Honestly, I always found the training regimen at Gehenna to be a bit inconsistent, which kind of fits the chaotic vibe of the place. The core seems to be a brutal, sink-or-swim philosophy where theoretical lessons are minimal—they just throw you into practical scenarios. Like, in the hellhound summoning elective, your first class might literally be in a warded pit with a juvenile hellhound you're supposed to bind before it bites your arm off. No safety demos. It's less about structured progression and more about forcing power to manifest under life-or-death pressure, which I guess weeds out the weak.
There's also a heavy emphasis on peer-to-peer combat and power negotiation. Dueling clubs aren't extracurricular; they're mandatory survival practice. You learn by fighting classmates who might have completely incompatible abilities, forcing you to adapt on the fly. The faculty intervenes only if someone's about to die permanently, which creates this constant, low-grade terror that supposedly sharpens your instincts. It's not a system I'd recommend for everyone, but it definitely produces mages who can think fast in a crisis.
The library archives are another weird training tool—they're sentient and hostile. Trying to research a spell means outwitting predatory bookshelves and negotiating with cursed tomes, so even book learning is a physical and magical trial. You don't just memorize incantations; you steal knowledge from entities that don't want to give it up.
