The Bent Pyramid is a monument type in Pharaoh.
The bent pyramid is built in a similar way to the stepped pyramid: peasants clear the earth until they expose bedrock, cut grooves and fill them with water to level the site, fill the grooves with rubble, and then cut a tomb. Stonemasons then lay stone moved there by peasants from storage yards (said storage yards must have at least four blocks of stone). Every subsequent level requires a carpenter to build a ramp so that the stones can be lifted to higher levels.
However, there are some dissimilarities to the stepped pyramid. The outermost layer of the pyramid requires limestone instead of plain stone. While the lowest levels require more plain stone than limestone, the ratio shifts towards limestone towards the higher levels, to the point that only limestone is used for the last couple of layers. In addition, after laying all of the blocks, stone masons then cut and polish the outer layer of the pyramid until it is smooth.
In the campaign, the Bent Pyramid is only available in South Dahshur.
