Kaius just wanted to unlock his class - instead, he restarted the apocalypse. After years of training, Kaius has barely acquired the first two of his family’s legacy skills. Powerful and vanishingly rare, the method of creating them is a secret people would kill for. Now they might be the only thing that keeps him alive. Narrowly surviving a bandit ambush, he gets trapped in the Great Depths- a world spanning dungeon. To escape, he will have to slay one of the Guardians that defend the exits; a feat no one without a class has survived. Ever. If that wasn’t bad enough, if he succeeds he will reignite a forgotten trial that nearly ended civilization. -Runic-Tattoo Wizard/Spellblade in a world of sorcerers -Exceptional MC, with some initial Slow Burn elements -Large scope, inspired by epics such as Azarinth Healer, BTDEM, PH, and more. -Third Person POV, with a 99% MC focus -Numbers go brrrr -Attack Badger (Friendly?) -Battle maniac MC who is not a murderhobo -No harem, romance, or VR
