Necromancer

Necromancers wield the forbidden magic of death and can corrupt their  enemies and the very land they walk upon. They can raise the dead to  serve them as their mindless undead servants and cast plagues to slowly  kill the enemy.

Necromancers are spellcasters who wield very light armor and are armed with scythes, tomes and daggers.

Necromancer specializations are Reaper, Unholy and Siphoner.

Reaper focuses on corruption and weakening of the enemy with different diseases, plagues and curses. 

Unholy is the master of the dead and can improve the Necromancer's  undead servants to be more powerful. They can also summon much more  deadly abominations to their aid.

Siphoner drains the very life and soul out of the enemy to improve and heal the Necromancer in combat.
