How do I get more colored Gems?
Build up Discoveries
The best way to earn Fire, Nature, and Water Gems in Cascade is to build up your Discoveries.
Discoveries are located throughout the map. Once built, they'll slowly earn colored Gems.
Each Discovery gives out all types of the gems you can currently collect.
Upgraded Discoveries give a finite number of Special Gems; the higher the level, the more gems you can harvest.
You can always earn extra Gems by replaying through levels!
