Why Clear Dragons Den?

Dragons Den is usually cleared for the Ancient Crossbow, (U) Ancient D-hide Vambraces, and (U) Ancient D-hide Shield because they are wanted for the Air and Water God Dungeons. The (U) Ancient D-hide Shield can be upgraded into the Scaled Shield, a bis ranged shield for a very long time.

Other parts of the Ancient set are of little importance because you will use the Aeris God Armour for the Water God Dungeon. Keep them only if you didn't already get your Ranged to level 85.

Gear to idle

Because all enemies in Dragons Den are Melee, it is advised to use a Magic or Melee build due to the Combat Triangle.

This guide assumes that you have Auto Eat - Tier III. Crabs were used as a food of choice to reflect the approximate cooking level at the time of clearing the dungeon.

The simulations are run on a character with lvl 80 in all combat skills except Hitpoints.

Due to the wide range of cases, it is recommended to use the Combat Simulator to compare the options tailored for your situation.

The ring slot in the given builds is free. It is suggested to use Ring of Wealth if you have it or Aorpheat's Signet Ring otherwise.

According to the simulation - it takes, on average, 506 Elder Chest opens to obtain all items from the Dragons Den. It takes 657 opens to obtain all items from the Dragons Den with a 75% probability and 1165 opens to obtain all items with a 95% probability.

Basic Magic

Below is a basic build that needs Runecrafting Level 90 to create, Magic Level 78 to wear, and 870 HP to idle.

The spell of choice is Fire Surge with combination runes.


The following build needs Smithing Level 99 to create, Attack Level 70 to wear, and 780 HP to idle.

Advanced Magic

For comparison, here's the magic build that takes less time to acquire than the Ancient Claw and needs 860 HP to idle.

Adjusted Clear Time

Adjusted clear time is the time it takes to prepare all needed food and runes plus the time of the clear itself.

Build Adjusted clears per hour
Sunset Rapier 3.7
Basic Magic 4.1
Ancient Claw 4.1
Advanced Magic 5.8
Adjusted clear time [math]\displaystyle{ A }[/math] is calculated by dividing the overall time [math]\displaystyle{ T_{all} }[/math] by the number of dungeons [math]\displaystyle{ D_h }[/math] cleared per one hour.

The overall time [math]\displaystyle{ T_{all} }[/math] is calculated by the sum of one hour plus the time required to produce the Crabs [math]\displaystyle{ T_c }[/math], mine essence [math]\displaystyle{ T_m }[/math], and create runes [math]\displaystyle{ T_r }[/math]. All measured in seconds. The number of spent Ancient runes is noted as [math]\displaystyle{ N }[/math].

The Crab total preparation time is 6.9 seconds per Crab.

The Fire Surge with the combination runes is used.

The approximate Adventure situation is taken for Runecrafting. In particular, Mining Gloves and Elemental Potion are not used. The Runecrafting 95% milestone of the mastery pool is active, and the runes have 99 mastery, meaning that 16 runes are produced per two seconds. No rune preservation or doubling.

The mining time is the one with the Dragon Pickaxe upgrade - 1.3 seconds. The number of needed essence considers all runes used in crafting: Essence, Air, Fire, Smoke and Ancient runes.

[math]\displaystyle{ T_m = N * (7 * (2/16 + 2/16) / 16 + 1 / 16 + 7 / 16) * 1.3 = N * (7 * (2/16 + 2/16) + 1) / 16 * 1.3 + 7 / 16 * 1.3 }[/math]

For [math]\displaystyle{ T_r }[/math] compared to [math]\displaystyle{ T_m }[/math], the difference is that we don't account for one rune essence in the Smoke Rune because we don't need to runecraft it separately unlike all other parts of the formula.

[math]\displaystyle{ T_r = N * (7 * (2/16 + 2/16) + 1) / 16 * 2 }[/math]

You can check out the intermediate steps with the following Google Sheet (link).

Advanced Magic is the clear leader, therefore it is recommended to farm the Dragons Den dungeon with the Advanced Magic build.

Food Expenditure

The bulk of time is spent on preparing food, so it's heavily recommended to level your food-producing methods when possible. As an example, with some upgrades ( Fishing Skillcape, Cooking Skillcape, 99 mastery, top fishing rod, Amulet of Fishing), the fishing and cooking times are the following:

Food Fishing time (s) Cooking time (s) HP HP per second
Whale (Perfect) 1.97 9.35 580 51.2
Crab 0.96 5.95 150 21.7

In other words, if you prepare Whales instead of Crabs, you would more than double your speed of food preparation, which is a huge boost to the clear time.
