The Frostspire Expanse update in The Forge introduced some of the most demanding late game content so far. Among the new caves, enemies, and quests, one item stands out as especially rare and frustrating to obtain the Stolen Heart.
This ore is required to complete the final Raven quest and unlock the Berserker Armor recipe.
In this guide, you will learn exactly where the Stolen Heart comes from, how to mine it efficiently, and what it is used for.
How to Obtain the Stolen Heart in The Forge
The Stolen Heart is not dropped by enemies. It is obtained by mining a special late game rock called Heart of the Island.
Before you can even attempt to get it, you must meet the following requirements:
- You must be level 70
- You must unlock Frostspire Expanse on Island 3
- You must complete Raven Quest 1 and Raven Quest 2
- You must unlock and enter Raven Cave
Once Raven Cave is unlocked, head inside and explore deeper sections of the cave. You are looking for a distinct crystal rock with a glowing red orb floating in the center. This rock is the Heart of the Island.

Heart of the Island Mining Details
Heart of the Island rocks have extremely high durability and strict requirements.
- The rock has approximately 32,500 HP
- It requires at least 650 mining power
- Prismatic Pickaxe or Dragon Head Pickaxe is strongly recommended
When you begin mining, pay close attention to the ore visible inside the rock. Each Heart of the Island yields only one ore.
The Stolen Heart is not guaranteed. It has an extremely low drop chance.
- Drop rate: 1 in 54,321
If the ore visible inside is not a Stolen Heart, stop mining and leave the rock partially intact. The rock will eventually regenerate, allowing you to retry without fully breaking it and wasting time.
Repeat this process until you visually confirm the Stolen Heart inside the rock, then fully mine it.
This method saves hours of unnecessary grinding.
Best Pickaxe to Mine Stolen Heart
Due to the HP and mining power requirement, using anything below a Prismatic Pickaxe is not viable.
Recommended pickaxes:
- Prismatic Pickaxe
- Dragon Head Pickaxe
Using mining runes and luck boosting effects can help reduce farming time, although luck does not increase the drop rate directly. It only helps with efficiency.

What Is the Stolen Heart Used For in The Forge
The Stolen Heart has one primary purpose and one indirect value.
Raven Quest Requirement
The Stolen Heart is required for Raven Quest 3, which asks you to:
- Kill Mini Demonic Spider 25
- Kill Demonic Spider 10
- Kill Demonic Queen Spider 1
- Bring Stolen Heart 1
Completing this quest rewards you with the Berserker Armor recipe, one of the strongest late game armor options in The Forge.
Forging Value
While the Stolen Heart is mostly quest focused, it is also a high tier forging component and should not be wasted casually. Due to its rarity, most players reserve it strictly for quest completion.
FAQs About Stolen Heart in The Forge

No. The Stolen Heart has an extremely low drop rate of 1 in 54,321 and is not guaranteed from each rock.

Final Words
The Stolen Heart is one of the rarest progression items in The Forge and is intentionally designed to test patience and preparation. If you rush into Raven Cave without proper mining power, you will waste time and effort. Approach it strategically, check the ore before fully mining, and be ready for a long grind.
Once obtained, it marks a major milestone in Frostspire Expanse progression.
