If you're looking for a high-end farming strategy in Path of Exile 2 that can generate serious returns in POE 2 Currency, Abyss farming for Ancient Bones is one of the most profitable options currently available, if you can handle it. This method focuses on Ancient Jawbones and Ancient Ribs, two highly valuable desecrated currency items that drop exclusively from Abyss chests. While the strategy is straightforward in concept, it comes with a steep difficulty requirement that makes it inaccessible for most players.

This is not a gimmick farm, nor does it rely on obscure mob interactions or time-specific tricks. Instead, it revolves around stacking rarity and reward modifiers to dramatically increase chest output from Abyss content. If you're geared enough to survive the punishment, the rewards can be enormous.
A Quick Disclaimer
Before diving into the mechanics, it's important to be realistic. This Abyss Ancient Bone farm requires extremely strong gear. Roughly 80–90% of the player base will struggle to complete it effectively because it relies on the "increased difficulty and rewards per closed pit" modifier. This modifier massively boosts enemy damage and survivability, especially toward the end of Overrun maps, where monsters can easily one-shot undergeared characters.
Because of this, the farm is best suited for softcore players with optimized builds. Hardcore players are strongly advised to avoid it entirely.
Debunking the "Gold Scaling" Myth
There has been speculation that increasing gold values on maps somehow increases Ancient Bone drops. Extensive testing has proven this theory completely false. Runs were conducted with no gold, moderate gold, and high gold modifiers, and the results were effectively identical when rarity and pit difficulty modifiers were not present.
The takeaway is simple: gold does not influence Ancient Bone drops. Chest rarity and Abyss reward modifiers do.
Farming Results and Profit Breakdown
Using an optimized setup across 50 maps, the following drops were recorded:
5 Omens of Light
26 Omens of Abyssal Echo
5 Ancient Jawbones
5 Ancient Ribs
34 Preserved Jawbones
2 Preserved Craniums
4 Preserved Collar Bones
At current market prices, this translated to approximately 1.16 Divines per 50 maps, placing it very close to the profitability of a standard Omen of Light farm. However, unlike un-identified hearts, Ancient Bones offer consistent returns with far less variance, making this a stable source of POE 2 Currency.
That said, Omen of Light farming still has a higher profit ceiling due to rare drops like Heart of the Well, which can sell for mirrors. The tradeoff is cost, Omen tablets are expensive, while Abyss tablets used in this method are relatively cheap.
