Ruby Formation
Ruby Formation supplies Rubies for building and upgrading the village.
Unlocking it
Talk to 
Corrin in 
Crystal Desert and accept their offer to bring this resource to the village. It then appears in Resources at the 
Upgrade Well once you meet its Well-level requirement.
Gathering
Mine the formation with a Pickaxe. Direct a duck to the resource, or let residents choose their own work. Each successful collection adds 
Rubies to your supplies. Improving the 
Pickaxe makes gathering more effective.
Building and recovery
You can build additional ruby formations from Upgrade Well. Leave room around it for working ducks. When depleted, it recovers after two minutes and can be harvested again.
Building
Use the Upgrade Well to build this item. Leave its work area and entrances accessible. The costs below are starting costs; additional copies can cost more.
