Scrolls are extremely important for game play, and it's better to start collecting them as soon as you can.
- The main way to earn Scrolls is through Studying at study buildings such as the Library and Observatory. Studying any subject earns Scrolls after the duration is over and the Scrolls are collected.
- Upgrading your study buildings can offer more Scrolls, but the durations are often longer, meaning that studying short-term subjects over the same period could earn your more Scrolls ultimately.
- Some Chests in battles reward Scrolls.
- Scrolls are sometimes given as rewards for completing quests.
You can also buy Scrolls with Rubies from the Shop or the "Get More Scrolls" popup.
