====Character Advancement====
 
There are four methods a player may utilize for improving a character’s skills. 
;Chance:Simply using a skill still gives a person a chance to improve, as they may simply figure something out by chance. The formula for this improvement follows:  100   ( (Skill + Potential) * 2 ) = Target. Where Skill is the skill the player is attempting to raise, and Potential is the appropriate Potential Attribute (Physical Potential for physical skills, and Mental Potential for mental skills). Another way to describe this formula is this: Add the values of the Skill and associated Potential Attrib, multiply this value by 2, then subtract this value from 100, this is the Target. Roll under this Target to improve by 1 point. This gain is limited to skill per <time unit>, which is to say that only one skill can be raised in this fashion per <time unit>, so the player should choose wisely which skill they wish to have raised.
;Practice:Actively practicing with a skill will give someone a greater chance to improve that skill, as you are concentrating on what you are doing and trying to figure out how to do better. Use the same formula as for Chance Improvement. Successful practice allows you to improve one skill per <time unit> by 3 points.
;Training:Training under a higher skilled teacher allows one to improve skills considerably, but also requires a teacher and a longer period of time. Use the same formula as for Chance Improvement. Training can only be performed once per <time unit>, and raises one skill by 5 points.
;Teaching:Teaching a less skilled student sometimes allows the teacher to learn new things as well. Use the same formula as for Chance Improvement. Teaching can only be performed with up to two students/skills per <time unit> and gives a skill increase of 2 points per student/skill.
