How to Acquire

Geo Chest

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 acid. Fragile Greed (as well as its unbreakable variant) 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.

A great early source of Geo is the Husk Guards in Forgotten Crossroads. Many enemies in the City of Tears, especially Great Husk Sentries, as well as Hoppers and Great Hopper in Kingdom's Edge, are also great sources of Geo.

The fastest ways to farm Geo later in the game are to continuously complete the Trial of the Conqueror or to farm Dirtcarvers and Carver Hatchers in the Failed Tramway with Fragile Greed or Unbreakable Greed equipped.

One-time Major 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 the largest Geo deposit in the game, rewarding Geo420. This value is not increased by Fragile Greed.
  • Millibelle the Thief will return roughly 1.5x what is deposited in her shell, when in the Pleasure House. See here for more details on this process.



  • The maximum capacity for Geo is 9,999,999.
