Lineage II/Necromancer

The necromancer is very divserse class. Not only are they capable of high level sumon magic like their Warlock counterparts, but have the hardest hitting spell available for human caster classes. Many consider the class a middle ground between a Spellhowler and the previously stated Warlock for their use of dark magic and summon skills.

As well as the types of magic already included, the necro has access to more curses of any other class, including the ability to push hate between mobs, paralyzing enemy PC's and a variaty of DOTs (Damage over Time). Not a specialized class but rather one with options.
