The Pyramid Has 5 stages to build with items crafted in the Archaeologist Tent. I completed the first 3 stages quickly but using the Torch Recipe… Easy materials to gain and the recipe is instant.
Once you complete stage 5, you will see this message: you can wait 24 hours, and then stage 1 will repeat. You can leave your Pyramid alone, or periodically do stage 1 for extra bonuses.
Once you finish, every time will only be stage 1
