a stamina potion. A rune pouch with soul, blood and death runes covers Ice Barrage and Blood Barrage. The Falador shield 4 is an optional extra for its two daily prayer restores, one of several diary perks covered in our Achievement Diary guide. These supplies are not cheap across repeated attempts, so a steady income from our money making guide helps.

Rewards Beyond the Cape

Each run pays Tokkul based on how far you got, up to 16,440 for a full clear, doubled if you have the elite Karamja diary. Killing Zuk also has a 1 in 100 chance of the Jal-Nib-Rek pet, improved to 1 in 75 on a Slayer task. You can give spare infernal capes to TzHaar-Ket-Keh for another 1 in 100 roll at the pet, although once you own the pet he will no longer accept capes for that purpose.

After your first kill, Zuk can be chosen as a TzHaar Slayer task, which covers every monster inside. Combat Achievements add more reasons to return: the Master tier raises TzTok-Jad and TzKal-Zuk tasks to two kills, Grandmaster raises them to three, and the Grandmaster Tzkal slayer helmet, once imbued, gives on-task damage bonuses in the Inferno. Our Combat Achievements guide covers those tiers.

If the Inferno Is Not for You Yet

Plenty of players are not ready for 69 waves and want a different starting point for their account. Our Old School RuneScape page lists accounts, and the listings change every day.

Be aware of the rules. Jagex's Rules of RuneScape do not allow accounts to be transferred, lent, shared or sold, and the wiki notes that since March 2021 the account-trading rule explicitly covers buying and selling services such as having someone else complete the Inferno for an infernal cape on your account. The cape is meant to be earned in the fight itself.
