Unfinished adventures

I gather you get XP for the amount of enemies killed if the adventure finishes uncompleted. How much per unit? Or how does it work, please?

I don't really like adventures to be honest (have done a dozen or so. I get spells of interest) but still like to see the level go up sometimes, and I'm only a thousand or so points away from levelling up. I've got Sons of the Veld running (NEVER going to complete that in the near future. I just thought I'd have a look). How many camps would I have to take out to get that 1000 pts?

Advice appreciated :)

Simulators tell you the XP of enemies

Was after a general rule, which I presume exists as general knowledge. Can deduce it I think though. Should get that 100 point easily enough by the looks.
