Assassin/Ninja Best Assassin Build?

I just started a a new character as an assassin and want like to know a good build. I haven't played in a few years so I don't know many things about builds.

 

At your level currently you don't need to worry much about a build, especially for your first play through. Mainly you should just try to pick up items with the following ids
Mana regen
Hp
xp bonus

On top of this stay away from items with the following ids
-hp regen
-hp regen %
-mana regen
-mana steal
-xp bonus

Other than this really until near endgame (upper level 80s) you don't really need to start investing in a build. After your first playthrough when you feel comfortable playing and want to solo alone and you have money you can invest in earlier game builds.

 

Doesn't really matter unless you already have minus raw hpr.
