The Quest for Truth

You really seem to be having good luck with the Orcs; they usually visit your castle around weeks 2-3 in "Hero" difficulty.

on Grand difficulty, the castle and whoever is inside will hardly survive the onslaught (there's too little meat)... I highly doubt anyone can defend themselves in this mode, and it won't be possible to control the situation much (heroes have a maximum of 60/80 mana), and the Mentor is still invulnerable. My tactic is to use distracting "roaches" on the water (fortunately, there are plenty of logs floating around - although the castle suffers). Sandro has almost caught up with Markel in development (the enlightened chainmail was very useful). It's very difficult on Grand difficulty. Let's continue playing.
