Ple-Sen
Auto-translated
kill monsters; if you see a group of weaklings, wait until they multiply (unless they are guarding something important); if there are peasant huts and other free, numerous weaklings, you need to bring them to the city. Otherwise, just fight. This is a well-known truth, and I agree with Andrei that the question is rather silly, especially since he could have asked his Necromancer friend how to act; I think he would explain.
