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:

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

Fossils Farming Guide

1. Killing biomes in Azurite Mine

Azurite Mine is the only drop location for fossils. Slain biomes and you will obtain different fossils. If you want to get special fossils, you can see the Azurite Mine Biomes Location table above. The higher the depth you go, the more valuable loots you will get.

2. Buy fossils from Niko.

Niko, Master of the Depths, lives in the Azurite Mine. He provides introduction to delves and appears when harvesting Voltaxic Sulphite. He also sells Fossils and Resonators for Azurite.

3. Buy fossils from other players

This is the fastest way to obtain fossils in the Path of Exile. Just farming PoE currency and using it to exchange for your fossils. The following is the reference prices:
