The guide is written with the goal of idling the dungeon. If you want to do it manually, the requirements are much more relaxed, although the more DR you have, the easier it is to do anyway.

Why clear Volcanic Cave?

On each clear, you get the Fire Cape that gives 2% DR.

Volcanic Cave

is the place where you gear up in preparation for the

Error creating thumbnail: File missing

Air God Dungeon

. According to the simulation, it takes 820 clears to get the full ancient set with 75% probability and 1350 clears to get it with 95% probability.

It is also a place to farm 10 Amulets of Fury for FEZ. Check the FEZ/Guide to see if it's the best option for you.

After you clear the Volcanic Cave 100 times, you will unlock Ancient Magicks -

Slicing Winds

,

Error creating thumbnail: File missing

Icicle Volley

, and

Error creating thumbnail: File missing

Ignite

.

Error creating thumbnail: File missing

Winds

are used when the hit chance of everything else is not high. They don't miss if you have more than 20k accuracy;

Error creating thumbnail: File missing

Ignite

is used to one-shot;

Error creating thumbnail: File missing

Volley

is used for everything else. Ancient Magicks are not affected by damage amplification in any way except the Combat Triangle. No curses, no debuffs, no gear buffs. However, it is much stronger than the basic magic at this stage. For instance, when basic magic could clear

Volcanic Cave

8 times per hour, Ancient Magicks could do it 22 times.

Gear to idle

The main heavy-hitter of the

Error creating thumbnail: File missing

Volcanic Cave

uses the

Error creating thumbnail: File missing

Melee

style. Therefore, clearing it with pre-Volcanic

Error creating thumbnail: File missing

Ranged

build is unfeasible due to the Combat Triangle penalties. It is assumed that you have

Error creating thumbnail: File missing

Auto Eat - Tier III

. All calculations are done for the

Error creating thumbnail: File missing

Hardcore

and Adventure game modes. For

Error creating thumbnail: File missing

Standard, the restrictions are a bit more relaxed.

Melee

Error creating thumbnail: File missing

Volcanic Cave

is usually done with

Error creating thumbnail: File missing

Melee

because the dragon armor set requires only

Error creating thumbnail: File missing

Level 99

to produce. It then can be trimmed to provide 30% DR. Below is the melee build that requires

820

Error creating thumbnail: File missing

Hitpoints

to idle the dungeon on any game mode. However, pay attention that even slightly less DR or HP will mean death for this build because it hangs a hair breadth away from the max hit of Malcs. Check with Can I Idle or Combat Simulator to see if you can idle with your build. Also, the Sandstorm Ring is very important for your clear time.

Item	DR
(G) Dragon Helmet	6%
(G) Dragon Platebody	6%
(G) Dragon Platelegs	6%
(G) Dragon Boots	6%
(G) Dragon Shield	6%
Paladin Gloves	4%
Knight's Cape	1%
Elite Amulet of Defence	2%
Sandstorm Ring	0%
Sunset Rapier	0%
Total	36%

Pre-Volcanic Magic

The other possible option is

Error creating thumbnail: File missing

Magic

. Clearing the Volcano with Magic from the start is not recommended because its adjusted clear time is slower than the Rapier's. To idle the dungeon with the build below, you need

800

Error creating thumbnail: File missing

Hitpoints

and

Error creating thumbnail: File missing

Weakening III

active.

Item	DR
Fire Expert Wizard Hat	5%
Fire Expert Wizard Robes	5%
Fire Expert Wizard Bottoms	5%

(U) Ancient D-hide Vambraces	6%
Skull Cape	3%
Elite Amulet of Defence	2%
Silver Diamond Ring	1%

100-Volcanoes Magic

After clearing the

Error creating thumbnail: File missing

Volcanic Cave

100 times, you will unlock Ancient Magicks. It's theoretically possible to farm the Volcanic Cave with the 20k-accuracy

Error creating thumbnail: File missing

Slicing Winds

on the following build if you have

920

Error creating thumbnail: File missing

HP

,

Error creating thumbnail: File missing

Level 93

, and a

Error creating thumbnail: File missing

Stone Skin

prayer active. To farm the dungeon with 34% DR and without the prayer or potions, you need

940

Error creating thumbnail: File missing

HP

. Your biggest threat is Prat, the Protector of Secrets with the resulting damage of 375 and your minimum HP being 377. Check if you fulfill the accuracy quota with Combat Simulator. The 20k accuracy is important because after that number

Error creating thumbnail: File missing

Slicing Winds

cannot miss, becoming a top-DPS spell against the dungeon at this point of progression.

