If you use the "Easy gold" glitch and amass a fortune in gold, you can basically get unlimited experience. When you save the life of the Arl of Redcliffe, a soldier of his will appear in your party's camp. There will be a box for donating to the army. Enter the screen, and the first option is to donate 30 gold. You can do this as many times as desired and gain a good amount of experience from each donation. If you just keep pressing A then X repeatedly, you will be quickly donating large sums of gold, skipping through the dialog screens, and earning a lot of experience. If you run low on gold, repeat the "Easy gold" glitch again at the merchant in your camp. Note: Be careful with this. Enemies will also level as you do. If you get too high of a level and do not have the correct equipment, you can be quickly defeated.
