All castles in Heroes 3.

Monsters are killed quite normally. And they have nothing to boast about except -80 to enemy defense:)

These are the words of someone who has no idea about Heroes 3...:cool:
Only Titans can compete with monsters, and they easily defeat everyone else:)

Added after 3 minutes

And they also defeat Archangels! Monsters appear at most after 3 weeks... or even much earlier!

You're exaggerating, is it something to be proud of that "monsters appear in the third week"? With a good map layout and a large number of resources and money, Angels can be built in the first week! And even with resources, monsters cannot be built before the end of the second week:)
