As mentioned previously , the Crystal Tower consists of four levels , each of which is considerably unique . These levels are not large ; in fact , they are not any greater in size than the initial Prison where the Eternal Champion starts their quest . The First Level is simple to pass — upon entering , the door to the Second Level will be nearly exactly to the north of the entrance . While making the way to the Second Level among the white walls of Crystal Tower , the enemies of this first area will be Trolls . In addition to their quite decent strength , these creatures have the ability to regenerate without using magic . Trolls will always heal their wounds and attack again . It is not necessary to explore the east area of the First Level to complete the quest . The Second Level is more complicated ; in this area the demonic creatures Homonculi will start to appear ; against these beings , the Resist Shock effect will be greatly useful . Upon entering this area , the Eternal Champion will be on a long corridor . The door to the Third Level stands exactly to the east of the entrance , and the fastest way to reach it is to go right on the corridor , then go right again , enter another corridor , enter the first door in sign , and again enter the door on the other side of the room . Then go on the left and follow the way up to north without going back . However , if the Eternal Champion possess the spell Passwall , it is possible to break the slender wall which divides the corridor and the door to the Third Level . The Third Level is unique , and perhaps one of the most interesting areas in the Main Quest as a whole . This level is a bestiary which includes many creatures and information about them . The Bestiary contains Rats , Wolves and their snowy variant , Hell Hounds , Homunculi , the three elemental Golems , Trolls , and one Fire Daemon — however they are locked in cages and fighting is unnecessary , with the exception of the Trolls and the Fire Daemon . The door to the Fourth Level is exactly south of the entrance , but to reach it will be necessary to find a Diamond Key . The key can be looted from a random Troll defeated on the same level . Alternatively , it can be found on the west - most cage , which is connected to the underground passages . Use these subterranean ways to reach the cage and take the key . It should be noted , however , that Trolls will appear in the corridors . Before going to the last area , it is possible to fight and collect experience points from some of the most dangerous creatures who appear in the Main Quest : there are three Medusas ( 40000 points ) on the south corridor and one Iron Golem ( 25000 points ) on the big room located in the northwest . The entrance to the Fourth Level is located on the southeast room , which is surrounded by unbreakable walls , but the door which opens the room can be unlocked using the Diamond Key .

It uses fireballs to attack from long range and at close range attacks using a pickaxe . After defeating the creature , the Eternal Champion can enter the fourth and final area . The Fourth Level does not require as much caution as the previous levels , as the only enemies encountered in this levels are Snow Wolves and Ice Golems , with the exception of a few Wraiths who appear in the rooms . The Fifth Piece of the Staff of Chaos remains on a large room surrounded by unbreakable walls which occupy the southwest space of the Level , and the only door to this room is locked by a riddle . There is a Steel Key on a little room close the entrance ; while this key is not the only way to reach the piece of the Staff of Chaos , it will unlock a faster way to do so . Upon reaching the door to the room where the Fifth Piece remains , a riddle will be given to gain access : The answer is " Egg . " The door will open , however upon approaching the Fifth Piece , two Wraiths will appear . After taking the Staff ' s Piece , the Eternal Champion must then get out of the Crystal Tower . Ambush .
