Item	What sources recommend
Armour	A 1.0 guide treats power level 7 desert gear as the floor. The wiki’s presets use Adamant (melee), Red Dragonhide (ranged) or Infinity Robes (magic) with an Amulet of Glory; its advanced presets add the Obsidian Cape.
Health	The wiki suggests collecting enough Sanguine Urns to raise your health before you go.
Weapons	A main weapon and a backup. A 1.0 player says their Abyssal Whip broke about three times in one run and the repair spell stripped its buffs. Bring a repair kit or Magical Mending.
Notable picks	The wiki’s advanced presets single out the Bow of Elidinis for its special attack; an Early Access run leaned on that special’s area water damage for all 30 waves. The wiki also names Pharaoh’s Sceptre, and an ascended Abyssal Whip or Zombie Axe.
Damage type	Water against every KotHaar (all listed as Water-weak). Fire and burn effects do nothing to them. For Fuzan, sources disagree; see section 4.
Food	Several stacks of cooked food. The wiki’s presets carry about 20 Stuffed Catfish or Eggs Royale; one Early Access run took stacks of 50 pumpkin soup and pumpkin drinks.
Strong Tea	The wiki calls it a must for the Fight Cave and suggests 10 or more. Its item page lists 10 hydration and 20 rest; make it at a Cooking Range from Ground Tea Leaves and 3 Clean Water.
Antifire	Super Antifire Potions for Fuzan: about 20 in the wiki’s presets, 10 or more in an Early Access run.
Drinks	The arena is always sunny, so Scorch builds and drains thirst. Carry drinks and use shade.
Buffs	Infusions, Whetstones or Magical Focus, made in advance. Ten seconds isn’t enough time to cook or craft.
Ammunition and runes	Enough for every combat style you carry.
Leave behind	Tools, building materials and anything else you won’t use in combat.

Enemy	Health (wiki)	What it does
KotHaar-Hur	660	Unarmed melee. It swings with one arm, then the other, and hops back when you get close (the wiki says within 25 metres).
KotHaar-Xil	660	The ranged caste: its journal describes weapons hurled at distant targets. The wiki page records no attack list.
KotHaar-Ket	990	Hammer swipes, a double-hammer special and a 16-metre earth spike. Below half health it raises a fire shield that blocks attacks, then explodes. Water damage breaks the shield.
KotHaar-Kal	2,475	Throws rings that deal ranged damage and burn. In the double throw the second ring tracks you unless you dodge. Its centre stab special can kill outright.
Tok-Xil	7,000	Mini-boss on waves 20 and 30. The wiki lists no attacks for it.

Wave	Enemies (community wiki, October 17, 2026 revision)	Threat or note
1	8 KotHaar-Hur	Melee only. Keep the pack together and spend as little stamina as possible.
2	3 KotHaar-Hur, 3 KotHaar-Xil	First ranged throwers. Use a pillar to break their line of sight.
3	2 KotHaar-Ket or 2 KotHaar-Xil (disputed)	The wiki’s text says Ket, but its icon and link point to Xil; its August 4 revision listed 2 Xil. A 1.0 guide says a central magma spout starts firing onto random tiles around here.
4	5 KotHaar-Hur, 5 KotHaar-Xil	Melee pack plus five throwers.
5	6 KotHaar-Hur, 1 KotHaar-Ket	First Ket: break its fire shield with water damage before it explodes.
6	4 KotHaar-Ket	Changed from 5 to 4 on October 16. Watch for several fire shields and earth-spike lines.
7	1 KotHaar-Kal	First Kal. Dodge the second, tracking ring; the centre stab can kill outright.
8	9 KotHaar-Hur	Largest melee pack so far. Keep an escape lane open.
9	1 KotHaar-Hur, 1 KotHaar-Xil, 1 KotHaar-Ket, 1 KotHaar-Kal	One of each caste: swings, thrown weapons, a fire shield and rings.
10	1 KotHaar-Ket	Single Ket. The quest trial is also ten waves, but no source checked confirms the two rosters match.
11	8 KotHaar-Hur, 1 KotHaar-Kal	A wiki note says the Hur keep respawning in sixes until the Kal dies, so kill the Kal first.
12	2 KotHaar-Kal	Two ring-throwers. Use pillars to fight one at a time.
13	7 KotHaar-Hur, 1 KotHaar-Ket	Melee pack plus a shielded Ket.
14	7 KotHaar-Hur, 5 KotHaar-Xil	Large mixed melee and ranged wave.
15	10 KotHaar-Ket	Ten fire shields and earth spikes; water damage pays off here.
16	1 KotHaar-Hur, 1 KotHaar-Xil, 1 KotHaar-Ket, 1 KotHaar-Kal	Same mix as wave 9.
17	6 KotHaar-Ket	More shields and spikes.
18	4 KotHaar-Xil, 2 KotHaar-Ket	The wiki flags the Xil count as possibly wrong; its August 4 revision listed 6 Xil and 1 Ket.
19	3 KotHaar-Hur, 1 KotHaar-Xil, 1 KotHaar-Ket, 1 KotHaar-Kal	Last wave before the first mini-boss. Check food, durability and ammunition.
20	Up to 20 KotHaar-Hur (in batches), 1 Tok-Xil	First Tok-Xil checkpoint. Focus it while you keep the Hur under control.
21	6 KotHaar-Hur, 1 KotHaar-Ket, 1 KotHaar-Kal	Unconfirmed on the wiki: the Hur may keep respawning until the Ket is defeated.
22	9 KotHaar-Ket (in batches)	They don’t all spawn at once.
23	4 KotHaar-Ket	Shields and spikes again.
24	1 KotHaar-Hur, 3 KotHaar-Xil, 3 KotHaar-Ket, 3 KotHaar-Kal (in batches)	Edited October 17; the previous entry listed 2 Xil and 1 Ket.
25	3 KotHaar-Kal	Checkpoint. Isolate one Kal behind a pillar instead of spreading damage across all three.
26	6 KotHaar-Ket	Target whichever enemy applies the most ranged or area pressure.
27	16 KotHaar-Hur, 8 KotHaar-Xil	Largest listed wave. The wiki says counts may be off by one; its August 4 revision said 10 of each.
28	3 KotHaar-Hur, 4 KotHaar-Xil, 2 KotHaar-Ket, 1 KotHaar-Kal	All four castes. Replace a failing weapon between waves, not during one.
29	2 KotHaar-Hur, 1 KotHaar-Xil, 2 KotHaar-Ket, 1 KotHaar-Kal	Last wave before the finale. Top up before the ten-second countdown ends.
30	2 Tok-Xil	Final wave. Kill one Tok-Xil at a time and keep off burning ground.
After 30	Fuzan	Same run, no restock. See section 4.

