Localization setting

Path of Exile 2 introduces unique bone-themed currency drops from Abyss encounters. Among them, the Gnawed Collarbone, Preserved Collarbone, and Ancient Collarbone are used to desecrate rare jewelry—specifically Amulets, Rings, and Belts. These items mirror the rib currency used on armour, but focus entirely on accessory slots.

Currency Overview

Each collarbone tier corresponds to a progression milestone and drop level, meaning stronger versions appear later in the game.

All three serve the same role: they socket a hidden “Desecrated Modifier” into your accessory, waiting to be revealed later in the game.

If you’re looking to speed up your progress without grinding every Abyss encounter, the quickest option is to grab what you need from trusted marketplaces. You’ll find Cheap Path of Exile 2 Currency for sale, making it easy to stack Collarbone items and keep your Amulets, Rings, and Belts rolling with powerful desecrated modifiers.

How Desecration Works

Applying the Currency
Use the Collarbone on a rare Amulet, Ring, or Belt. This adds a “Desecrated Modifier,” which occupies a prefix or suffix slot even while hidden.

Revealing the Modifier
Take the desecrated item to the Well of Souls in Act 2. Here, the hidden modifier is revealed, and you'll be offered one of three choices.

Modifier Pool

• Some modifiers are standard, functioning like regular affixes.
• In endgame, some revealed modifiers may be exclusive and unavailable through natural crafting or drops.
• Because the modifier already reserves a slot, it guarantees one revealed affix but limits future crafting flexibility.

Strategy & Endgame Implications

• Progression Use: Early on, Collarbone items are a solid way to sneak in extra power on accessories.
• Crafting Depth: Desecrated affixes can block prefixes/suffixes, shaping the way you approach meta-crafting.
• Endgame Value: Ancient Collarbones become especially valuable since late-game exclusive modifiers can significantly impact builds.

If you're targeting high-value affixes, always save Preserved or Ancient Collarbones for higher item levels, ensuring the modifier pool has the best possible outcomes.
