Nightwalker
A Nightwalker is an artificial Heartless.
They are ghostly Heartless and they hover in midair. They use ghost-fire for long-range attacks but also use their claws for close range attacks. They can be difficult to defeat if one is low leveled, due to their aerial attacks and sweeps. They have no Reaction Command to help you defeat them.
It is an Emblem Heartless, and it is located on top of its hat. This makes it difficult to determine whether its type, much like Bulky Vendors, Creeper Plants, and Rabid Dogs, all three have emblems that are either very small, or in places many don't look at.
Attacks
Claw: Nightwalkers swipe twice with their claws, so continue to defend even after the first claw swipe.
Tailspin Charge: Nightwalker spins in the air, so it's best to wait for the attack to end from a distance before running in to attack.
Spin Slash: The Nightwalker spins either on the ground or in midair but very close to it. A strategy similar to its Tailspin Charge is effective.
Appearance
Nightwalkers have an appearance similar to that of a Chinese demon. A small parchment covering their face implies they are in fact cursed beings.
They wear crimson Chinese robes, but with a deep violet intricate design. The same goes for the hats they wear, which are traditional Chinese top-wear.
