Reading through the entire guide start to finish will take some time, so it may make more sense to focus your reading on sections that interest you.
If you are looking for a very quick pass on the perks then I suggest just checking out the summary section of each perk and then skimming through any sections of interest. This guide will of course be subjected to my own biases, but I will still point out good ways to use perks that I don’t personally like. I have cleared crises in a no-perks challenge and I’ve heard rumors of people beating the Black Monolith without perks, so you do not need to stress so much about min-maxing or creating perfect builds.
You can be successful in Battle Brothers (BB) using many different strategies so bear in mind that even if I do not value a perk highly it doesn’t mean you can’t make it work. I wrote this guide so that people would get all the necessary information to make educated decisions when selecting perks. I want to put out a guide that is current to the existing DLC, that goes into a high level of detail and nuance for each perk and their general usefulness, while also providing use cases on when you might want to choose a specific perk. With the Blazing Deserts (BD) DLC and the Switch release on the horizon, we will likely see an influx of new players that will be seeking assistance.
