Build? could you specify?If you mean useful skills, i prefer to prior, Strenght & DexterityI keep Stamina, all sword skills, Aard & Igni at high level and have intelligence at moderate. I don't tend to put talent points in Quen, Axii & YardenYou gain experience by killing monsters and doing quests, once you level find a fireplace or a person where you can meditate. Talking to proper npc will have a little symbol to the left. Fireplaces have to be burning ofcourse, you can fix that with flintstones. once you have started meditate you can create potions or spend your talent points. (check your right screen for the small symbols once you have started to meditate to go to your hero meny to spend talentpoints, or your alchemy meny to do alchemy, check quests etc.)You gain Bronze talents from level 1 and so on, Silver talents from level 15 and so on and Gold talents from level 30 and so on.Combat system works that you klick your enemy, then geralt do a short serie, once you see your mouse cursor turning into a flaming sword, klick again and let Geralt do the entire combo, once he is done klick again as soon as you see the flaming cursor again.Tactis depends on your enemy, Group style for several enemies, Strong style for some and fast for some other singular enemies. I suggest you start with Strong style when facing one opponent, if you see the enemy is dodging alot switch to fast since then he is probably a enemy you shall use fast steel/silver to kill.I suggest playing at Normal difficult and spend some time making pots aswell. Mainly Swallow. You need to know about the monsters in your beastiary if you have a quest regarding them. alot can be learned by books and recipies.
