The starting area is very large, with lots of money and resources.
In the first week, I reached level 6 in the castle, and in the third week, I reached level 5 in magic (Implosion, Resurrect).
On 1-4-4, I reached the opponent's capital and took it by storm, albeit with some difficulty. Aldegir almost held out (lightning spell for 325 damage and a lot of mana), but after the assault, only remnants of my army remained, but the opponent's main hero was killed.
Overall, I didn't expect such resistance; the chances were almost equal.
I confirm that 1 wyvern + 1 demon + 17 magi successfully stormed my castle.
There's such a thing as an unfavorable opponent... Rhox is exactly that for me... the game seems fine, but 5 losses... or maybe it's just a pattern =)
... anyway, I'll demand a rematch until I win.
