How Do you become a ranger in maple story

Once you are level 70, go in El nath. Go to a big house in that town and talk to Rene. She will tell you to go to Athena Pierce (in Henesys). Go back to Victoria and talk to her. She will tell you kill her clone and that the door of dimension is in Sleepywood dungeon V. Go through the door and in there, you'll have to kill Athena Pierce within 20 minutes. Once you kill her, pick up the Black Charm and leave through the sparkling crystal. Go back to Athena and she'll give you the necklace of strength. Go back to Rene and she will see the necklace. Then she'll ask you to go answer some questions at the Holy stone. The stone is located in the Holy grounds in the snowfield. Make sure you have a refined Dark Crystal with you. You'll need one to answer the questions (5). They are randomly picked from a selection. If you fail a question, you'll need to pay another refined Dark Crystal to try again. Once you answered them all, you'll get the necklace of wisdom. Go back to Rene and she'll make you a ranger.
If you get confused on where a portal or entrance is located, just go on the Internet and search up some Maplestory maps.
