Observe lets you skip a step in hopes that the little "Normal" becomes "Good" or "Excellent". "Good" gives you 150% of the quality and "Excellent" gives you 400%. (I think)

Also, I would level up Culinarian to 15 to get thier cross class ability that doesn't use CP. (Names escape me) Then you can keep your condition up and spam that skill and get as close to 100% as you can.
