What i would suggest is putting more than the minimum required in all those paths, most especially Air. The main thing about Mirror Image is that it creates 1 image for each level of air you have, and as far as i can tell there is an equal chance for each image to be attacked. It only goes away when they land a solid hit on the real image (i believe a solid hit, not just an attempt). So with 4-5 in Air you get 4-5 images as opposed to only 2, with correspondingly better odds for avoiding the hit. Also with higher level's in the paths you accumulate less fatigue which can be important to the non-undead SC's. I usually avoid fire and focus on air water and earth. 4-5 air, 2 water, 3 earth minimum. As soon as possible i try to get them a luck pendant which helps out a bunch for its cost/low requirements. I'm alot more willing to sacrifice scales then you evidently are though, so you might not be able to afford everything im suggesting.
