Dwarf versus Necromancer.

Actually, it's quite difficult for a Necromancer to defeat a well-played Dwarf. Choose Inga or Ingvar. On the very first day, immediately build a market and a warehouse. During the first week, upgrade your warriors, build a guild, and capture a mine and a lumber mill. Then, build bears and grab the gems. Don't hesitate to train a second hero who will roam the map and collect everything that's lying around. You need to focus on developing light, defense, and attack skills. First, prioritize upgrading the guild to at least level 3 and fully developing the rune school. Most Necromancers at the start use Kaspar with a ballista, ranged units, and summons. So, if you intercept him somewhere on the map, Kaspar will definitely lose. It will be easier after that, but don't drag it out too long, no later than the fifth month.
