[HMM V OFF TOURNAMENT] "Wise Hero"

Share your secret on how to complete this map in one hour.

Even I, playing Heroes of Might and Magic V for the first time, didn't finish the map in one hour... =) Although, it's possible that the map is very easy for him, and in one hour, he implemented all the plans he had =D ;)
Well, let's get started...
My very modest result:
Experience - let's skip that for now =)
Kaspar's level - 27
Initial skills: 13, 24, 27, 21 (total - 85, I think)
Oil - 32
^_^
Unfortunately, I couldn't do more (( Now I know that I could do much more, and by a significant margin! =)
