Your LitRPG stat system is airtight. Your story has no pulse.

The most durable progression systems in LitRPG are built around one central constraint, a single rule the protagonist cannot break without consequence. Everything else, the skill trees, the stat thresholds, the level-up caps, should serve that constraint rather than expand endlessly around it. Power scaling breaks down when writers add mechanics to solve narrative problems instead of letting the story's emotional stakes do that work.

Non-gamer readers don't disengage because they don't understand status windows, they disengage because they stop caring about the character inside the stat sheet. Ground every level-up and skill acquisition in emotional consequence: what does gaining this ability cost the protagonist, and what does it make them afraid they're becoming. The dungeon diving and tower climbing are the setting; the character's interior is the story.

An OP protagonist loses tension not from raw power but from the absence of meaningful stakes. The fix isn't to introduce an even stronger boss fight, it's to make the protagonist's internal world as complex as their external power. What they cannot level-up out of: grief, identity, the cost of the grind itself. Readers will follow an overpowered protagonist anywhere if they believe the character still has something left to lose.

The grind bores readers when XP accumulation is the only thing changing. In every dungeon run, cultivation session, or tower climb, something in the protagonist's understanding of themselves should shift, even slightly. Vary the emotional register of each grinding sequence: let some feel triumphant, some hollow, some quietly terrifying. The mechanics are the container; the meaning is what fills it. Will Wight's Cradle series is a useful model here: Lindon's advancement almost never costs him nothing.
