Nett's Pyramid is a party quest located in the Nihal Desert region, and accessible via the Dimension Mirror between the levels 80 and 109. There are 2 modes, Normal (level 80-89) and Hard (level 90-109), and you must have 4 people in your party. The objective of Nett's Pyramid is to protect the Obelisk on the left side of the map from monsters that spawn in large swarms. The Obelisk has 20 life points, and each monster that reaches it takes away 1 life point (except Pharaoh Yetis, which take away 2 and Pharaoh Mummies, which take away 5). Once the life reaches 0, the PQ will be over.
