After Vome kills Fass to begin the Vome cycle on the Cambion Drift, small zones of orange energy will appear in various locations. Entering a zone will cover the edges of the screen in orange sludge. Multiple deposits of Fass Residue will spawn inside each zone and can be destroyed to acquire 1 Fass Residue each.
Blueprints Requiring Fass Residue
- Amount yielded is not affected by Resource Boosters or .
- Resource deposits are not marked (e.g. ).
- 6-12 Wyrm Residue, depending on squad size, (either Fass Residue or Vome Residue) are needed to activate the bait machine in the first stage of the Isolation Vault bounty. Existing Residue will despawn, and new Residue will respawn for the players to collect.
- They can be traded at Father in exchange for Father Tokens in quantities of 6 to 12. Curiously, Father will never ask for Residue in Token bundles that reward two or fewer tokens.
