What is a Night Walker in the game of Maple Story?

A Night Walker is the knight of darkness. They utilize stars as their weapons much like that of an assasin. They seem to be darkness based, however, they are actually poison based.

Ability Points
I suggest that you just follow the auto's way of doing things, unless you are out to make a Pure Luck Night Walker.However, things like equips mess with auto, so each time you level, take everything off and click it! XD
1st Job Adv.: The Knight in Training
Once your account is level 10, head over to the Night Walker Job instructer, Icarut (the guy sitting on the tree), to advance and become a Night Walker. Upon advancement, you will receive a medal, some training subis and a training claw, equip them.
