I don't like bumping old threads but this may be helpful to newer players who haven't read tips elsewhere. It is crucial to select skills that are defensive which will protect your toon when it is being attacked, especially by boss monsters, demon mages, and the like. I prefer to focus on one skill set per character, and master the magic and focus and the main defensive skills as soon as possible. For new builds with no others to pass on special items and weapons in the shared chest, bargaining is helpful (poor Shadow Warrior doesn't have this skill) to buy rings and amulets to forge protection and additional damage, skills, etc. It's advisable to use items that have many sockets for forging amulets (best) rings (good) and runes (helps ones buffs). Remember that when you choose a skill you can't change it, so be purposeful and know why you are selecting it.
