Our guidance
How do I improve my castle's appeal to new monsters?
To attract more monsters to your stronghold, you should install various pieces of devilish decor. Items like gargoyles and ritual altars are specifically designed to boost your castle's overall mystique, making it a more inviting place for potential minions.
What is the primary purpose of sending minions to explore?
Sending your monster minions to explore nearby towns and dungeons is a core mechanic for resource gathering. These expeditions allow your minions to return with valuable items, loot, and potentially even new allies to join your demonic forces.
How can I defend my castle against incoming adventurers?
You must utilize traps as essential equipment for your defense. By placing and combining different traps, such as sleep-inducing gas or heavy washbowls, you can thwart adventurers and work toward making your fortress of fiendishness virtually impregnable.
