well I can tell you you are going to lvl up fast here compared to interlude midrate, because there is something called vitality and nevits and it boosts your exp by a lot.
level to 10 in your starter town, then move to Stronghold 3 in the Kamael village and go to level 20 there. Change you class and equip D-grade gear.
After than you can move to sacrifice necropolis and go all the way to 80+ farming in appropriate necros/catacombs(less adena this way) or stick to the regular hunting zones. Opening your map and use the hunting zones tab to sort by level, this is what I do.
Playing on an autofarm server you will be max level in no time.
