I have read quite a great deal of threads on crafing and quick leveling them on this site, but i have yet to see any of the following. These images are not my own creations, but I thought they might help.
which is from

I dont remember where i got this one but there is a lot of versions out there.
The compass works simple. You face the direction depending on the crystal you are using and what you want. If you were using an Earth Crystal you would face SE when attempthing the synth for HQ/Skillups, but for Success rate you would face directly south. Hope this helps everyone.
