Training Guide up to LV 50

LV 1-10
At this lvl you cannot really do much especially on Maple Island.

LV 10-20
By this lvl you have probably have made your first job advancement. I recommend you do the quests that your leader gives you. When you are done with that do HPQ (henesys party quest) until lvl 20. Also if you prefer to train on monsters remember to train on Friday because that is 2x EXP day. It is also very good to do the special agent quests.

LV 20-30
Do KPQ (Kerning City Party Quest) as it gives decent prizes and good EXP.

LV 30-50
At this lvl do CPQ (Carnival Party Quest at Orbis or Kerning City) this PQ gives good EXP. Also if you are looking for good mesos go to the Bigger Ben in NLC (New Leaf City) press up on the teddy bear and then keep pressing up until you get inside. When you are inside keep going down until you get to a guy named John Baricade and do his quests.

I will continue this to LV 100 when I get more experienced and lvl up to at least LV 80.
