Party Quest Exp?

[Gerik]

Do any of the PQ have however much exp they give?

Is there a reason they're left blank? ^^
Or is it the lack of information?

The exp you get from a PQ depends on how many members are in the party and how many kills you did of the total amount of mons required.
The more members in a party the more exp you get.
The more kills you get the more exp you get, so its wise to find someone who stands afk for you to get the bext exp for each run.
