The Ancient Gates are located in the Shaman Caves and must be opened to proceed through the caves during the Legends' Quest. The first gate features a complex locking mechanic and must be opened using a lockpick (note: a strange old lockpick will not work), requiring 50 Thieving. The second gate is heavily constructed, being made from cast-iron, 50 Strength is required to push it open. The third gate located in the room with the Carved rocks can only be opened by casting any Charge Orb spell on it while having an uncharged orb in the inventory, resulting in the player automatically jumping through it.
