Intro Dialogue[]
Introduction | HELLO! Welcome to Rich-ards grand Gem Exchange! The grandest place to spend your Gems! |
Trade in your "worthless" Gems to unlock more progress on the exchange pathway. | |
As you get higher in tiers, the price goes up, but so does the reward! | |
Do you have what it takes to finish the exchange and claim the ultimate reward? Gem Pegasus! |
Rewards[]

Note: Every week, the rewards can be optionally reset in order to avoid mass purchasing of the Gem Pegasus and Gem Alina items. The aforementioned items also increase in price every time you spend Gems on them; Gem Alina's price will double, and Gem Pegasus' will increase by 5,000,000,000,000 (5T) Gems, in order to similarly avoid mass spending.
