Very quick question (no math). In the skill benefits area of the class descriptions, some classes have a skill or two listed as "Trained" (wizard has two I think, but books are at home) and then a list of skills from which to choose additional skills (# dependent on class). The trained skills are also on this list. What's the deal here? Are the "trained" skills listed at the front in addition to the other ones? If they're additional, why are they also listed in the pool of skills to "choose" from? If not, what's the significance of that notation?
