Enemy ship, in the cloud of fog ...

As soon as she reaches the top edge of the fog and begins to poke her head out of it, Seraphina tries to circle the mast -- if necessary -- to ensure she's approaching from behind the preacher as she continues up, knowing she'll no longer have any actual cover to rely upon should he happen to look directly down at the mast and that not even a housecat can look very innocuous scaling the mast of a ship in the midst of a pitched battle.
As an aside, is that fire illusion still going? If so, unless she's entitled to (and makes) whatever save it allows, Seraphina will ... *sigh* ... switch to her Flame's Blessing stance as a swift action if she's about to come into contact with it. After all, just because I know it's an illusion doesn't mean she automatically does, but she did at least know from the beginning that she could disregard fire for the most part.
