I sent the save file. I improved the result by 2 days. I think that if the difference is 7 days from IronAxe, that would be good. :D
Now all that's left is to wait for the results and :smile11:.
It's a pity that I couldn't find out how and where to use the "graveyard" technology.
P.S. Good luck to all participants:D

For example, you can use the "graveyard" technology to replenish mana reserves, but this only applies to demons, and does not affect heroes and units-mages that do not have combat spells. Or, in one turn, transfer the hero's "graveyard" to the castle using units lined up in a chain. This is useful for "softening" a neutral unit with a hero, pulling the "graveyard" out from under the unit, transferring it to the castle, and then attacking with an army with a live hero at the head, or continuing to "finish off" the neutral army (for example, for resources or an artifact).
In general, there are so many different tricks for using the "graveyard" that probably no post would be enough!
