I truly don't think there is a need to talk before and after because you can't do that during each battle with the exception of base 1. You can start base 1 then "after" talk or "before" talk then do base 1 ... talk ... base 2 ... talk ... base 3 ... talk ... base 4 ... talk ... base 5 ... talk ... base 6 ... talk. So before and after can no happen because you can't start a base and leave to talk unless you die. Before and after is always after the previous base only by default. Or before the fight by default but not both for each base, its just how you look at it.
An example is this: You beat all six bases without dying, and follow the rule: "You have to talk to the Duke of Ghor before starting the bases and after each base!" The word before and after makes the rule invalid if I went through base 1 through 6 while talking to the Duke before each battle. I can't satisfy the before and after since its a single event only while rule is written as multiple events or the rule would look like this:
[talk ... base1 ... talk] ... [talk ... base2 ... talk] <---- each base rule of before and after
"You have to talk to the Duke of Ghor before starting
the bases and after each base!" Since the 3rd line changes occur before base 6, the rule works.
Please let me know your thoughts...
