Dungeon Fighter Online/Thief

The Thief is a new class that is only available in the South Korean version. They are agile, dagger-wielding dark elves that specialize in high-speed attacks and aerial combat. The class is currently under development.

Thieves are able to advance to one of four forms. Rogues specialize in close-range combat and are skilled at dodging. Necromancers make use of the dark powers inherited from their dark elven blood, and are able to do battle with the aid of an undead servant. Kunoichi move quickly and utilize long-range and wide-area magic spells. Shadow Dancers rely on stealth and assassination techniques.

Necromancer
She disturbs the peace among the dead to use them as powerful allies in battle. Giving orders to her trusty dependable ghost servant Sir Nikolas assisting her in battle, she fights evil with evil, using magical dark-based attacks that curses enemies with various effects. The majority of her spells is mid ranged and deals Area of Effect (AoE) damage. She also seems to favor spells that deals damage over time instead of packing a powerful punch, like using zombies or ghosts that clings on her enemies or spirits that floats wildly in an area to deal repetitive damage.

She is especially powerful in magic as she uses a skill called Dark Ritual, which sacrifices her HP and a high percentage of her strength to give her a high percentage of intelligence.

At later levels, she can be "possessed" by a powerful minion called Vallace the Slaughterer (another ghost she will rely on in battle), moving in unisson with every attack of the Necromancer, replacing her normal physical attacks with powerful melee magic attacks, also giving her the opportunity to cast even deadlier spells.

Her weapon of choice are wands and she wears light armor.

An excellent choice for PvE, but a rather poorer choice for PvP, especially compared to the Rogue subclass.

The Necromancer can be identified by the dark flames surrounding her.
