If you play a good party in Baldur's Gate 2, it is very likely that the vampiers of Amn become your enemies. That means that you can't go out and buy a bottle of milk in Amn without being attacked by a bunch of vampires, and they make very short work of your heroes unless they have "Protection from Undead". Also, the vampires are immune to normal weapons. That means that your archers and slingers have to switch to +2 shots/arrows everytime they take a walk in Amn, and that you group your heroes together to cast the Protection spell on them all at once. The spell lasts for an inconveniently short time too, so you'll have to do this pretty often. If you don't have mapped a lot of Protection from Undead castings on your casters, you also have to go to sleep a lot to regain the spells you've used up. That's just how Baldur's Gate 2 is.
Thanks for warning me.
