King Mummies appear as random encounters in the Citadel of Trials and the Mirage Tower, appearing alongside other Mummies in the castle, and along with Cockatrices and Pyrolisks in the Tower. They also appear at the Waterfall Cavern, along with mummies and Cockatrices/Pyrolisks, depending on the encounter. When they appear as random encounters, they appear with Mummies, but they also guard the inside of a room in the Waterfall Cavern, appearing with Cockatrices and Pyrolisks.
Overall, they are not hard to defeat. If they appear in groups of mummies, use a Fire or Diaga spell to kill them quickly. If they appear with Birds, the Cockatrices should be your primary target, as they can Petrify your characters. Once the avian enemies are defeated, a powerful elemental spell should be used to defeat all remaining King Mummies.
[view·edit·purge]A mummy is a human or animal whose skin and organs have been preserved by either intentional or incidental exposure to chemicals, extreme cold (ice mummies), very low humidity, or lack of air when bodies are submerged in bogs, so that the recovered body will not decay further if kept in cool and dry conditions.
