I'm new to Adventure Paths and am unclear about how much experience points to give PCs. For example, if they have an encounter which the Adventure Path says is worth 400 XP, does that mean each PC gets 400 XP or (in the case where there's 4 PCs) does that mean they each get 125 XP? Additionally the Adventure Path says that PCs "should be 2nd level when they start...". How sure can I be that the Adventure Path is written in such away to insure that this will be the case? Thanks to those who can clear up these questions for this Adventure Path novice.
