Players can unlock the Gems in Frontier Justice feature by constructing the Founder’s Monument inside their Township. Gems come with corresponding attributes. Compose them to get higher level Gems with better attributes.
How to get Gems?
Gems can only be obtained from opening Gem Strongboxes, which can be purchased with Gold, found when slaying Critters, or obtained in the Smuggler’s Den.
Inset Gems into the slots in the Founder’s Monument to receive the corresponding attributes. Gems come in six colors: red, orange, yellow, green, blue, and purple. The slots come in seven different colors: red, orange, yellow, green, blue, purple, and multi-colored. Multi-colored slots can accept Gems of any color, while the other six colored slots can only accept Gems of the corresponding color (red for red, blue for blue, and so on). Once Gems have been inset, you will need to use Cash if you wish to remove them.
