Abyssal Trove Cranium Farming

Overview

This is an Abyss strategy built around one thing: opening as many Abyssal Troves per map as possible. Preserved Craniums and the ancient bones drop from those chests, so the whole setup is aimed at making every abyss pit in the map produce a reward and then squeezing extra value out of each chest that appears. The creator of the strategy calls it "the everything farm" because a single map returns Omens of Light, Omens of Abyssal Echoes, ancient bones and Kulemak's Invitations all at once.

Why it works

Chest contents scale with rarity on the map and the tablets, not with character rarity. Two Abyss tablets carrying Abyss pits in maps are twice as likely to have rewards guarantee a reward in every pit, and increased chance for desecrated currency from abysses is the second required line. A third tablet, Unforeseen Consequences, pushes the abyss count up. Because the Abyssal Depths are unaffected by tablet mods, the Omen of Light half of the farm is driven entirely by the waystone instead.

Setup

The low-effort waystone is a six-modded T15 using Chaotic Effectiveness and Chaotic Omen Quantity. The high-effort version is a corrupted T15/T16 with 60%+ increased monster rarity and 40%+ increased item rarity — item rarity feeds the chests, monster rarity feeds the Omens of Light, and splitting between them is what makes the farm cheap to sustain. Weight it toward item rarity if Craniums are the goal.

Tablets ran at roughly five chaos each for the two Abyss tablets and three for Unforeseen Consequences. Bring Cryptic Keys: an Abyssal Trove strongbox opened with one pays out twice, and that is where the Craniums come from.

On the Atlas, take Jado as the master. Parcel Translations adds explicit modifiers to tablets, Mysterious Gifts restocks Cryptic Keys from unique monsters, and Trove Seekers doubles rare chests — the node that matters most here. Take the Omens and Amanamu passives so the Abyssal Depths contribute Omens of Light.

On city maps a Delirium tablet is worth adding: more monster modifiers means more Omens of Light, plus Grand Mirrors and delirium splinters on top. Wildwood wisps stack with the four tablets, but not with 200% delirium.

Note that this page tracks the pathing setup only — the waystone plus the three tablets above. The city-map variant is not tracked here, so neither its extra tablet costs nor its extra returns appear in the numbers on this page.

What to expect

The recorded sample is 35 maps. One known quirk: on heavily overrun maps not every pit spawns a reward despite the guarantee, which appears to be a bug rather than a setup mistake. The sample also excludes raw divines and chaos, preserved ribs and collarbones, and the Kulemak's Invitations were banked rather than run — invitations are generally worth less than the ancient bones they contain, so running them should add to the total.

Watch the source

The linked video is worth the time before running this. It walks through the exact waystone mod rolls, the tablet lines in priority order and the Atlas tree placement, and it shows the trade searches used to find each piece. Those details — and the routing decisions that get a map cleared in six minutes rather than ten — are what separate the creator's numbers from a first attempt at copying them.
