ro which you can get easily, if you level up quickly. Where to level up you may ask me, well I will tell you, AGI knights are hard to level up at first but you may get easy to lvl up at the later stage due to the high DEX and high AGI you have. I will start from level 12 as this is the level where you change job to swordman.
12-20: You could stay with Rockers or move on to Peco-Pecos. Stay on with pecos to level 30 also can. A tank is possible for faster rate.
21-30: You can choose to level in Culvert until you get RO Zeny better or go to Smokie Forest or Byalan or stay on pecos till lv 30.
31-40: Fight goblins if you have a good party. Or for a cheaper choice go to Byalan instead. It is best to solo on poporings until you can solo orc village on the orcs.
41-50: You will feel the slowing of your progress since you do not get much expience anymore. You can try Draniliars in Coal Mines or in orc dungen till you change job if you are really patient.
51-60: The Boring Years as I would like to call it. RO Zeny Continute level in orc dungen till change job. After that proceed to level 2 for more experience.
61-70: Spnix level 2 or maybe on pryamid on the minorous if you have enough AGI and flee rate.
71-80: Try on coal mine level 3 till a certain level and proceed to turtle dungen level 1. Your AGI must reach 99 in order to train on turtle island.
81+: Anywhere as long as you can handle, Ragnarok Zeny turtle island is one of the place or GH or magma.
