Open Dark Arts and read the two areas
Open the Dark Arts screen and separate the rites and crafts area from the spell schools. The developer’s Dark Arts overview in the Malignus press kit places rites and crafts above the schools. If you came to look for spells, focus on the lower area.
Find the four spell schools
The four documented schools are Pyromancy, Electromancy, Necromancy, and Shadowmancy. Pick the school you want to explore and read the details of the selected entry. The school name gets you to the right branch, while the individual entry tells you what you are looking at.
Use Pyromancy III as a menu example
Mossbomb’s screenshot caption identifies Pyromancy III as the entry selected in the Dark Arts screen. That gives you a concrete example of how a school’s details appear. Check the entries in your own build before planning around a particular unlock. Go back to rites and crafts when your goal is a ritual instead of a spell-school entry.
