Ya so this is my mess up. I need help to fix. Tried asking before and was told to Go to Nameless. Dunno how that helps me fix my current issue, but ya, I need help fixing my skills. Not training area.

By the way did I mention I suck with this class? Took me 21 tried to pass Wizard test. So if you know different builds please use them You can post the build as if I were 99/50 cause I'll most likely be trying to get to that number. Help please.
