Transferable Job Skills
A character with skills in one mundane job find that said knowledge or skills are useful to their new exotic job.
Joe-Shmoe mathematician unexpectedly gets whisked to a magical universe then suddenly given the task of Saving the World. Luckily, the magic there has to do with numbers and everything he already knew from his old mundane job is useful and relevant, to the point that he's practically an Instant Expert! How convenient! Basically this trope is when mundane skills are transferable to being proficient at something not so mundane. The skills don't necessarily have to do with the character's former job, and may actually be more like skills developed from hobbies or interests. And while the new 'job' is often magical, it doesn't necessarily have to be, just significantly different and exotic by comparison in-universe. This is often a way to explain why a particular Na´ve Newcomer to a world or job becomes so badass so quickly. Related to Genre Savvy, as characters with knowledge of media, when finding themselves in situations similar to the media they know, often are able to dodge many of the problems their less savvy counterparts get into, precisely because they have this knowledge. Compare Boxing Lessons for Superman, when an already badass, super-powered character with an exotic job description learns more mundane skills to be even better, and Wax On, Wax Off, when mundane activities or chores are used as a training means. Contrast Mundane Utility and Martial Arts and Crafts, when exotic job skills are used to do very mundane things.

- Huey in Bibliotheca Mystica de Dantalian used to be a military pilot. His battle skills have saved his life more than once since inheriting the key to the Mystic Archive.

- In Harry Potter and the Methods of Rationality, Harry Potter-Evans-Verres breaks into the Potterverse with the power of SCIENCE! And a deep knowledge of cognitive bias and human rationality. And of economics. He is using that knowledge to make the most out of his limited magic powers (he's still eleven) and has undertaken the following programme: To understand everything important there is to know about the universe, apply that knowledge to become omnipotent, and use that power to rewrite reality because I have some objections to the way it works now.

- In The Librarian, the main character uses all the knowledge he's gained from being a full-time student-for-life and obtaining basically every degree known to man to aid him in finding dangerous treasure and locking it in The Library. In fact his ridiculous knowledge pool is why he's recruited in the first place.
