In order to go up ranks, you must spar with either a classmate or a training dummy, and occasionally a Moglin known as Master Twang. If victorious, you must then succeed a Blade Skill check. In order to do that, you are given a randomly generated number between 1 and 100. If you are wearing the uniform, you are granted a +4 bonus to the roll. In order to gain a rank, the resultant number must be greater than or equal to the number that the game gives you. This number goes up as you advance through the ranks.
