Divine Oil of Darkness and Immortal Holy Spring

"Why does every undead ritual need the liver of a ghoul?

"Should I get a few ghouls to raise? This way, it'll be easier to obtain materials locally in the future."

Matthew cursed in his heart.

He remembered that the Night of the Undead ritual had also used the liver of a ghoul as a special material.

However, he was only thinking about it.

Ghouls were undead creatures that were difficult to control. Very few necromancers would raise them.

The reason was that the ghouls were born with the deadly " Hunger Troubles ".

They would uncontrollably eat everything they could come into contact with.

Even if they were not hungry at all.

This flaw was not unique to ghouls. In fact, middle-level undead creatures were publicly recognized as the hardest to raise.

Ghouls eat everything;

Vampires were bloodthirsty;

Banshees liked to tear things apart.
