The Desert Idol, or most commonly known as the Gambling Totem, is a small totem that can be found in a Desert chunk through secret non-collidable blocks. The totem's eyes are light objects, emitting light.
Mechanics[]
By interacting with the Idol, it will either dispense a random ore and temporarily change eye colors to blue, or will "bust" and dispense nothing, signified by red eyes and the player will take damage. The Idol has a cool-down time of 20 seconds. If you attempt to get a ore during the cooldown, it's eyes will flash black and red.
It is good practice to mark the spot where the Idol is located once found, so that it can be located again more easily.
Ore drops include coal, iron, sapphire, diamond, steel, stardust and ruby.
