I cannot locate the recipe for the Ring of Insight. Anyone know where I can buy the recipe? I have checked the krokotopia and olde towne recipe vendors as well as any other vendor I can find.
The recipe for the Ring of Insight can be found at Eudora Tangletree in the Olde Commons. If she does't have it listed, than you have already purchased it.
You can check your list of purchased recipes by hitting the "J" key.
If the recipe isn't available from the Krok that gave you the quest, check to see that you haven't already purchased it. That would be the only reason he would not have it.
