QE Invoker Build
In my opinion, you have to understand the way
Invoker plays (particulaly QE) and why you max/get what you get for a reason, and then you will do a lot better. General points, you want double
Forge Spirits as early as possible, so 4 
Quas 4 
Exort 1 
Invoke is the earliest, and then at level 10 
Wex for all your spells
