Please tell me how to make it so that building a Grail changes the weekly effects (using scripts or a patch for Heroes of Might and Magic V - anything works).
For example, I want to make it like in Heroes of Might and Magic III: when Inferno builds a Grail, instead of getting bonuses to magic and other things, each week would be a "demon week."
I think I need to look at the weekly effect in the files (like with the astrologer option).
