Skills
Skills are the things your character can do. They're the basic means by which a character interacts with the world. Skills are heavily influenced by Class. Some skills are there for everyone, some are shared across similar classes, some are completely proprietary to the one class that practices them. Most Races have Skills resulting from their ancestry or native environment. Skills are purchased with Skill Points and every Skill has a description of what it does, what (if anything) it costs to employ, how often it can be used, and what underlying skills are required for it.
