This spell causes a misty vapor fo arise around the druid. It persists in this locale for 4 rounds per level of experience of the druid casting the spell, and it reduces visibility of any sort (including infravision) to 2’ to 8’ (2d4). The area of effect is a cubic progression based on the druid’s level of experience, a 1” cube at Ist level, a 2” cube at 2nd level, a 3” cube at 3rd level, and so on. Underground, the height of the vapor is restricted to 1”, although the length and breadth of the cloud is not so limited. A strong wind will cut the duration of an obscurement spell by 75%.
