The strongest castle in Heroes of Might and Magic IV.

I don't know, but a REAL weapon against Haven is life:D First: Amulets and blessings that will make it so that 7 Crusaders can take on 2 Titans:) We need to create an artifact that grants immunity to spell removal, and then Haven will be at a disadvantage. (By the way, 2 Angels can defeat 2 Titans without any losses. And the Angels are reborn:D)
