Egon Quest Guide: Feed the High Lord of Mammon

Updated Sep 1, 2026 | Castigator's Keep · Reward: "Feed Me" achievement
🎯 TL;DR: Find Egon in the central tower of Castigator's Keep and choose to feed him Gloom. Keep feeding him in chunks until his quest concludes and he dies — unlocking the "Feed Me" achievement. Bring extra Gloom, because the exact threshold isn't settled.

1. Where to Find Egon

2. The Feeding

Deposit Gloom in chunks and watch his dialogue and state change. There's no single published total you can trust.

⚠️ Source conflict on the cost: one launch guide reports a 10,000-Gloom threshold, while another describes paying 20,000 and recovering 40,000. We deliberately don't state either as fact — bring a big reserve and watch Egon's reactions rather than counting to a number.

Continue feeding until Egon dies and the "Feed Me" achievement unlocks. Loot the quest result from the tower before you leave.

🎯 Bottom line: "Bring spare Gloom, feed him in chunks, end when he dies." The exact cost is a moving target, but the Feed Me achievement is the reward for indulging the High Lord's strange hunger.
