Improved BoS is a mod that changes how the game works for certain NPCs. It will improve your experience for a variety of different reasons. First and most importantly, it will make the game more fun for you. This is because it is more enjoyable to play with a greater number of NPC spawns. It will also increase the amount of time you can spend in-game.

It works by improving the spawn rate of certain NPCs. The new NPC has a higher spawn rate than the old one and is therefore more likely to appear in-game.
