Most people never reach their limit. Peter will break his a thousand times.
Summoned as a legendary outworlder, Peter selects the [Fast Learner] skill, but as soon as he reaches level 5, he hits a level cap?! Turns out the world's system hates him, and in a crazy and unfamiliar world where even the trees can eat you, being weaker than a child isn't exactly ideal.
After saving a strange and mysterious girl, Peter is offered a new way to gain power, but it comes with a cost. His new and rare class will kill him if he doesn't manage it properly, but at least he's got some cool magic to throw around now. Not like he doesn't need it, what with the local lord looking to murder him all of a sudden.
Survival's one thing, but being a hero is HARD when you suddenly acquire a taste for souls.
