P.S. Could you elaborate on the cows?

Are you referring to the gorgons? I mean the ones near the Oasis... The ones in the south are just strays... They probably graze there... :) This is a remnant from one of the earlier map versions, which was later changed, but I decided not to remove them because, theoretically, for an extra 2500, they can be obtained... And what if someone decides to fight dragons to level up?
Then the gorgons would be very useful...

In short, there are countless ways to play this map! And that's what makes it interesting! :)

And yet, how did Fure take the blade + gold from the Castle at the start?

In theory, this is impossible... In any case, I placed the objects so that the Blade would not be available to anyone without special training.
