there a newbie build for the games?
The series clicked with me from the get go, so I can't really offer newbie advice as such, but for builds (and you're making it harder here as you're missing the two games that have super solid early game builds lmao):
For Dark Souls:
People will tell you to grab a Drake Sword. Under no circumstances should you do this. It is good early on, but it's outclassed by so many other things practically instantly. I'd pick up a shield, although I prefer to not use them- just means you should focus on increasing your stamina more. Stats wise, and this sort of applies to all 3, I'd focus on increasing health, stamina, and the main stat of your weapon (which could be 2 stats depending on what you're using). I'd avoid the 2 magic stats, but increase attunement to equip a few different pyromancies. Starting class doesn't matter at all, and take any gift other than the key.
Weapons and equipment wise, I'd try to keep your weight down so you could fast roll, and stick with a weapon that scales primarily with one stat. Most weapons are viable, so just find a moveset you like.
In terms of combat, make sure you manage your stamina, to allow evading if necessary, and try to kite enemies. I don't want to sound condescending, but you want to watch enemies attacks, and attack when they leave themselves open, and for bosses, being under them, if they're big, is usually the best cause of action. Other than that, try to stay behind them, and roll through their attacks.
