Like all the other classes, the Necromancer will also get three different skill-trees with different themes. The Reaper will focus on dealing damage, so most of your damage output will come from this skill-tree. The Bone Tyrant will be interesting for the tanks, as most defensive abilities will be found in that skill-tree. The Living Death will focus on reanimating dead bodies and some sort of healing.
