The seventh stage of the "Van Kanigem" tournament.

I completed the map in 4 days, but with a hero's stat total of 10. I knew that a stat total of 13 was needed and knew how to achieve it (an artifact + 2 points north of the castle, where there's also a gazebo and a chest, plus a chest to the left, and so on).
This results in the hero reaching level five (4500 + experience), and the artifacts provide a bonus of 3 to the stats – a total of 13, as required.
But I didn't replay it...
