About Antitoxin Workshop

Priority: Medium

The Antitoxin Workshop produces antitoxin, a resource required to gather from plague-infected tiles on the world map. Higher levels increase antitoxin production rate and storage, directly expanding the number of plague zones you can safely gather from.

Upgrade Tips

  • 1Upgrading Antitoxin Workshop is essential before pushing into higher-tier plague zones.
  • 2A low antitoxin reserve limits your gathering marches — keep production ahead of demand.
  • 3Antitoxin Workshop upgrades pair well with Herb Garden upgrades since herbs are used in antitoxin production.
