Age of Empires Online

The Large Pyramid blueprint can be obtained by completing the "Quell the Masses!" (King Narmer) quest chain in your city.

The Large Step Pyramid is acquired as a reward for the quest "Vizier's Doom" quest, which is also an achievement, so see the breakdown for the quest there.

The Small Step Pyramid blueprint is a rare treasure chest reward (I actually found mine on the last "Quell the Masses!" quest, so in reflection: check all of those maps after you win as the enemies will respawn)

The required materials are:

• 5 Concrete Blocks
• 4 Precision Tools
• 3 Giza Limestone
