You fly at quarter speed and can glide over terrain and other obstacles at normal speed. However, you cannot move more than a couple feet above the ground. You fall at the rate of 30 feet per round (30 feet per 5 seconds).
Healing can be used to damage you. If the creature providing you healing specifies that they are doing so "for damage" then you roll your largesthit die and take that much holymagic damage instead of the normal healing effect. This does not consume any of your hit dice.
You know what the natural weather will be like in the next 24 hours in your location (clear, rainy, snowy, and so on). You also predict the weather conditions, natural or not, for the next 1 hour. This only gives you the type of weather, not the exact intensity of it. However, you can tell if the intensity will be more or less severe than it is currently and broadly how much so (for example, "much hotter" or "a little more violent"). Finally, you know whether the weather at your location is natural or unnatural.
