No, you don't.
Mones is free to play.
At game's beginning, you will be given 3 heroes to start the adventure.
During the game journey, you will have a chance to acquire heroes and equipment which are NFTs through winning stages.
As, each troop has a minimum of 1 hero and a maximum of 5 heroes, 3 heroes is a good start.
If you prefer pay-to-win, we will grant your wish. You can acquire strong heroes & equipment through in-game summons or buying on Mones Marketplace.
