Jebus Cross - 2.

Naturally, in an already generated map, there will be fixed monsters, right?

Yeah, of course.
At first, I was puzzled... how is it possible... I have a level 6 creature guarding, and my opponent has a level 2 creature, for example, and I was sure that my opponent should have the same level and number of creatures guarding the resource, but no...
So, it's normal if one player's resource guard is much easier than another player's resource guard of the same level.
