When using skills, be sure to state that you are using the skill, roll the Skill Success die, and you have the result.
In example, Asuna has a cooking skill of 40, she rolls a 20, her cooking was successful, however if she rolled a 50, then she had failed.
if the number you roll is higher than your skill level, than you automatically fail, if it is spot on or below, then you are successful. Skill levels 1 to 10 are only successful at 1.