Phase (wiki numbering)	What happens	Response
1	Ground fight: claw sweep, stomps that launch lava spikes, a lava pool at his feet, arena-wide fire breath and fire rain.	Stay off hot floor; the wiki calls the centre safest at the start. Back off when lava pools under him.
2	He burns the floor and flies off. Power level 6 KotHaar Thralls spawn. He then crashes into the centre, moves, knocks down a wall and burns two sections.	Clear the Thralls, then leave the centre before he lands.
3	Two floor sections heat up; his regular attacks resume.	Fight from cool floor.
4	One hot section rotates counter-clockwise around the arena. He lands with four stomps.	Stand in the middle during the rotation, then move when he prepares to drop.
5	Four sections heat and two Thralls appear. A charge leaves spikes behind him. He then marks a player and chases them with dragonfire.	Keep dodging. The wiki says a Dragoncurse Shield plus antifire makes the dragonfire survivable.
6	Another charge, then regular attacks, with Thralls while he rains fire from the air.	Kill Thralls between fire-rain impacts; landing spots are marked.
7	The floor heats from both sides until one spot is left. He drops in for stomps and repeated charges.	Get to the last cool spot early and time your dodges.
8	Like phase 5, but three cool sections rotate and several Thralls spawn before he lands.	Stay central, clear the Thralls, then dodge the landing stomps.

Fire Cape	Value (community wiki)

Problem	What’s been reported	What to check
Disconnected mid-run	An October 16 Steam post, after 1.0.1, describes disconnections on waves 23 and 27, the poster’s only ones in about 100 hours of play. In Early Access, a co-op pair hard-crashed at round 23. Jagex’s October 15 known-issues post doesn’t list it.	No fix is published. Expect to restart from wave 1. Note the wave, platform and who hosted, then report it. Jagex’s 0.12 vital-information page pointed players to the official Discord’s Bug Reports channel.
Fuzan stuck at 1% or never returns	Early Access reports describe Fuzan freezing near 1% or flying off and not returning, often linked to fighting from the pillars. Jagex’s 1.0 notes fix him getting stuck at 0 HP in the Fight Caves; 1.0.1 fixes him turning passive and invisible after some player deaths.	Update to 1.0.1 and fight on the floor. Reports treat the fight as bugged if Thralls stop spawning during the rotating floor. One Early Access tip was to kite the final Thralls until the floor finishes its cycle.
Fire Cape didn’t drop	An Early Access player cleared 30 waves and both Tok-Xil but got no cape; a reply says Fuzan must be beaten again after wave 30. Other players lost the cape when Fuzan bugged.	Confirm you chose the 30-wave mode, not Trials of Fuzan, and killed Fuzan in the same run. Check your inventory, Key Items and crafting menu for a recipe (see section 5).
Cape moves to your bag after loading	Early Access players found it unequipped whenever they loaded a world; a reply suspected it was a side effect of the fix for a Fire Cape sign-in error (0.12.0.7). The wiki credits 1.0 with ending this. Jagex’s published 1.0 notes checked here don’t mention it.	Re-equip it from your inventory after each world load.
Portal to the Fight Cave is gone	An October 9 Steam post says the portal vanished after the player teleported home for food, and the quest NPC still asked for mirrors that were already installed. It has no replies, and Jagex lists no fix.	Go to the volcanic gateway at the base of Fuzan’s volcano in The Burning Spire, where the wiki places the entrance, and re-read the quest objective. Back up your save before experimenting, then report it with the quest text.
Enemies stuck in walls or invisible fire	An October 7 post says Fight Cave enemies sometimes fail to spawn or get stuck in walls. In Early Access, players burned on invisible fire left by Tok-Xil until a 0.12.1.4 fix.	Melee can’t reach a stuck enemy; the October 7 poster suggests magic users fire into the lava to find it. Note the wave for a bug report.
Co-op Fuzan arena looks wrong after a death	An Early Access report says that when a non-host player dies and returns, their arena resets and desyncs: missing shade, walls that aren’t there.	The host’s view is reported as correct. Record which player desynced.
