Welcome to the TRPG Another World

I was in the middle of heading to a friend's house to play TRPG (Tabletop Role-Playing Game) when I was suddenly transported to another world. When I came to, I had become the character I had created and found myself in an unfamiliar grassland. However, this character has a young rear-guard setting that cannot survive without protection from other players—a tumultuous life begins!? This is a story about a production-focused support character growing stronger. The rulebook used in this story was created by a friend, and the system allows players to build up jobs, skills, and abilities to become superhuman. Please note that it has a chuunibyou flavor to it. Also, since it's impossible to roll dice every time in the story, damage and other values are calculated using expected values. I had written that I would act only once the success rate reached 100%, but since that became difficult, I'm doing so as much as possible, and when the success rate is less than 100%, I obediently roll the dice.
