Uber Uber Elder Farm

Overview

The Uber Uber Elder is the hardest version of the Elder and Shaper double fight. You face both bosses at once in an area level 85 instance where monsters take 70% less damage. Almost all of the money sits in one drop, so this is a strategy you run for a long stretch or not at all.

What you are farming it for:

• Sublime Vision — the exclusive drop, and about three quarters of the profit on its own.
• Decaying Reliquary Key and Curio of Decay — the other two drops only this tier gives.
• Impresence — the full power two curse variant, guaranteed to the uber tier's pool.
• Orb of Dominance and Watcher's Eye — the steady income between Sublime Visions.

Setup

• Four Decaying Fragments per run. That is the entire cost.
• Nothing else is consumed — no map, no scarab, no second fragment set.

The Encounter

Both bosses fight you together. Only one can be hurt at a time, and that swaps every 25% of the vulnerable one's health. The Shaper can be killed; the Elder plays a death cutscene instead.

What kills people:

• The Shaper's vortex balls — every ball that touches you leaves a freezing pool for the rest of the fight. Walk them to the arena edge or you run out of floor.
• The Shaper's beam — three seconds of fire, cold and lightning that ends most builds. It does not track you, so step sideways.
• The Shaper's cold balls — two extra ones here, penetrating 40% cold resistance.
• The Elder's Ring of Death — stay inside the inner ring until it explodes. This tier casts three in a row.
• Teleport slams — both bosses vanish and land on top of you. Keep moving.
• The adds — kill Madness Propagators before they leave a degen. Volatile Anomalies cannot be hit, so pop them in a corner.

What to bring:

• Capped elemental resistances, with extra maximum cold resistance for the balls and icicles.
• 5,000 or more combined life and energy shield, plus real recovery.
• A movement skill, for the beam and both slams.
• Far more damage than a normal pinnacle fight needs. The 70% less damage taken modifier is what fails builds that clear regular Uber Elder comfortably.

How These Numbers Were Calculated

Nobody ran 100 of these and wrote down the loot. The sample is modelled from the wiki's published drop rates and we estimate that the encounter takes 3 minutes:

• A 1.5% chance counts as 1.5 drops across 100 kills, and a 46% pool item counts 46 times.
• Expenses are one run's four Decaying Fragments multiplied by the same 100 runs.
• Every item is priced at its current market value, so the totals move with the market.

Where the model can be wrong:

• The rates are estimates. The page's sample is 429 observations across 3.24.0 to 3.27.0 and 1,738 across 3.28.0 to 3.29.0, and it warns that actual rates vary.
• A short session looks nothing like it. Ten or twenty kills is far too few for these percentages to mean anything.
• One-off drops are excluded. The Decayed Voidstone drops on the first kill only, so counting it 100 times would invent profit that is not there.

The real caveat is concentration. Sublime Vision is about 74% of modelled profit on its own at a 1.5% drop chance, which is roughly one every 67 kills, and adding the Orb of Dominance puts 85% of the profit in two items. Going 100 kills without a Sublime Vision is normal and does not mean anything is broken, but it does mean a short run of this strategy usually loses money. Judge it over hundreds of kills or not at all.
