When you reach level 120, you can get a new job advancement. This is the last one you will need and it is also the most powerful for any class. Here’s what you need to know about individual progress for each class:
White Knights become Paladins, Dragon Knights become Dark Knights, and Crusaders become Heroes. Priests become bishops, wizards become archmages, rangers become bowmasters, and snipers become marksmen. The hermits become lords of the night and the main bandits become shaders.
In all cases, to get the fourth Maple Story job, you need to talk to the NPC you spoke with to get the third job trailer. Then you will be told who to meet to get the fourth job. For archers, the NPC is Legor. For Warriors, it’s Harmonia. For magicians, his name is Gritto, and for thieves, he is Hellin. All NPCs in the fourth job will ask you to obtain two items: a Heroic Star and a Heroic Pentagon. Griffey and Manon drop them, but you can also get them by giving a Secret Spell Letter scroll to Chief Tatamo in Leafre. You can buy said scroll on the 44th floor of the Eos Tower from someone named Vega. It costs 10 million mesos.
Take Heroic Star and Heroic Pentagon to your fourth job advancement NPC and they will give you a new skill book. Talk to him again and he will give you your new job. You will be rewarded with 3 skill points and 5 skill points as well. To get the most of your fourth job skills, you need to do missions.
