TzKal-Zuk Best in Slot Gear & Strategy Guide

TzKal-Zuk lives at the end of the Inferno, a solo minigame inside Mor Ul Rek in the TzHaar city. To unlock access you give TzHaar-Ket-Keh a fire cape — a one-time fee, after which you can enter as often as you like. There are otherwise no requirements to attempt the Inferno, but it is widely regarded as one of the hardest solo challenges in the game.

You reach Zuk only by surviving all 69 increasingly difficult waves; if you die, you start again from wave one. The wiki suggests very high combat stats before attempting it: around 90+ Ranged, 90+ Defence, 80+ Prayer, 90+ Hitpoints, and 94+ Magic for Ice Barrage. More important than any single stat, though, is experience — be prepared to fail and learn.

Zuk can also be killed in place of a TzHaar Slayer task after unlocking the Hot Stuff perk for 100 Slayer reward points, but only once you have already defeated him at least once off-task.

The Inferno is a ranged-and-magic encounter — Zuk floats in lava away from your platform and cannot be hit with melee, so your whole loadout is built around ranged DPS with a magic switch for spawns. The wiki calls the twisted bow the single most influential gear investment for the Inferno; a bow of Faerdhinen is the next-best and far more affordable, performing well on both Zuk and the magers. Crystal armour is favoured over Armadyl or dragonhide here for its higher ranged defence and prayer bonus.

For the rest, the wiki notes that expensive armour only performs modestly better than cheaper counterparts — player skill matters far more. Rigour and Augury are strongly recommended prayers. Rather than memorising an exact item list, plug your stats and budget into our Boss Gear Finder above to build a loadout you can actually afford. For style-by-style upgrade paths, see our ranged gear guide and magic gear guide.

Because you cannot restock mid-run, you arrive at Zuk with whatever is left. A typical late-game inventory is built almost entirely around healing and prayer: a large stack of Saradomin brews and super restores (the exact split depends on how much you prayer-flick), plus Bastion potions, prayer regeneration potions, and a stamina potion. The stamina potion specifically comes into play at Zuk, where you constantly move with the shield.

You also carry a rune pouch for Ice Barrage and Blood Barrage — soul, blood and death runes (plus water runes if you are not using a Kodai wand). Ice Barrage freezes and clears the nibblers efficiently through the early waves, while Blood Barrage on a spawn can top you up. TzKal-Zuk also has a 40% elemental weakness to water spells, so your Ice Barrage lands noticeably harder against him. Do not be sparing with supplies on Zuk; it is the final wave, so spend everything you have left.

The shield (Ancestral Glyph). When the fight starts, the glyph that once sealed Zuk now floats between you and him and slowly drifts back and forth. Staying behind it is mandatory. Zuk is extremely accurate, his attack has a max hit of 148, and that hit cannot be prayed against or tick-eaten — getting caught out of cover can kill you outright even when overhealed. Because the shield's animation is not perfectly accurate to its true position, the wiki advises staying in the middle or slightly in front of it rather than tucked behind. Always move with the shield; never take an extra hit on Zuk if it risks stepping into the open.

Zuk's projectile. His attack is a hybrid roll that averages your Ranged and Magic defence against the average of his Ranged and Magic accuracy. While you are behind the shield it is blocked indefinitely, so positioning — not prayer — is what keeps you alive.

Magers and rangers. Periodically a Jal-Zek (mager) and Jal-Xil (ranger) spawn and first attack the shield, which only has 600 Hitpoints and will be destroyed if it takes too much. Tag them to pull aggression onto yourself, Protect from Magic against the pair, and kill the ranger when you are on the east side while damaging Zuk from the west. The ranger can hit hard, so keep your health above 50.

Jad at 480 HP. When Zuk drops to 480 Hitpoints a JalTok-Jad spawns. It behaves like the Fight Cave Jad but stronger, switching between magic and ranged attacks that you must pre-pray by reading its animation. Tag it immediately and kill it, then continue on Zuk — but do not push him below 240 (around 300 is a safe stopping point) so you are not fighting healers and a fresh spawn at once.

Enrage and healers at 240 HP. At 240 Hitpoints Zuk enrages, attacking three ticks faster (speed 10 down to 7) and summoning four Jal-MejJak healers on the lava. Each heals Zuk for roughly 15–25 HP every few ticks, so tag them quickly to stop the healing; once struck they instead launch AoE spark blasts dealing 5–10 damage in a small area. Swap to the blowpipe for its speed to tag them, keep your health above 25, then return to Zuk. Any minions still alive when Zuk dies perish with him.

The fight is a sequence of HP thresholds. Phase 1 (1200→600): stay behind the shield, deal what damage you safely can, and clear each mager/ranger pair as it spawns — Protect from Magic, kill the ranger from the east, chip Zuk from the west. Interlude (600→480): at 600 HP the mager-spawn timer pauses and resets, so kill the mager and push Zuk to 480. Phase 2 (480→240): Jad spawns — pray correctly against it, kill it, then bring Zuk down to roughly 300 and stop, so the healers and the next spawn do not overlap. Phase 3 (240→0): Zuk enrages and summons healers; tag and kill all four, restore your stats, and finish him. If Zuk lingers, one more mager/ranger pair appears — tag and pray the mager, and ignore the ranger if Zuk is nearly dead. When Zuk hits 0, every remaining monster dies with him and the run is won.

The headline reward is the untradeable infernal cape, the best melee cape in the game, awarded for defeating Zuk, along with up to 16,440 Tokkul (doubled with the Elite Karamja Diary). There is also a 1/100 chance of the Jal-nib-rek pet on a kill (1/75 if killed on a TzHaar Slayer task). You can hand unwanted infernal capes back to TzHaar-Ket-Keh for additional 1/100 rolls at the pet, raising your effective chance over time. Because the cape is a melee item, see our melee gear guide for where it fits in a melee setup.

• Greeding damage over the shield. The single biggest killer — getting an extra hit on Zuk is never worth stepping out of cover for one 148 hit you cannot pray.
• Letting the shield die. The shield only has 600 HP. Ignoring spawns while they batter it leaves you fully exposed to Zuk.
• Over-damaging Zuk into a threshold. Pushing past 480 without dealing with Jad, or dropping below 240 carelessly, stacks the healers and Jad on top of each other.
• Trusting the shield animation. Its drawn position lags its true position, so stay central or slightly forward rather than behind it.
• Resetting the wave. Logging out to change the shield's starting direction is counterproductive — Zuk now always goes the same way per run, and resetting just desynchronises his attack timings from the standard strategy.
