Description: Will-o'-the-wisp are small ghostly lights that float above the ground. It is said to resemble a flickering lantern and can cause travellers to stray off safe paths in an attempt to follow it. They don’t really have a physical form, and the only way to see them is the constant fire particles coming from them.
The Will-o'-the-wisp, like the bat, serves no real purpose and exists only for atmospheric purposes. They wander about aimlessly, emitting light levels similar to that of a torch. If you pass through the mob you will be set on fire for a short time, but they are otherwise harmless. You can use them as a source of ectoplasm or, if you trap one, it can be a pretty nifty bit of lighting.
