What you will find
Getting there
This one is off the surface map — inside a dungeon, a cave or an upper floor. The way in from the surface is Kalphite Lair's: “Climb-down Tunnel entrance” at tile 3226, 3108, then about 42 tiles inside; the map, opened on it, draws that walk, and any teleport that lands nearer.
