Some Suggestions for Leveling 15-20 in Lineage2
Level (Lineage 2 gold) 15-20: This is the first point where things get tricky. One good quest that any race can run is in DE starter village. Local quests become few and far between while things like Grim Collector in Giran are not anywhere near as lucrative as they once were. Talk to the Dwarf Collette in the Warehouse, deliver his letter to Gludio, and then deliver the letter you receive there to Gludin. The quest takes about 20 mins.
When you run along the roads, less if you know some safe shortcuts and the two runs together pay over 20,000 adena. Despite the fact that it is far less lucrative than it once was, Grim Collector is still not a bad way to spend an afternoon. Good money at this level for a one-time quest in Lineage2. If you do not use NG shots, the free novice shots, however, are very helpful; you can easily turn 20-25,000 adena in a couple hours. Nowadays it is better to sell the bones and everything to Samed and not bother having complete skeletons made.
Do not overlook the Level (Lineage 2 money) 15 Pet Quests from Martin in Gludin. It is expensive for those who have to use the boat or Gatekeeper, but for Elves or Dark Elves it's a couple hours of easy leveling. Selling the wolf collar should bring you around 25-35k. You could also choose to keep the wolf. They are a pain to level in today's Aden, but quite fun for anyone who is not a power leveler solely intent on hitting 52 as early as possible.
