I'm always stubbornly insisting that there are no "builds" in Drakensang. "Builds" are something I see in Action-RPGs, and only there.
To be frank and honest, I really don't like th concept of "builds", since I believe that "building" distracts from playing a game just for fun.
Others might disagree, but this is m opinion. I don't play games for power-gaming or for optimizing, I play games solely for fun. And that's why I don't like the idea of "character building".
Of course, a character should actually be able to do a lot of things and especially be able to beat th main foes - but merely concentrating on the aspect of powerfulness in a game distracts from the fun for me. To me, role-playing games re thre for playing a role, not for "power-building".
And, of course, everyone defines "playing a role" very differently.
This is my opinion. Therefore, I'm biased. So take everything I write here with a grain of salt.
Drakensang is rather "old school", and you can came through it with anything you like to. It is bit more friendly in this respect to the player than Drakensang 1.
However, I'm not 100 % sure I remember this correctly, but there was once a thred in the official forums opened up by someone who said that Drakensang 2 was far too easy and therefore no fun. I believe that he was playing it like an Acton-RPG, complete with "builds" and power-gaming, like he used to know it from … well, Action-RPGs. That's how I saw it.
So, if you want a challenge, then invest points into oher areas as well. Especially into social interaction, that pays really off (except for etiquette, which is seldom used within the game - I remember only 1 case outside of the last main location).
What you should put as many points as possible into, is the … I think it's "willpower" in English. It's a skill or talent which keeps you from getting wounds.
You'll need that for fighting against big crabs much later (against which fire helps, too).
Do a right-click on every item in the character screen you want to know about.
And don't forget to put a few points into the main stats as well !
