Victor of Tucson
Plum Parrot
Victor, a Tucson wrestler hoping for a community-college scholarship, is summoned to a System-controlled world and sold into slavery as a pit fighter. With no levels, no Energy, and no class, he must survive the pits by fighting above his expected capabilities, earning Energy — the universal resource for levels, skills and magic — and unlocking a Berserk-class progression. After breaking from slavery, Victor delves dungeons, hunts spirits, inherits Titan Blood and later Magma Heart powers, and climbs through Earthshaker, Sojourner, Champion, Void-Forged and World-Walker stages. From the author of Falling with Folded Wings (MC Gallup writing as Plum Parrot), the 11-book series is noted for isekai, System apocalypse, and gritty pit-fighter to world-walker advancement.
Progression: Explicit System-centric LitRPG progression central to every volume. Core resource is 'Energy' — a grab-all that builds levels, powers magic and skills. Progression quantified via levels, Classes (notably Berserk / Pit Fighter lineage), Skills/Abilities earned on Energy gain, and hierarchical power tiers (Pit Fighter → Dungeon Delver → Spirit Hunter → Titan Blood → Battlemaster → Magma Heart → Earthshaker → Sojourner → Champion → Void Forged → World Walker). Reviews highlight hierarchical class/race/world system, dungeon progression, spirit cultivation elements, and Titan/Magma lineage power evolutions. Level gaps of 80+ are plot-relevant; bonuses trigger when underestimated Energy is finally earned. System messages are a prominent diegetic element.
