Realm of Heroes

英雄の領域 · Magic & Power Systems · Levels & Classes

The New World's term for those who have broken through human limits; those who cross this line are called "heroes."

Locals have no concept of levels, yet they call those who surpass the human wall heroes, saying they have "stepped into the Realm of Heroes," so there seems to be some standard
The Web novel setting takes the ability to use 5th-tier magic as the standard for a hero; readers estimate about level 29 or higher (based on the seven-levels-per-tier theory)
Known hero-class figures include Lakyus, Clementine, Kelart, Remedios, Go Gin and members of the Black Scripture
Gazef originally only stepped into the Realm of Heroes temporarily with the help of a dragon-treasure ring; by Vol. 14 Brain had properly entered it and surpassed Gazef
Glossary in Japanese sources: Gazef, the strongest warrior of the neighboring nations, has not yet reached the Realm of Heroes himself; only a handful of adamantite-rank adventurers have; all members of the Black Scripture are hero-class or above
Readers' estimates rely on the "seven levels per tier" theory: 1st tier at levels 1–7, 5th tier at 29–35, 6th tier at 36–42, 10th tier from 64; the theory stems from the author confirming in an Arcadia reply to comments that the Web novel's level setting for Narberal was a mistake

Notes

The Web novel says that above the Realm of Heroes lies the realm of "gods."
