The tension between workshop and battlefield is one of my favorite dynamics when done right. So many litRPGs dump the protagonist into a forge for a few chapters, give them a cool hammer, then forget about it once the real monster slaying begins. A crafter MC lives or dies by whether the crafting feels integral to their problem-solving, not just a side hustle. In 'The Wandering Inn', the innkeeper class is a form of crafting a safe space, and the conflict comes from defending that creation. That's the model I love: the crafting defines the stakes of the combat. The smith isn't just fighting to survive; they're fighting to protect the workshop that lets them be who they are.
The best balance I've seen avoids a 50/50 split. It's more like 80/20, with the 80% being preparation, resource gathering, and social bargaining for rare materials. The actual combat is the explosive, high-stakes test of that preparation. When the alchemist finally throws that custom potion to dissolve the dungeon wall, the combat is a direct result of their craft. It flips the script—instead of getting stronger to fight better, they fight to enable better crafting. That's a loop that keeps me hooked far more than another generic strength stat grind.
