Gilded Fossil is a fossil type. Fossils are a special type of currency introduced in the delve league that can be socketed into resonators to modify the crafting behavior in specific ways. Fossils can also add special Delve modifiers.
This fossil adds an implicit mod with the description
Item sells for much more to vendors, which does not overwrite the item’s current implicit. The actual mod is chosen from a selection of random implicit mods that adds various currency items to the vendor price.
The result is RNG. The actual mods rolled on your item have no effect whatsoever. You could have a level 1 Driftwood Wand with "10 spell damage/mana on kill" or other normal items that sells for 2 Mirror Shards. However, the chance depends on the Spawn Weight, just like a gamble.
Note: Using a Fractured Fossil to mirror an item with the “Item sells for much more to vendors” implicit modifier now generates a new vendor sell price on the Mirrored copy.
For example, a rare Stygian Vise belt with mods “Item sells for much more to vendors” may exchange for an Orb of Alteration, one Exalted Orb, 2 Alteration Shards, and 6 Alchemy Shards.
The spawn weight for Mirror Shard is 1 and rewards 2 Mirror Shard. There is a total of 9 possibilities with varying weights, from one with weight 1 and one with weight 10 through to four with weight 6000. Total weight: 23011, so about .00004346 or .004346% chance to get 2 Mirror Shards. Also, the Exalted Orbs chance are surprisingly “common” at a 4.346% chance (1000 weight). Albino feathers are the 2nd rarest at 10 weight.
The drop location of Gilded Fossil is Azurite Mine. Standing on any Waypoint, click the flashing candle icon: "Click to travel to the Mine Encampment", then you will go to the Azurite Mine.
There are two ways to obtain Gilded Fossil.
Sometimes, Niko the Mad sells a Gilded Fossil for 100 000 Azurite. Niko is one of the five masters. He provides introduction to delves and appears when harvesting Voltaxic Sulphite. He also sells Fossils and Resonators for Azurite.
In addition, you can also exchange currency items for it. The price of Gilded Fossil is 3 Chaos Orbs.
Place a Gilded Fossil in a Resonator to influence item crafting.
