The Master Necromancer - Vol 1 - Chapter 68

Skraal started inspecting the knowledge he had acquired from the system.

Cursed Conjuring: This knowledge was given about ideas of cursing,

It came in the form of a one-leaf document, which means that Skraal could not learn about this knowledge by just buying it. He has to learn about the information and history so that he can use or have a basic knowledge of the things written in the document.

Skraal opened and started inspecting the document on one leaf.

"Cursed conjuring is another type of conjuring that involves cursing the creature before summoning it; most of the users are necromancers or other evil types of summoners who curse their familiars or creatures before summoning them from other planes so they will have more power in their bodies and be more dangerous to the enemy itself."
