Rolemaster characters have ten attributes, called "stats", which represent their natural abilities in such areas as physical strength, memory, self-discipline, agility. Both random and points-based methods for determining stat totals exist, but the final result will be a number on a percentile scale (1-100), which is then used to determine the character's skill bonus at actions which employ that stat. A self-governing system is in place also such that each skill closer to 100 is more costly than the last. Moving a skill from 50 to 51 is almost trivial; from 98 to 99 nigh impossible.
