Amber is the primary currency in Against the Storm, used for trading with caravans, buying blueprints, and sometimes resolving glade events. It's primarily acquired by selling surplus goods at the Trading Post or as rewards from orders and glade events. Efficient trading is crucial for managing your economy.
Trade Goods are specific items often produced in specialized buildings (e.g., Pigment, Scrolls) that have high Amber value when sold to caravans. Focusing on producing these goods can be a viable strategy for generating significant income, allowing you to purchase any missing resources or blueprints you need to progress.
