Discussion of level 8 monsters.

I like the ghost creatures because, firstly, they can pass through fortifications, which gives a big advantage when attacking a castle, unless there are flying creatures, and also because of their health.

Their advantage also lies in the fact that they completely ignore the enemy's defense (meaning they always see 0 defense for any monster). In Heroes of Might and Magic V, they can also attack twice. But in terms of characteristics (attack, defense, speed, unique abilities, such as the ability to resurrect, turn to stone, spit acid, return, etc.), they are inferior to many other creatures of their level.
Here, no matter how you look at it, Super Archons remain the strongest...
