Max Slash Storm, you'll need it. Also max Fatal Blow.
Once you hit 3rd job, max out Flash Jump and save your points for 3rd+job.
At level 70 put all your points into Flying Assaulter, maxing it first, then max Bloody Storm. These are your main training moves until 200. Once you've finished that, get Mirror Image (more attacks/damage), then Upper Stab. Go back to 3rd+ job, max both Flash Bang and Tornado Spin (TS first, I would say), then max Advanced Dark Sight. I believe at this point you should be level 11x or so. If you haven't already, put your remaining points into Nimble Body.
With any remaining SP, just throw them into Owl Spirit. Either way you won't be using it much.
