Zorath, Vile Assembled Farm

Overview

Zorath, Vile Assembled is the pinnacle boss of the Abyss mechanic, fought in The Lightless Hollow. Every kill drops one guaranteed unique from a pool of six, and four of those are rare, valuable Historic Abyss jewels.

Setup

One run consumes one each of the four Zorath's Eye fragments, placed into Zorath's head to start the encounter:

• Zorath's Eye of Malevolence — from Amanamu, Liege of the Lightless (~20%).
• Zorath's Eye of Authority — from Ulaman, Sovereign of the Well (~20%).
• Zorath's Eye of the Inevitable — from Kurgal, the Blackblooded (~50%).
• Zorath's Eye of the Endless — from Catarina, Master of Undeath (~50%).

The Lightless Hollow is reached directly from the Atlas. One run takes about three and a half minutes end to end. That is the house estimate (a 3:00 kill plus half a minute for travel and loading the eyes), not a measured time, and it assumes all four eyes are already in hand.

How These Numbers Were Calculated

• The method. These figures are a synthetic 100-kill sample built from published drop rates, not recorded runs. A 10% unique is counted ten times and a 40% unique forty times. Expenses are one run's four eyes times the same 100 runs. The hourly figure spreads the net total over a modelled 3.5 minutes per run.
• The rates are estimates. The drop table comes from version 3.29.0 with a sample of 311 kills, and the wiki marks the content as new and possibly incomplete. Results over a short run of kills will differ.
• Excluded. Reclaimed Malevolence, which is crafted from the four Historic jewels rather than dropped, and the Phylacteric Crystal's Bloodline unlock are not counted.

Almost all of the modelled profit sits in the four 10% jewels, and Festering Vengeance alone carries over 40% of it. Subsume the Source and Spinesnatch drop most often but are worth very little. A run of kills that yields only those two is the normal case, not a sign the strategy is broken.
