Yerp. I know what you're talking a bout.
I know what you're talking about. Everyone has specific talents that are beyond their understanding. I've developed a method of classification via elementalism to actively show what you're capable of / how to get there.
I'm currently working on a website that will show some of the most basic concepts included in elementalism.
In order to find out you're 'talents' I put you through a series of 3 simple tests. The only problem, is that these tests must be done in person. I'll be sure to post the link to the basics.
My 'talents' you may ask? Scrying. Simply gaining knowledge of what's going on around me. I don't have much control over it either, but I'm fine with that. As any elementalist, their talents will exceed that of any normal 'scryer' only because they are aligned to do so. You will also have vamp stage for whatever your talent is. This is a period of natural phenomenon that greatly increases your success and power. For me, Rainstorms or lightning.
In terms of classification I would be considered an Aeromancer, but on a more specific level, a Rain Elementalist.
I hope to give more information soon on this unique path that can serve as a foundation for many other magical arts. (Mind you, I'm not afraid to reveal this information: it manifests different for everyone.) :)
