Lord Partizans have good medium range attacks, but don't excel at "sweeping" attacks like Flick Reapers. Their defense and physical attack stats are very high, with magical attack being their only real weakness. They're also more monster-oriented, with a lot of good armor-piercing and anti-air weapons and skills. Their skill progression for low levels is also among the lowest. Overall, this class can cause the most immediate damage.
