Corroded Fossil is a fossil type.

• Is sometimes sold by Niko the Mad for 10 000 Azurite

Spawn Weight Multipliers

Using this fossil multiplies the spawn weights of all modifiers with "elemental" tags by 0, modifiers with both "physical" and "ailment" tags by 10, and modifiers with both "chaos" and "ailment" tags by 10.

All mod with "cold"/"fire"/"lightning" tags also have "elemental" tags, thus Corroded Fossil affects those mods as well.

Version history

Version	Changes
3.12.0	Item modifier tags have been entirely reworked with a goal in mind of consistency and simplicity. These changes have negligible impacts to the odds of various modifiers appearing on rare items naturally, but may have impacts to the results of certain crafting methods. A list of all modifiers and their associated tags can be found here. As a result of the above changes, several fossil descriptions have changed slightly. (In Manifesto) Corroded Fossils and now affect mods with both the Physical and Ailment or Chaos and Ailment tags rather than the Bleeding and Poison tags. The Bleeding and Poison tags are no longer used.
3.10.0	Fossils can no longer craft any prefix or suffix mods that cannot be obtained elsewhere, with the exception of those granted by Faceted, Bloodstained and Hollow Fossils. Implicit modifiers (such as the one which changes an item's vendor sell price) remain. The following mods have been relocated, while all others can no longer be obtained:
3.4.0	Introduced to the game.
