Underdog
Alexey Osadchuk
In a world governed by the Great System, Eric Bergman is born nulled — level zero with no characteristics points, unable to use experience essences or tablets. After his parents' deaths force him into debt slavery in the Dungeons of the Crooked Mountains, he must exploit low-level artifacts, tame dungeon monsters, and master the Great System's level, life, energy and mana mechanics to survive. Each volume tracks his explicit LitRPG advancement from crippled level-zero outcast to mage, Monster Hunter Magister and renegade, verified via Goodreads series description and per-book synopses showing Great System notifications, mana/characteristics growth and rank progression.
Progression: Great System LitRPG — explicit quantified advancement central: levels (Eric begins level zero/nulled), characteristics points (life, energy, mana), experience essences and characteristics tablets, artifacts with no level restriction, Great System notifications (Place of Power, mana route calculation), magical supply activation, monster taming, Chaos Magic and Citadel of Chaos Unity test, ranks (Magister of the Order of Monster Hunters, stripped to apostate/renegade). Advancement is System-governed with visible stats and level/rank gates; every book shows measurable power increase and System rank change, verified via Goodreads book descriptions (level zero, characteristics, Great System, Magister, Renegade).
