The strongest castle in Heroes of Might and Magic IV.

YES, if Life + Chaos, it's definitely a powerful combination... in general, most combinations improve the rating of a particular faction... but in this topic, when we talk about the strongest castle, we mean a castle with magic and all its perks, without any crossbreeding. i.e., the strength of the castle with its initial parameters and at its maximum, without crossbreeding with other magic or factions:) (figuratively).... so in this topic, I'm only talking about the area highlighted in red.
