The Golden Altar is a rarely generated altar that can be found in the Stone layer once the player has 40 in their inventory. There are 4 per small world, 6 per medium world and 8 per large world. They can be broken with a hammer with 55% hammer power or higher. Explosives have no effect on them. When they are generated, a message will appear: "The world's gold has solidified into a point..."
When broken, the Midas miniboss will spawn and the altar will drop 10-20 Gold Bars and 30-40 Gold Ore.
