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.

Last Life

Alexey Osadchuk

Jack was gifted in his former life until a fatal confrontation sends his consciousness into Max Renard, illegitimate son of an executed traitor in a magical multiverse. On the frontier of Vestonia, he must master the Shadow of Strix — a cultivation-based magic where mages harness Shadow Power through training, mana-infused materials, and frontier trials — to rise from disgraced bastard to Margrave de Valier. Alexey Osadchuk's Last Life is a 12-book progression fantasy (explicitly marketed 'A Progression Fantasy Series' from book 11) blending reincarnation, ЛитRPG-style quantified advancement, and cultivation mechanics centered on Shadow cultivation, elite gifted talent, and political/military rank progression through frontier, court, and continental war arcs.
