Bone Necromancer
The Bone Necromancer tackles a large variety of monsters by mixing the Magic damage of Bone Spear and the Fire and Physical Damage of Corpse Explosion. Additionally, with his Bone Armor for Damage Absorb and Bone Prison for crowd control, he is extremely safe and great for a beginner. His biggest downside is a slight lack of damage early on during leveling until he gets more Skills or Levels.

Video Build Guide
If you are looking for a decent Damage Per Second build that can become very strong in late game, this is a fantastic build for you.
One of the big keys for the Necromancer overall is Corpse Explosion as it brings in Fire and Physical Damage types to your arsenal as well as has a massive Area of Effect.
