Version history

 * 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) 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.
 * (Not in patch note) Above poison tag change also affects Aberrant Fossil.


 * 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:
 * On Boots: +2 to level of socketed Chaos Gems (now from Hunter's Influence)
 * Belt: Increased Chaos Damage (now from Hunter's Influence)
 * Rings: Fire/Cold/Lightning/Physical/Chaos leech modifiers can now exclusively be found from special elemental Delve encounters.
 * Weapons: Chance for Poison/Bleeding inflicted with this weapon to deal more damage (now found from Elder's Influence)


 * Introduced to the game.
