The Ancient Castle is one of the three magic stone dungeons, and part of the Main Quest. It has a Danger Level of 17. The first four levels of the dungeon are randomized, and unlike the Tower of Fire, it lacks an overall theme for enemies or maps, so expect regular Danger Level 17 monsters. On the last floor players will confront the lord of the Ancient Castle accompanied by diverse chess-type enemies. Bringing potions, rods and spell stocks of silence is also recommended.
