PoE Fossils
Fossils are a complex but powerful crafting system in Path of Exile, introduced in the Delve league. They can be used to modify specific aspects of equipment, allowing players to create extremely powerful gear. Here's a breakdown of the key points:
What are Fossils?
- Special currency items used in conjunction with Resonators to modify equipment crafting.
- Found in the darkness between Delve nodes, behind Fractured Walls, and through various other sources.
- Each Fossil has specific effects that influence the crafting outcome when used with a Resonator.
How do Fossils work?
- You socket Fossils into the empty slots of a Resonator (another currency item).
- When you use the Resonator on an item, the combined effects of the Fossils influence the potential modifiers rolled on the item.
- Each Fossil typically has several tiers, with higher tiers offering stronger or more specific effects.
Types of Fossils:
- There are numerous Fossils, each categorized by their influence on crafting:
- Affliction: Add mods related to elemental damage or ailments.
- Ancestor: Add life, energy shield, or mana modifiers.
- Corroded: Chance to add corrupted modifiers or re-roll existing ones.
- Facetted: Add dexterity, intelligence, or strength modifiers.
- Fractured: Add defense-related modifiers or fossils behind fractured walls.
- Glyphic: Add critical strike or accuracy modifiers.
- Hollow: Add utility or aura modifier options.
- Perfect: Increase the chance of rolling high-tier modifiers.
- Sanctified: Add chaos damage, chaos resistance, or vaal skill modifiers.
- Shuddering: Add physical damage or attack speed modifiers.
Tips for using Fossils:
- Understanding the specific effects of each Fossil is crucial for utilizing them effectively.
- Experimenting with different Fossil combinations and Resonator charges can yield powerful results.
- Resources like poe.ninja and the PoE Wiki offer detailed information and guides on Fossil crafting.
Additional points:
- Fossils can be used on various equipment types, including weapons, armor, and accessories.
- The effects of Fossils can be combined with other crafting methods for even more control over the crafting process.
- Fossil crafting can be quite expensive and resource-intensive, so understanding the risks and rewards is important.
I hope this comprehensive overview of Fossils in Path of Exile gives you a good starting point.

Fossil Biomes and Depth
Fossil can be only dropped in the Azurite Mine. The Azurite Mine contains 7 common biomes and 3 city biomes, each with different monsters, encounters, and common fossil drops. You can farm Fossils by the following Biomes:
| Biome | Fossils by Rarity | Minimum Depth | |
|---|---|---|---|
| Depth | Weight | ||
| Mines |  Metallic Fossil,  Serrated Fossil,  Pristine Fossil,  Aetheric Fossil |
0 | 100 |
| 40 | 100 | ||
| 65 | 0 | ||
| Fungal Caverns |  Dense Fossil,  Aberrant Fossil,  Perfect Fossil,  Corroded Fossil,  Gilded Fossil |
4 | 0 |
| 20 | 100 | ||
| Petrified Forest |  Bound Fossil,  Jagged Fossil, Corroded Fossil,  Sanctified Fossil |
4 | 0 |
| 20 | 100 | ||
| Abyssal Depths | Aberrant Fossil, Bound Fossil, Gilded Fossil,  Lucent Fossil |
10 | 0 |
| 25 | 100 | ||
| Frozen Hollow |  Frigid Fossil, Serrated Fossil,  Prismatic Fossil, Sanctified Fossil |
200 | 0 |
| 40 | 100 | ||
| Magma Fissure |  Scorched Fossil, Prismatic Fossil, Pristine Fossil,  Enchanted Fossil,  Encrusted Fossil |
30 | 0 |
| 50 | 100 | ||
| Sulfur Vents | Metallic Fossil, Perfect Fossil, Aetheric Fossil, Encrusted Fossil |
55 | 0 |
| 75 | 100 | ||
| Vaal Outpost(city biome) | Boss: Ahuatotli, the Blind. The boss can only spawn below 35 depth. A city biome will spawn, which contains better loot and rarely, a special boss, but are much more difficult and denser. | 22 | 0 |
| 83 | 12 | ||
| 600 | 18 | ||
| Abyssal City(city biome) | Boss: Kurgal, the Blackblooded. The boss can only spawn below 110 depth. | 82 | 0 |
| 83 | 4 | ||
| 220 | 12 | ||
| 600 | 18 | ||
| Primeval Ruins(city biome) | Boss: Aul, the Crystal King. The boss can only spawn below 171 depth. | 219 | 0 |
| 220 | 4 | ||
| 600 | 12 | ||
Current theory on weights: The weight is scaled between the lower and upper entries based on current depth. See the table below for data mined values. Take Magma Fissure biome as an example:
| Depth | Weight |
|---|---|
| 30 | 0 |
| 50 | 100 |
If your character is below or at depth 30, the biome will not spawn. If your character is between 31 and 50, the biome will spawn and the weight will increase accordingly;
- Depth 31, 5 weight
- Depth 32, 10 weight
- …
- Depth 49, 95 weight
- Depth 50, 100 weight
