2 Iron Axe
Only Intelligence (at the time of capturing the resource, Knowledge is 14, then 16 due to boots).
It is theoretically impossible to capture the resource in 6 days. In 7 days, you can try if you rush through vampires, but then you need a tactic. There was no tactic; the Archmage was needed for the first turn. It is difficult to find a hero who would be given Tactics, Wisdom, Earth, Air, etc., so that he would develop well in Knowledge and Attack, but not in Defense, so that he could capture the resource on the first day. And all of this at the same time. Otherwise, it is impossible to defeat the resource in 7 days. As a result, I played as Dess.
