Sacred Haven of Debauchery

Yes, there are several types of NPCs. Some constantly complain about something, from "we're all going to die" to "look at us, buddy." There's an annoying NPC that you often want to kill, but as a rule, he's the strongest of all the NPCs, and at the same time, he has practically no loot. There's a friendly NPC who always responds with positive phrases and tries to help, but he's often killed because he has a lot of good loot. There are NPCs that cannot be killed because they are programmed with special code.
