Vampire wraiths (enemies)

Vampire Wraiths are the souls of vampires whose bodies have been put into a death state (vampires can't be completely killed until their souls are devoured then as proof of their complete death their bodies turn to ash &/or completely disappear) & while in their death state their souls wander the spectral realm until their vampiric natures adapt to that plane(from drinking blood to using the soul suck ability). As proof they go from being orbs or figures of light to having an actual spectral solid form that doesn't glow, this means they have officially become creatures of the spectral plane but, like the sluagh when completely weakened their solid form will become transparent, & when that happens any soul-devouring creature like e.g. the Archon can devour them because their solid form is no longer solid but in-between their glowing spirit-form & their solid spirit-form, regardless to a soul-devourer as long as the soul isn't completely solid they can "eat them whole" otherwise when they are solid the Archons will have to use the "soul suck" ability.
