PoE Fossil Crafting Guide: PoE Blight 3.8 – Perfect Fossil Crafting Quality & Drop Location, on Unique

You can use Fossils crafting special Delve modifiers. By socketing PoE fossils into resonators to modify the crafting behavior in specific ways.

  • Fossils + Resonator = Crafting Mods

1. PoE Resonators

Delve Stackable Socketable Currency or resonators is a new item class introduced in the delve league. They are currency items that allow crafting rare items similar to Orb of Alchemy Orb of Alchemy or Chaos Orb Chaos Orb, but can be socketed with Fossils in order to change their crafting behavior. Fossils cannot be unsocketed once all the resonator sockets are filled.

WARNING: Despite the similar wording to chaos orbs, using a fossil + resonator on an item with a meta-crafting mod (such as “prefixes cannot be changed” or “cannot roll caster mods”) will ignore that mod and overwrite existing prefixes and suffixes ignoring any restrictions.

There is an older variant of this item class available Delve Socketable Currency which will be converted to the new item class upon pickup. The old variant is no longer obtainable.

For PoE 3.8, Resonators can now stack. They have a stack size of 10 in normal Stash Tabs and the inventory, and the Primitive Resonators can stack to 5000 in the Currency Tab.

3. PoE Fossils Crafting Example – Perfect Fossil

Perfect Fossil Perfect 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.

Effect: Improved Quality. Sets quality randomly from 15 to 30%. It can be used to improve the quality of a weapon, armour, flask, map, and strongbox. It cannot be applied on gems.

Quality can be applied to most equipment other than amulets, rings, belts, quivers and jewels, as well as strongboxes. Quality is normally capped at 20%. However, there are certain crafting methods that can increase quality beyond that, including:

  • Beastcrafting recipe for “Corrupt an item with 30% Quality”
  • A resonator with Perfect Fossil Perfect Fossil socketed, increasing quality up to 30%
  • Immortal Syndicate safehouse with Hillock stationed

Additionally, certain Veiled modifiers add Quality as part of explicit mods. This bonus quality does not count against the 20% quality an item is normally allowed to have, even if the veiled modifier is added before using currency to upgrade the item.

On Unique

If you want a unique item with 30% quality:

  • 1. Using many Perfect Fossil Perfect Fossil to craft a 30% quality item.
  • 2. Applying Orb of Scouring Orb of Scouring to change the item into a normal item.
  • 3. Using thousands of Orb of Chance Orb of Chance to chance it.

This will cost lots of currency and time. It is worth it if you can get the base 6l much cheaper than the unique 6l.
