Level 1-10 goes quite easily as a archer level up by killing monsters a higher level then you. Once you reach level 10 you will be much stronger than other classes. Use this to your advantage kill high level mobs and move onto lumberjacks and 3 tailed foxes fairly soon after once you can kill them without dying. Do not bother with parties. They will slow you down at this point. It is much faster to level by yourself.
An archer can level without getting hit once by killing slow moving mobs. However if you are not short on money tank the hits as it will increase your leveling speed faster.
At level 20~ move onto bandits. They are extremely slow moving. This allows you to kill them before you are able to tank them. Once you get to level 25. Move deeper into bandit camp. You will see a bandit that has a no weapon and just his fist. This is the boss bandit despite his lack of name above its head.
By attacking this 3 times then running off until it stops following you and then ranging it at a distance until it notices you will gain 10x more exp than a normal mob and kill it in approx 3 times that of a normal mob. Making this your leveling method all the way to 35 (2nd job change.) The best method to level on these is to rotate between the 2 off them One at north section and one at the middle section.
Congrats on 2nd job change.
If you chose order than your leveling location is at poachers till 40. If you chose chaos then it's at runaway spears.
Once you reach level 40 parties become the best leveling method and you will be leveling in parties of 8 players all the way till end game. Say goodbye to soloing however soloing is still best for money when you're getting low on it.
A ideal party is that with 6 archers and 2 healers. Or in some cases a few AOE blades provided their equipment s high enough for some decent damage. A lot of people make the mistake of leveling on high level mobs 1 because they assume they will be partying with higher level players and 2 because better xp and they don't comprehend the time it takes to kill the mobs. Don't rush to tigers as soon as your 5x and can do damage on them. In fact the best exp to lvl 55 is in the jungle in a good spawned location of spear maidens leveling with other 5x plus characters.
By following this pary method and the level to player gap throughout your levellings you will reach end game at your fastest potential.
