Mechanics

This fossil adds an implicit mod with the description Item sells for much more to vendors. This implicit mod is separate from the item's actual implicit mod(s) and will not overwrite other implicit mods when applied, including implicit modifiers inherent to the base type or implicits added through Eldritch currency.

Since Item sells for much more to vendors count as an implicit and the fossil adds its implicit on top of any other existing implicits, vaaling the item has a chance to remove the Item sells for much more to vendors implicit instead of other implicit modifiers. This can be used to have both a desirable implicit (e.g. Unset RingUnset RingRequires Level 5Has 1 Socket's socket) and a corruption implicit.

The implicit itself has several weighted variations, with one chosen at random when the fossil is applied to the item. Using an Orb of HorizonsOrb of HorizonsStack Size: 20Reforges a map item as another of the same tierRight click this item then left click a map to apply it. on a map with Item sells for much more to vendors will randomize the vendor price offered by NPC vendors when being sold. Because of this, the vendor offer in the sell screen displays as a generic hidden item to prevent exploits by deterministically rerolling for the good outcomes.^{(before version 3.16.1, certain outcomes provided multiple stacks of currency, allowing them to be discerned even when hidden)}

The vendor price from Gilded Fossils takes priority over Item sells for X Crucible passive tree nodes and prevents the use of vendor recipes to "clean" fractured base types.

Version history

Version	Changes
3.16.1	Gilded Fossil modifiers that had multiple sell price outcomes now instead have a single possible outcome. This is to solve a problem where some outcomes of a Gilded Fossil modifier can be previewed in the Vendor window, and visibly change in quantity when the item is modified using currency that changes an item's base type.
3.10.1g	When vendoring an item that has had a Gilded Fossil applied to it, the sell value is now hidden.
3.4.3c	Using a Fractured FossilFractured FossilStack Size: 10Creates a split copy Cannot be used to split Influenced, Enchanted, Fractured, or Synthesised itemsPlace in a Resonator to influence item crafting. 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.
3.4.0	Introduced to the game.
