As I mentioned OCC, I was going to list different types of Wraiths other than the Generals and up. They'll be in names and descriptions:
Ravers = Flying Wraiths, commonly resembling cloaked vultures with 2 pairs of eyes. Cannot use weapons.
Sentries = Army units, commonly autonomous suits of armor with nothing inside.
Dark Ryders = Skeletal Wraiths capable of riding Wraith-version animals or ground vehicles. Both vehicle and Ryder are destroyed if either is destroyed.
Nightmares = Wraith versions of horses. Used by Ryders and/or Generals.
Dread Drakes = Wraith versions of dragons of any type. Used by Ryders and/or Generals.
Creepers = Thief Wraiths. Able to move like insects or spiders, sometime having such features on human-like bodies.
Shadows = Assassin Wraiths. Typically living black silhouettes. Can hide in any shadows and take shapes of potential victims' shadows.
Cloakers = Reaper-like swordsmen (like the Ring Wraiths of LOTR) that can glide like falling bed sheets. Often referred as the elite fighters of Wraiths. Any sword can be used.
Faceless = Wraiths with naturally white bodies, black tattered robes, and no face. They have the ability to implant the face of a victim on its own head, and then take on the voice, personality, features, and clothing of the victim.
Grapplers = Large hooded Wraiths with heavily muscled arms used for ripping victims apart.
Slashers = Same size and look as the Phantom Grapplers, but with large claw-like arms and elongated nails
Rakers = Slightly smaller version of the Slasher
This is what I've thought of so far. Anyone's free to input their ideas of new Wraiths. Just none that could Summon or use magic.
