Making money

Dwarves are the only class with a crafting skill, and a lot of the items you find while hunting can be used as materials in Dwarven recipes. Often, Dwarves will often pay more for ore, coal, twigs, stems, and so forth than you can get by selling to NPC traders.

Ask (or look) around for item prices in other cities. Something that sells for 40K on Talking Island can net a nice profit in another town. It might be worth going into the export business — buy something in one town, sell it in another.

Look for repeatable quests that award you adena. It may be tedious to kill the same 50 monsters over and over, but it's a reliable way to build your assets.

If you're able to enchant items, you can make money. But enchant only the top item of your grade.

You can't enchant non-graded weapons.

You can safely enchant an item three times. After that, it has a chance of blowing up.

Enchant Scrolls are dropped by mobs and can increase P.Def (armor), P.Atk (weapon), or M.Def (jewelry). Scrolls of Enchant Armor work on armor and jewelry, while Enchant Weapon works on weapons. But, the scroll must be the appropriate grade for the item (C, D, etc.).