Item	DR
Ancient Wizard Hat	5%
Ancient Wizard Robes	5%
Ancient Wizard Bottoms	5%
Ancient Wizard Boots	5%
(U) Ancient D-hide Vambraces	6%

The Combat Simulator stats per hour are the following:

Prayer points	7182
Whales	394.2
Runes	17050

Weapon choice

The information in the table below was produced by using the Combat Simulator and the respective builds above.

Details
The clears per hour are counted for a Hardcore character with level 70 in everything except level 82 Error creating thumbnail: File missing HP. The Error creating thumbnail: File missing Weakening III is active with the pre-Volcano Magic. The Error creating thumbnail: File missing Stone Skin is active with the 100-Volcano Magic. The prayer level is adjusted to allow this prayer. The adjusted clear time is calculated with the notation and assumptions from the Dragons Den/Guide, but Whales are used as food instead of Crabs. The Rune-related part of Pre-Volcanic Magic is approximated as [math]\displaystyle{ T_m + T_r = N * (9.75 + 1.72) / 16 * 1.3 + N * (9.75 + 1.72) * 2 / 16 = 37.851 * N / 16 }[/math] where [math]\displaystyle{ N }[/math] is the number of Ancient runes spent, [math]\displaystyle{ 9.75 }[/math] is for Error creating thumbnail: File missing Fire Surge, [math]\displaystyle{ 1.72 }[/math] is for Error creating thumbnail: File missing Weakening III. The Rune-related part of 100-Volcanoes Magic is approximated as [math]\displaystyle{ T_m + T_r + T_p = N_o * (2 + 1.3) / 16 + N_p * 3.6 / (3 * 4) = 3.3 * N_o / 16 + 0.3 * N_p }[/math] where [math]\displaystyle{ N_o }[/math] is the overall number of runes spent, [math]\displaystyle{ N_p }[/math] is the number of prayer points spent. The formula is the one of Alt.Magic/Blessed Offering. The gain rates of other ways are shown on the Error creating thumbnail: File missing Prayer page.

Item	Raw clears per hour	Adjusted clear time (s)
Dragon Sword	14.11	895
Ancient Sword	14.7	833
Dragon Claw	15.3	813
Sunset Rapier	16.5	742
Ancient Claw	17.5	799
Pre-Volcanic	9.28	2302
100-Volcanoes	38.79	440

It should be noted that the Melee clear times become tremendously worse without the Sandstorm Ring. Only Rapier and Ancient Claw are better than pre-Volcano in this case.

It is suggested to start using the 100-Volcanoes build as soon as you can because the Prat and Malcs significantly slow your clear time by high evasion. 20k Slicing Winds don't miss.

Gear options

Gloves

Item	DR	Requirements
Paladin Gloves	4%	none
(U) Red D-hide Vambraces	4%	Error creating thumbnail: File missing Level 60
(U) Black D-hide Vambraces	5%	Error creating thumbnail: File missing Level 70
(U) Ancient D-hide Vambraces	6%	Error creating thumbnail: File missing Level 80

The Ancient vambraces drop from the

Error creating thumbnail: File missing

Dragons Den

. You will very likely need them to idle the

Error creating thumbnail: File missing

Air God Dungeon

, so might as well get them now.
The Red and Black vambraces can be either crafted with

Error creating thumbnail: File missing

Crafting

or dropped from the

Error creating thumbnail: File missing

Spider Forest

.

Or you might just farm some Paladins for their Gloves.

Cape

Item	Upside	Downside
Knight's Cape	1% DR	Error creating thumbnail: File missing Level 88 unique drop
Skull Cape	3% DR	Screws up Error creating thumbnail: File missing Melee accuracy
Firemaking Skillcape	XP boost	Error creating thumbnail: File missing Level 99, no DR increase
Obsidian Cape	Spend less food	Rare drop, no DR increase
Fire Cape	2% DR	You need to clear Error creating thumbnail: File missing Volcanic Cave once

Boots

The choice of boots is small because we don't want to drop in DR too much.

Item	DR%	Requirements
(G) Dragon Boots	6%	Error creating thumbnail: File missing Level 60
(G) Rune Boots	5%	Error creating thumbnail: File missing Level 40

Ring

Item	Benefit
Sandstorm Ring	Insane clear speed buff for Melee
Silver Diamond Ring	1% DR
Aorpheat's Signet Ring	5% chance to double Elite Chest and 100% more money
Ring of Wealth	7% chance to double Elite Chest
Gold Sapphire Ring	30 reflect to clear the dungeon a bit faster

Conclusion

The suggested order of actions is as follows:

Sunset Rapier,
Sandstorm Ring,
100 Volcanic clears as melee,
The rest of Volcanic clears as Ancient Magick.
