There are some ways to make serious money later in the game if you find yourself a bit low. You can put your Skills to good use by buying Items, raising their value and re-selling them. This can be done by using Enchant, GM Fire Aura, and GM Vampiric Weapon. You can also mix Potions for sale, the more complex the better.
Win your first game of Arcomage in all known Taverns. Go on a Bounty Hunt or win at the Arena. The harder the challenge the more you'll earn.
Finally, there are three trading triangles that you can run, in whole or in part. The first two can be worked fairly quickly with the help of Town Portal. All can be run more quickly with Lloyd's Beacon. You only need capital, pack space and Spell Points to get started. There are a few restrictions that we'll let you discover for yourself, and prices vary daily, but that shouldn't be a big concern.
