To be safe and informed I will give you a survival difficulty chart for archetypes that will be listed in some chapters:
★☆☆☆☆ - Easy (1/5)
Harmless, but mildly annoying. You will live.
★★☆☆☆ - Manageable (2/5)
More annoying, but you still live with a basic level of awareness.
★★★☆☆ - Risky (3/5)
Potentially dangerous, just be alert.
★★★★☆ - Hazardous (4/5)
High chance of injury/chaos/emotional damage, be MORE ALERT.
★★★★★ - Extreme (5/5)
Only brave students will survive. Bear with caution.
★★★★★★ - Mathematically Impossible (6/5)
Breaks mathematical laws, physics, and safety. Even my favorite math teacher can't solve this rating. Just pray if you see this rating, PLEASE.
