The Mummy Cat is an enemy found in the Great Pyramid. They are the most numerous enemies in the dungeon.
Mummy Cats hop around slowly, stopping to extend their claws and swipe at the player. This makes them very easy to avoid. However, they are quite difficult to take down with physical blows due to their very high defense. If the player wants to destroy them instead of avoid them, alchemy is the way to go.
The Mummy Cats leave a decent amount of experience and Jewels, but their vulnerability to alchemy making it the best way to fight them makes them impractical for grinding, even in Antiqua.
