Conditional dmg x Power and Precision
There aren’t really any good hybrid specs anymore, it is mostly either full power builds or full condition builds. Power builds are better in pretty much every way, but some people enjoy playing the condition builds. If you just want raw power get a mainhand dagger and use power/precision/ferocity gear. That will give you the best damage a necro can do. There are plenty of builds floating around this forum, so i’m sure you can find one to your liking as you level up.
Also none of your story choices have any effect on anything other than the story, and even then it is only a very limited effect, so choose whatever you want!
