Sarcophagus

The Sarcophagus is a special block that generates inside pyramids. Inside lays a wealth of treasure and an ancient pharaoh. The loot inside of it cannot be obtained until you have slain the pharaoh. Once the pharaoh is killed you can also break the sarcophagus and take it for decoration.

When attempting to open the Sarcophagus you will be greeted with a message about the pharaoh inside rolling over. You must ignite a Royal Torch on each of the four Chiseled Limestone Blocks surrounding them and then attempt to open it to awaken them. Once the pharaoh is defeated you can then loot the sarcophagus and break it.
