# Resource System

![](/files/Zrmg7MUqpRm5Kq6s5pwQ)

***A resource system, at its most basic level, allows a player to "buy" goods, improvements, or other game perks***. Fundamentally, resources are utilized when the player builds towers and sends forces against the adversary. But how does the user obtain resources? The user obtains them by killing enemies in a traditional tower defense game. ***Sindia's resource system consists of two different types of resources: energy and float crystal.*** Energy may be used to launch cards onto the battlefield, whereas float crystal can be used to improve or synthesize more complex cards like crafting cards, runes, equipment, and leveling talents. It can also be used to purchase in-game objects, as well as forge and upgrade artifacts.
