Once you reach level(Maplestory powerleveling) 70, your finally qualified to become a Dragon Knight. First, you have to go to Orbis, head down Orbis tower and arrive in El Nath. At El Nath, find the highest portal and enter it. There should be 3 people, 1 who is named Tylus. You must once again return to Dances of Balrog in Perion after doing so. If you do not remember where he is located by now. We pity you and will not give you his location.
Anyway, talk to him and he makes you go into the dungeon. Keep going in until you reach the 24 hour store, whose map name is Ant Tunnel Park. Look around for the Door of Dimension, which should bring you to "The Path of the Gliterring Crystal." You must walk to the end until you see the dark warrior(Maple Story Meso), and when you defeat him you aquire a Black Charm. Return to Dances with Balrog and give him the Black Charm. He will take it, and in return give you a Necklace of Strength which you have to give to Tylus back in El Nath. Hope you like this guide to Maplestory.
