The Kalphite Lair is a dungeon located in the desert region of Gielinor in the game RuneScape. It is home to various types of Kalphites, which are insect-like creatures that players can combat for experience and loot. The lair is accessible through a tunnel entrance found in the Kalphite Queen area. Inside the lair, players can encounter different Kalphite variants, including the weaker Kalphite Workers and the more powerful Kalphite Guardians. The dungeon is often visited for training combat skills and for the chance to fight the Kalphite Queen, a challenging boss that drops valuable items.
