Abyss
Area contains Abysses
An Abyss is a crack that runs: follow it, kill what climbs out, and it keeps opening until it either closes or drops you into the Abyssal Depths. What it pays out in is bone — and bone is the only way to put a Desecrated modifier on an item.

Common questions
How does Abyss crafting work in Path of Exile 2?
You use a bone on a Rare item of the matching kind, which adds an unrevealed Desecrated modifier. You then reveal it at the Well of Souls, choosing one of three offered modifiers. Omens set before the reveal narrow what you are offered.
What is the difference between Gnawed, Preserved and Ancient bones?
Grade. Gnawed bones only work on items of item level 64 and below, which makes them the campaign-tier version. Preserved bones work on any item level. Ancient bones work on any item level and additionally guarantee a minimum modifier level of 40.
Who are Ulaman, Amanamu and Kurgal?
The three Liches whose names every Desecrated modifier carries. Each has an Omen that forces the reveal into that Lich's pool: Omen of the Sovereign for Ulaman, Omen of the Liege for Amanamu, Omen of the Blackblooded for Kurgal.
Are there Abyss Jewels in Path of Exile 2?
No. Abyss Jewels and the Stygian Vise were the first game's version of this mechanic; Path of Exile 2 replaced them entirely with bone desecration, which puts the Abyss modifiers directly onto ordinary Rare gear instead of into a special socket.
