## Basic Resources

### Gold

The starting resource for the game, Gold is used to level up buildings, buy upgrades, acquire Diamond research, and later on use with Midaeum.

### Diamonds

Diamonds are the standard thing you see in every idle game out there. They increase your gold production by 1% for each one you have. They are generated as blessed diamonds and turned into regular diamonds upon doing a glory reset.

The formula for the total diamonds is:
