Nature Structures

1 Phoenix – allows you to easily clear levels 1-2, and with the support of your heroes, you can handle certain units on level 3.
2 Phoenixes – you can clear almost any level from 1 to 3.
3 Phoenixes – you can clear any level from 1 to 3.
4 Phoenixes – you can defeat some level 4 monsters.
*With the right tactics, of course, against level 4, you need at least 3-3-3-0.

1 Dread Knight – you can defeat some level 1 and 2 monsters. It's better to be wary of Gnomes and stay away from Golems.
2 Dread Knights – the same as with one. The potential has increased slightly.
3 Dread Knights – now you can do something, you can defeat some level 3 monsters. We are still afraid of Golems. We don't even look at Thunderbirds!
4 Dread Knights – first of all, how did you manage to gather 4 Dread Knights! Now I can kill 3 monsters! Although level 4 monsters can still beat me. I'm still very afraid of Thunderbirds.
*We never look at Champions of the Deep! We can't defeat them anyway.
-To make them solo everyone (with the support of heroes, of course), you need 7-8 Dread Knights. And even in this case, the Thunderbirds will peck at us, the Phoenixes will burn us well, and we will have to kill the Angels at least 1.5 times, and we may run out of mana.
-Dread Knights are good in combination with a decent strike force (Phoenixes and Griffins), because then 1-3 Dread Knights (1+1+1) are enough to simply keep the enemy confused, thereby allowing the strike force not to be afraid of attacks from all sides. When Dread Knights are out of mana, they become a level 3 unit, and not the most outstanding one (except for HP).
