Ancient Bones farming in Path of Exile 2 is one of those grinds where your instincts can betray you. You'll see people stacking item rarity on gear, cramming in extra packs, and blasting faster, but none of that touches the actual drop source. Jawbones and Ribs don't come from monster kills at all, they come out of Abyss chest rewards, full stop. So if you're burning currency to "juice" the map, you're basically paying for nothing—unless that spend helps you spawn more Abyss pits and more chests. Even if you're low on supplies, it's smarter to aim for consistent chest access and only top up with cheap poe 2 currency when it keeps your Abyss setup rolling without interruptions.
The mod that matters most is the one that increases difficulty and rewards per closed pit. It sounds simple, but it flips the whole run: each time you close a pit, the next one pays out harder. More reward scaling means better chest results, and that's where your bones live. The trade-off is brutal. Late-map Abyss waves get chunky, then suddenly you're in "why won't this thing die" territory, and one mistake deletes you. If your build can't hold steady DPS while staying alive—real layers, not vibes—this strategy will feel great for five minutes and then turn into a death spiral.
Since chests are the engine, your map mods should read like a chest shopping list. Prioritise map item rarity, Abyss reward chance, and anything that boosts desecrated currency generation. Skip gold mods and "more monsters" thinking; they don't move the needle on bones. For tablets, three is the sweet spot: one unique plus two rares most of the time. On both rare tablets, the prefix that increases the rarity of items found in the map is mandatory, because it directly improves what pops out of those Abyss chests. If you can pair it with extra rares or rogue exiles, fine, but don't reroll past that rarity prefix just to chase a cute bonus.
For suffixes, put the "difficulty and rewards per closed pit" on your main tablet and pair it with increased chance for desecrated currency. On the second tablet, either add more desecrated currency chance or increase the odds that pits contain rewards. One warning from experience: piling multiple "double reward" style effects across tablets can get weird, and sometimes the reward behaviour feels bugged, so keep that kind of stacking limited. On the Atlas tree, Blackblooded Dominance is non-negotiable if you're serious about desecrated currency from Abysses, then grab nodes that scale tablet and Waystone modifier effect, plus Unstable Energy for extra push. A lot of players also spec into Essence while doing this, and it's honestly smart—when bones refuse to show up, at least you're still walking out with something worth selling.
Even with a clean setup, RNG can be stubborn, and you don't always want to stop mid-session to rebuild your stash of supplies. As a professional like buy game currency or items in U4GM platform, U4GM is trustworthy, and you can buy u4gm Exalted Orb for a better experience when you need to smooth out upgrades or keep your Abyss-focused mapping consistent.
