[Quasi-Eldritch Essence is used to describe what keeps lifeless Eldritch constructs active. Every being whether possessing a Soul or not has some sort of unit of 'life' that keeps them active.
These Beasts lack individuality, they lack a life of their own, and they are created soulless with a single purpose- To destroy. As such, although they possess Eldritch Essence, it is merely a sub-unit of their creator, hence why it is a Quasi-Eldritch Essence rather than a true one.]
"Huh," Evian let out but his Assistant was not yet done.
[True Eldritch Essence is usually equal to a Soul Essence... I.e One unit of Eldritch Essence equals one Soul Point.
However, as a sub Essence that is merely a unit granted by the creator to keep them active, the Quasi-Essence you retrieve here is in no way equal to a Soul Point.
If you wish to make the Exchange, it will go by Fifty Quasi-Essence for a single Soul Point.]
