Vampires tend to take vampire bat form and stay that way, unless/until there's a closed door they want to pass in which case they change to fog cloud form. Those shifted forms are weak, so pet vampires tend not to attack other monsters, and if they don't take damage, they won't change to vampire form. So, when comparing relative strength of self and foe while deciding whether to attack another monster, treat their own strength in weak form as if in vampire form, making them be more aggressive. Hostile vampires shouldn't need any comparable change. They don't use relative strengths when deciding whether to attack something.
