“Beginner” level was called “Normal” until quite recently. I’m not sure whether the actual difficulty has been altered since then. Whatever the difficulty level, there can always be points in the earlier part of the game where you’re very short on crowns and tools and in danger of being swarmed by a variety of enemies within a short space of time. It’s just that, on Normal/Beginner difficulty, you’ll have probably spent/wasted crowns on more recruits and equipment, and your enemies will be not quite so numerous and (towards the start) not so well-armed/protected, so that you’ll be more likely to come through and eventually reach the point where potential “ambush” parties run away from you and you always have (or can quickly acquire) an excess of crowns to spend on almost any single item/recruit you desire. Depending on the luck of map generation, resources/opportunities close to starting location, suitable/awkward contracts/enemies spawned, the actual difficulty of individual campaigns on the same difficulty setting can vary quite a bit.
