It does scale, but within any time frame before scaling (not sure exactly how it scales or at what intervals) there is variability as to the difficulty of various groups. I avoided all camps when I first started back playing, as a result, until I had a better handle on the game. Now when I do camps and it doesn’t have scout information, I still go in, but if it is a guaranteed wipe, I quit out of the battel and load the autosave as it puts you back right before entering the camp.
I actually started a new run on the PC with the base game. Got a camp with a bunch of zombies and a necromancer, made it out with just one death and a legendary helmet. Seems like there were 12 or 15 of those weidergangers, but I got an achievement for killing over 24 enemies, so there were a buch of resurrections. It was actually right around day 25. I think I got lucky as the guy he possessed (that allows a zombie three attacks) missed just enough.
Skills are an ever changing thing for me. The base game requires focus on various builds and skills that then change with some of the expansion content so I am never sure what precisely to recommend and added to that I’m still stumbling around. But those changes to builds really only heavily come into play with certain enemies and during the high level end game fights. I usually retire after one or two of the "campaign objectives " (noble war, greenskin attack, whatever) are satisfied because I want to try something new.
Filthy Robot’s perk guides from 2017 are still pretty good for at least walking you through his interpretation of the value of various skills. Those ideas and recommendations have changed as he continued to play over the years and as DLC has been released, but I found that when starting out with the base game as I did on the Switch in March, these guides were still helpful. He has a separate video for each row of skills.
Here’s his build spreadsheet from the over a dozen seasons he’s streamed over the years with different builds he monkeyed with in each season.
I only continue to recommend him because I was lost when I played initially, was determined to learn the game at the time of the Switch release and found many of his early game guides and build videos very helpful in at least understanding the mechanics better and what the skills actually do. He even does a “very early” game guide for new players.
Filthy does a lot of analytics (A LOT) and in a later video he came to the conclusion that Fast adaptation doesn’t work quite like the description says and may not be as helpful, but I haven’t really tested it out and he still recommends it, but not for every brother.
I usually get colossus with guys that start with lower HP. I believe big hits that cause greater damage result in more frequent wounds as whether they get a wound is based on the percentage of total health a hit causes. Because you need to ramp up those stats, I start with Student (for levelling faster) often and follow up with gifted. For archers it may vary a bit. I like quick hands and rotate on most of my frontline guys. Quick hands allows you to switch to a dagger in your bag for free to kill guys with good gear without damaging it. Rotate allows you to get a frontline guy out that you want to save. But, honestly, I still don’t really follow to the letter his guides. I’m still fiddling around with things and for better or worse fall into the same patterns.
All of this is based on a significant amount of play, but also know I could have some details wrong because I have attempted to digest a ton of information in a short time. :) Others who played in the many years since its release earlier in the thread probably know better. They can certainly quote numbers and calculation far better than I can. I like to dig just deep enough into the mechanics to play, but not exhaustive examination by using build calculators and such to make sure I am min/maxing properly.
