Skills are non-magical abilities, ranging from mundane tasks to heroic feats. Using most skills requires endurance points (see: help using skills) although some are passive or automatic and exact no cost for being in effect.
Your training in your skills (see: show skills) varies depending on how many times you have trained (see: help training), what skill bonuses you have earned (from levels and other sources, such as equipment), environmental effects (being underwater gives most races a penalty), and armor bulk (see: help bulk).
To learn the description of any skill, use the help skill name command. For example, help skill fire building is a common skill, and help skill attack is a common auto skill.
