Gems is an in-game currency you can use to buy ranks, boosts, keys and more for you and your friends, it's a cross-server currency that you can spend on any of the TMM servers.
The shops/NPCs to spend gems on survival are in /spawn on the right.
We've made sure all players get 10 gems right away when you log in for the first time after this post! <3
Gems can be earned or donated for, our goal is to make sure that dedicated players who play daily can get nice rewards and those who want can buy gems through donations.
Check how to get gems by clicking here, or typing /getgems in-game.
