Lol Vostatek is great. If you can’t get Pepik back, try going at night and sneak in and kill the camp leader with a knife to the throat while he’s sleeping. If you’re lucky you can kill two or three before the others notice. Also at night they don’t wear armor or weapons except the guy on guard.
Alternatively you can just run in and grab Pepik and get back to Vostatek post haste. The mission is to get the horse, the guys are just extra loot.
KCD2 is a game which rewards you for thinking outside the box. Frontal assaults don’t work unless you’re a sword god and henry ain’t that in the early game.
One tip i would give you so you don’t get overly frustrated is if you see what appears to be a combat situation (anyone hanging out on the road or beside it at camps) save the game by exiting. This makes an exit save which will be overwritten by the next exit save but it doesn’t cost you a saviour schnapps to save. This way you aren’t drunk in combat nor are you limited to saving only via schnapps. If you do that right as you see a combat encounter you should be able to try it a few times and if you can’t win just run or sneak past them.
I would suggest to load up an earlier save. The beginning is the hardest part of the game (like brutally hard combat sometimes) and if you don’t train Henry up (either find Tomcat or Captain Gnarly, they are trainers) you’ll just die. Or you can do what i did and just brute force the fight with save scumming. The combat is not intuitive until you practice for a bit.
Have you tried Kingdom Come Deliverance 2? It’s really good and difficult. It’s a history simulator with a really kick ass story and the hero is just a guy. I really like it a lot.
I have over a thousand hours in BG3 and i still find new stuff sometimes. Far less often now but still. You’ll find plenty of new story in a second or N+1 run.
