Wizard Runes

[Castigate]

Diving through the inventories of Commons and Freeport merchants is a really good way of picking up research materials. Even if they aren't displaying a rune they may still have it, you just need to be willing to buyout items that they only have a limited number of and sell them back over and over again to find out what else they have. Obviously if you're on a tight budget it isn't an ideal solution, but if you just want to get the job done that may help.
