The currency of Hallownest, made from fossilised shells of various forms. Can be traded for goods or used as toll in various old mechanisms.


Used to buy goods from merchants or to pay tolls for Stag Stations, Trams, and Benches. Also used to pay the Nailsmith to upgrade The Knight's Nail.

Geo‍3000 is also required to obtain the Vessel Fragment from the fountain in Ancient Basin.

How to Acquire

Geo can be gained in several different ways:

While the Gathering Swarm Charm is equipped, a small swarm will gather any dropped Geo for the player, except those fallen in water or acid. Fragile Greed increases the amount of Geo enemies drop.

Keeping Relics to sell to Lemm when Geo is needed is particularly useful because unlike Geo, these items are not lost upon death.

In Steel Soul mode, Rancid Eggs can be sold to Steel Soul Jinn for Geo.

Good Sources of Geo


One-time Sources

  • Gorgeous Husk in the City of Tears drops Geo‍420 upon death (Geo‍672 with Fragile Greed equipped)
  • In Kingdom's Edge, there is a hidden passage accessible by breaking a wall in a room with a Great Hopper and a lot of spike pits. At the very bottom of it is largest Geo deposit in the game, rewarding Geo‍420. This value is not increased by Fragile Greed.
