Crafting Infernal Plate Armor in Old School RuneScape

For players diving into high-level skilling and gear progression, crafting your own infernal plate armor is one of the more involved-but rewarding-processes in Old School RuneScape. Whether you’ve been unlucky with drops or simply prefer a self-sufficient approach, this guide walks you through the entire process, from gathering materials to forging the final armor piece, though some players may opt to buy OSRS gold to ease the grind and acquire materials more quickly.

Requirements and Materials

Before starting, make sure you meet the following requirements:

· 78 Mining

· 83 Smithing

· Tools: Pickaxe, Chisel, Hammer

For each armor piece, you will need:

· 450 Plate Shards

· 2,520 Crushed Infernal Shale

If you're crafting multiple pieces, scale these numbers accordingly. Gathering these resources is the most time-intensive part of the process, so prepare for a grind.

Step 1: Mining Infernal Shale

Begin by heading to the Chasm of Fire, specifically the lower level near the entrance to Yama’s Lair. Instead of entering the lair, move toward the northeast corner and pass through the fire barrier. This area contains Infernal Shale deposits, your primary resource.

There are three main approaches to mining:

· AFK Method (Deposits): Mine large deposits for a more relaxed, low-effort experience. Ideal if you prefer minimal attention.

· Active Method (Rocks): Mine individual shale rocks for slightly better efficiency.

· Tick Manipulation (Advanced): Speak to the nearby imp to obtain a handkerchief, allowing for tick manipulation. This is the fastest method but requires constant input and precision.

Once your inventory is full, use a chisel on the shale to convert it into crushed infernal shale, which is stackable. Repeat this process until you reach the required amount (2,520 per armor piece).

Expect this step alone to take several hours-approximately 4–6 hours depending on your method and efficiency.

Step 2: Creating Infernal Blend

With your crushed shale and plate shards ready, move to the furnace located in the same area.

The conversion ratio is:

· 28 Crushed Shale : 5 Plate Shards

Use both materials on the furnace to create an infernal blend. Once the process begins:

· Click the furnace to initiate heating.

· Move to the adjacent rockpool to cool the mixture.

· Monitor the progress bar-wait until it fills and empties before returning to the furnace.

Important: If you remove the mixture too early, it becomes a malformed rock, which must be reheated before continuing.

Repeat this cycle until you produce 10 infernal nuggets. These will automatically combine into an infernal chunk when used on the furnace.

Step 3: Forging Infernal Plates

Take your infernal chunk to the nearby anvil. This step introduces a timing-based mechanic:

· Click the anvil in sync with the hammer sparks.

· Clicking too early or too frequently will reset progress.

This process may feel unintuitive at first, but with practice, you’ll find a rhythm. Successfully completing the sequence converts the chunk into an infernal plate.

Each armor piece requires:

· 9 Infernal Plates

Step 4: Smithing the Armor

Once you’ve forged all required infernal plates, remain at the anvil to smith your final armor piece. This is the simplest step mechanically, but it represents the culmination of several hours of preparation.

The result is a piece of infernal plate armor, often considered among the most visually striking gear sets in the game.

Time Investment and Efficiency Notes

In total, this process can take around 5 hours per armor piece if done using AFK methods. However, more active strategies—such as efficient mining routes or tick manipulation-can significantly reduce this time.

If you're optimizing for speed:

· Prioritize manual rock mining over deposits.

· Use tick manipulation if comfortable with high-intensity gameplay.

· Minimize idle time during furnace and anvil phases.

Final Thoughts

Crafting infernal plate armor is not a casual undertaking, but it’s a satisfying goal for players who enjoy resource management and production chains. It also provides a reliable alternative to RNG-based drops, especially if luck hasn’t been on your side, though some players may choose to supplement their progress with cheap OSRS gold to speed up resource acquisition. If nothing else, mastering this process gives you a deeper understanding of OSRS’s layered skilling systems-and a solid piece of armor to show for it.
