I think Midnight Oil's slow effect is a bit too powerful at area denial for such a low cost. With Int 9 at level 3 or w/e my Witch could basically halt any melee assaults with near-impunity (costs 3 AP with these stats).
Add to this the fact that you can set it alight for added environmental effects/damage and it's basically extremely devastating.
Ex: If you set a patch of oil on fire you can essentially chain smoke and burning along the ground by linking Midnight oils, causing a wall of death easily formed in a single turn. This is likely a function of fire being too powerful combined with the low AP cost of Midnight Oil, but so be it. I suggest a reduction in burning damage and a 1 point AP cost increase on Midnight Oil.
