Yeah, I do. The cost should go down as the skill levels, and since one of my main stats is WIS, I'm going to end up having MP to burn. As I am right now, I should still be able to get through a fight with both that skill and Zandaka on at the same time. Not only that, but the idea of not having to worry about finding new weapons, and instead using one that has unlimited use and can get stronger is too tempting to pass up
