|Drops||Colorless Demon's Soul|
These corpulent, maggot-like demons will appear throughout the Archstones, generally in hard to reach or heavily guarded areas, at Pure Black World Tendency. They are near defenseless, although they can hurt the player with their mandibles should one get to close to their mouth. Primeval demons are immobile, and quite easy to defeat. Upon being vanquished, a Primeval Demon have a high chance to yield a Colorless Demon's Soul, which is used to upgrade unique weapons.
Without duping, up to five of these demons can spawn (one for each world) per playthrough, and consequently five Colorless Demon's Souls.
