Why Clear Infernal Stronghold?
There three main reasons for completing the
Error creating thumbnail: File missing
Infernal Stronghold:
- Clear it once after 100 Error creating thumbnail: File missingVolcanic Caves to get the
Infernal Cape that has 4% DR. - Clear it 10 times to get 10
Infernal Cores to complete a township task, and to merge 
Dragon Claw and 
Ancient Claw into 
Infernal Claw. - Clear it 100+ times to complete more township tasks, or earn a lot of
.
Manual-Eating Build
The guide assumes that you have completed
Error creating thumbnail: File missing
Volcanic Cave at least once, and have obtained the Ancient Claw. If not, then check out this Ancient Claw Guide for how to obtain this key item.
Before attempting
Error creating thumbnail: File missing
Infernal Stronghold, it is strongly recommended that your
Error creating thumbnail: File missing
Auto Eat threshold is higher than all of 
Malcs moves when you are not stunned. This build can achieve that with 900 HP, although it is advised to check it with the Combat Simulator to be sure.
The boss in this dungeon is Malcs, the Leader of Dragons (Malcs), and the strongest attack is the combination of Sealing (Stun) + Penetrating Claws.
| Slot | Item | DR% |
|---|---|---|
 |  (G) Ancient Helmet | 7% |
 |  (G) Ancient Platebody | 7% |
 |  (G) Ancient Platelegs | 7% |
 |  (G) Dragon Boots | 6% |
 |  (U) Ancient D-hide Vambraces | 6% |
 |  Fire Cape | 2% |
 |  Elite Amulet of Defence | 2% |
 |  Sandstorm Ring | 0% |
 |  Ancient Claw | 0% |
 |  (G) Ancient Shield | 7% |
| Total | 44% | |
The Ancient Claw can be substituted for the 
Sunset Rapier at a push, but due to the boss stun attack being very powerful, the faster you can attack after stun, the better your overall chances.
Use prayers to increase your accuracy, as without your hit chance against Malcs will be very low e.g. ~25% without prayers, compared to ~40% with. Using 
Diamond Luck Potion (any level) will give you a significant advantage.
Equipping the Infernal Cape after the first clear as this will increase DR, and will make it easier to get the 10 Infernal Claw needed for upgrading.
The 
Dragonfire Shield (DFS) which can be obtained from the
Error creating thumbnail: File missing
Volcanic Caveis another good option, and can be paired with
Error creating thumbnail: File missing
Icicle Volleyand
Error creating thumbnail: File missing
Witch. This combination is very effective against the 
Green Dragon. Similarly, with at least 20,000 Accuracy
Error creating thumbnail: File missing
Slicing Windsis another good option.
The DFS is one of the best defences against Malcs. However, for an extra increase in DR, consider equipping 
Silver Diamond Ring. Doing so will reduce your Dungeon clear time, but may increase your chances of survival. With DFS equipped as well as 990 HP it should be sufficient to clear this dungeon with ease.
Malcs Special Moves
Pay attention to the following special moves from Malcs:
- Sealing + Penetrating Claws: do not underestimate this combo. The Spam Eating kicks in with a delay after you push a keyboard button, so it is important that you start before the Penetrating Claws hit you. This special move has two instances of damage separated by a short gap, so a good idea to use Spam Eating. The damage from Penetrating Claws is calculated as [math]\displaystyle{ 640 \times (1-\text{DR}) \times 1.3 \times 2 }[/math].
- Sealing + Tail Whip: Heal to full HP before this hits, and if you have time, look what the max damage of the Tail Whip is when you are stunned. You may find that you can delay manual eating depending on whether your HP allows. The damage from this move can be calculated as [math]\displaystyle{ 690 \times (1-\text{DR}) \times 1.3 }[/math].
- Sealing + Usual Attack: Occurs when Malcs uses two Sealing attacks in row. The approach given in Tail Whip works well here.
- Sealing + Inferno: Not as strong as the other attacks, and one that you can normally rely on Error creating thumbnail: File missingAuto Eat to survive.
Idling Options
This build relies on high DR and a high HP and the top tier of
Error creating thumbnail: File missing
Auto Eatand uses melee as this gives a high amount of damage reduction (DR). If your consumables run out, then you will not survive, so be sure that you have enough in the bank before you begin idling.

The 
Prayer Scroll or 
Alchemist's Bag can be used to reduce prayer costs and the number of potions needed to idle the Infernal Stronghold.
Alternative options are available if the
Error creating thumbnail: File missing
Air God Dungeon has been completed. The 
Aeris God Gloves and 
Aeris God Boots each give an additional 2% DR. Similarly, once the
Error creating thumbnail: File missing
Infernal Stronghold has been completed the Infernal Cape can give another 2% DR. In
Error creating thumbnail: File missing
Agilitythe
Error creating thumbnail: File missing
Lake Swimcan be used to give an extra +1% DR.
Once you have sufficient DR to idle comfortable, you can also consider wearing the 
Chapeau Noir for a 10% chance of doubling the items received, which can reduce the number of dungeons needed.
Agility
Bonuses from Agility Obstacles can reduce the amount of DR required considerably by increasing your Maximum Hitpoints.

For example, for an idle build with
Error creating thumbnail: File missing
Level 90, the DR required would drop from 59% down to 54%. Similarly, 
Finn, the Cat increases your HP, and so an build with
Error creating thumbnail: File missing
Level 91(with a total HP of 1060) would only need 53% DR. Lower DP also can reduce the need for potions, Prayers and the
Error creating thumbnail: File missing
Witchsummon. When combined with all of the equipment improvements mentioned earlier results in a lower minimum HP of around
Error creating thumbnail: File missing
Level 76. The use of
Error creating thumbnail: File missing
Cliff Balancewill use +2 extra prayers, but carries a lot of benefits.
After Water God Dungeon
With access to magic armor with late-game DRs, you can now take on this dungeon with proper Combat Triangle advantage, meaning no need for expendable resources besides food and runes, no need for agility boosts, and even still enough DR to spare some for item doubling.
| Slot | Item | DR% |
|---|---|---|
|  Chapeau Noir | 0% |
|  Glacia God Platebody | 8% |
|  Glacia God Platelegs | 8% |
|  Glacia God Boots | 8% |
|  Glacia God Gloves | 8% |
|  Skull Cape | 3% |
| Elite Amulet of Defence | 2% |
|  Ring of Wealth | 0% |
|  Fire Imbued Wand | 0% |
|  Scaled Shield | 8% |
| Total | 45% | |
Instead of the 
Ring of Wealth, a 
Aorpheat's Signet Ring can be used; it will give you an additional 100k-150K GP per clear, but only a 5% chance to double Infernal Core drops, making it worse for those farming only Infernal Cores but better for those also farming GP.
For those who have already acquired their Infernal Claw, thus exclusively interested in GP, please see the Combat section of the Money-Making Guide.
