Discussion of level 8 monsters.

Yes, the topic can be closed now....
Arguments ;) Fortress – the castle is designed for attack, and creatures can really help! They significantly reduce the enemy's defense, and with the Double Strike skill, and heroes usually have a fast and good attack growth... also, in Heroes, there are banners of the commander... you can give it to creatures and set it to reduce defense... and if they are lucky enough to strike with a double strike..... then... I think I don't need to explain what will happen :)
Swamp (or whatever it's called). The Hydra becomes a relatively fast unit for it; it's not countered, and it hits everything around, especially good against the AI, which often clusters together :) Sulfur Breath... also deals significant damage... and another plus – there was an option in the game to upgrade some creatures to a third level. So, Serpent Nests and Dragon Caves are often scattered on the map... you can capture them and upgrade them in the castle to Elite Hydras, and there will be a lot of them :)
