Ok.

How does this STUPID failing system work?

I just spent 4k on a frigging summon avatar and failed it, and now I have to start from scratch to get it again.
I have 17 int. I have level 10 wisdom. I should be able to learn it.

I just don't get this stupid thing, and it really pisses me off that I spent so much time just to fail it.

I really would like to not fail again. So how does it work?
