Quest walkthrough
- Use the Castigator's Keep Beacon in Outskirts of Mammon and enter the keep's central stone tower.
- Speak to Egon and choose the option to feed him your stored Gloom.
- Deposit Gloom in chunks (5,000 to 10,000 increments) and watch for his dialogue and physical appearance to warp.
- Continue depositing until Egon collapses and dies, unlocking the silver trophy 'Feed Me'.
- Loot his remains immediately to recover roughly double your deposited Gloom (up to 40,000) plus Egon's Stone.
Important note
Source consensus: PowerPyx and NerdsChalk report 10,000 to 20,000 Gloom invested yields a 2x return on death. Complete this quest before triggering Send Ova, as starting NG+ permanently closes his tower.
