If you find yourself short on Geo for upgrades or Charms, certain areas are more efficient for farming:

- Forgotten Crossroads (Infected): After the Infection spreads, many enemies here become stronger and drop more Geo.
- Deepnest (Fungified Husks): The Fungified Husks near the Fungal Wastes entrance drop a decent amount of Geo and are relatively easy to defeat.
- Colosseum of Fools: The trials, especially the Trial of the Conqueror, offer significant Geo rewards upon completion. This is a late-game option.
- Relic Selling: Regularly visit Relic Seeker Lemm in the City of Tears to sell any relics you've found.
Equip the Gathering Swarm Charm to automatically collect Geo and save time.
