This Guide is More so For Elfs Since I have no Knowledge for other races but will get to the other race money makers.

As an Elf you Get many Advantages.

1.Big town With very own Dungeon that can Lvl you past 20.
2.Many Quests are available to you.
3.Quite easy to make money as an Elf.

This Guide is mainly on how to make money at low lvls in elf village. So lets get to the point.

1st easy money making quest

Hunt The Orcs: lvl 6
1. Speak with Sentinel Rayjien at the southwestern village exit. He will ask to to kill Kaboo Orcs and collect Orc Amulets and Orc's Necklaces.
2. Hunt Kaboo Orcs (lvl 6 passive), Kaboo Orc Grunts (lvl 7 passive), and Kaboo Orc Archers (lvl 8 passive) that drop Orc Amulets, and Kaboo Orc Fighters (lvl 10 aggro), Kaboo Orc Fighter Sub Leaders (lvl 11 passive) and Kaboo Orc Fighter Leaders (lvl 12 passive) that drop Orc's Necklaces.
3. Return to Sentinel Rayjien at any time and turn in the amulets for 5a and the necklaces for 15a.

Note:You can come back with as many badges and may keep doing this quest over and over.

A very good Money Maker for once you are strong enough for the Back of the Elven Fortress.

Destroy Plague Carriers:lvl 18 quest
1. Talk to Master Ellenia in the main building of the Elven Village.
2. Hunt Sukar Wererats (lvl 18 passive) and Sukar Wererat Leaders (lvl 19 aggressive) which drop Wererat's Fangs, and their boss Varool Foulclaw (lvl 20 passive) who sometimes drops a Varool Foulclaw's Fang. Once you get a Varool Foulclaw's Fang, you must return to Master Ellenia, as you will NOT get another until you restart the quest.
3. Return to Master Ellenia at any time and turn in the Wererat's Fangs for 60a and the Varool Foulclaw's Fang for 10,000a.

Sorry If I skipped alot of Lvls but Other good Quests are the Spores Quest which is Quick and Easy and Also the Lirein quest.

Note: The Lirein Quest is Advised for Wizards with an Area of Effect spell Or else the quest wont be affective.
If you do have an Area of Effect Spell Gather Many Lireins at one time Since you can Outrun this slow mob and Continously hit the Mob till there dead.
