On the following pages are skills available in most Savage Settings. Normal use of a skill–guiding a boat in and out of a dock, repairing an engine with plenty of time and the proper tools, or riding a horse across a prairie–shouldn't require a skill roll. Only when a character is under pressure to perform a task quickly, or has a significant chance of failure and can't just keep trying until he's successful, should his player be asked to roll.
