I'll answer you - it's not here! :(
I was also sure that such an artifact would definitely be included... But alas... :)
If this is possible, is it allowed to use them?
And the hint about the two main battles is not a discussion. It's obvious when you look at the map. But if I tell you how to defeat 5x2=10 Phoenixes without losses, that would be a discussion...
Let's say I say that they can be defeated by a hundred Dark Knights without losses :D I don't mean using cheats – they are prohibited. Is this a discussion? Or, let's say, you tell me how to defeat them with one Fairy, indicating how much mana is needed for such a battle :) if it is even possible?
In general, I highly doubt battles with legions with one Fairy. Theoretically, they are possible, but what about in practice? Let's say 1000 upgraded Dwarves. Health: 1000*20=20000
Well, I don't know, let's say the Fairy takes away 2 points per hit. And this hit is made in 1 second.
Although it will take 5 times longer for this hit (human factor + computer turn)
To defeat everyone, it takes: 20000/2=10000 seconds; But in reality, it takes 5 times longer
10000*5 sec=50000 sec; 50000/60 = approximately 833 minutes; 833/60 = approximately 14 hours. CONTINUOUSLY. If we consider that there are 24 hours in a day and you can spend 4-5 hours on the game (which is a good time), then this battle will take about three days.
Maybe I messed up the calculations, check it. How many such battles can be held in a tournament that lasts a month? I'm not talking about this tournament. The question is purely rhetorical.
