Difficulty values are often determined by adding 10 to a modifier such as a character's ability level. This can be used to resolve contests between character's using different abilities or the same ability against each other. For example, suppose two characters are having a contest, and both have the same ability level. Adding that level to a die roll for one character and adding that level to a difficulty of 10 for the other character gives both characters a 50% chance of winning the contest.

If a contest can be tied, do two success rolls with each character taking turns adding their modifier to the roll or a difficulty of 10. One character can succeed while the other fails or the result can be tied two ways: both characters can succeed or both characters can fail. If it is not possible for both to succeed, then both characters fail when either type of tie occurs. If it is not possible for both to fail, then both character's succeed when either type of tie occurs.
