There is a specific pamphlet about each of the nine classes, but not one for him.
There is a more general pamphlet about common skills and what stats they require to purchase. Requirements for unlocking a skill and requirements for purchasing a skill do not seem to overlap. Most skills require one of your stats to be above a certain number before you can purchase the skill. Apparently, you can also purchase the same skill multiple times to make it more powerful, but this is usually considered an inefficient use of skill points.
There is an explanation of elemental affinities, which boils down to spells of that element making you less tired by the percentage of your affinity. Perfect affinities are extremely rare, so Coventina's 100% Water affinity is probably because she's a goddess. 100% Affinity allows one to cast spells of that element for free.
There is also a pamphlet on basic wilderness survival, and one which seems to be full of advertisements for blacksmiths and leatherworkers and alchemists.
Laurent has time to read them all. Coventina does not reappear promptly.
