Monster Eater

Rudd has been an E-rank labyrinth scavenger his entire adult life. His one inborn trait is total resistance to negative status effects, which sounds useful and pays nothing. After being left for dead by the party that hired him, abandoned without food at the bottom of a labyrinth, Rudd does the one thing his guild manual forbids: he eats the corpse of the monster that nearly killed him. The bite returns its abilities to him. The short-format series is Rudd climbing back up the labyrinth one mid-rank monster at a time, the new powers he absorbs along the way, and the people who decided he was disposable.
