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.
Circumstance Modifiers
Environment and hastiness can effect the difficulty of an action. Add 2 to the difficulty modifiers for unfavorable circumstances. Add 4 to the difficulty modifiers for hostile conditions. Modifiers for unfavorable circumstances and hostile conditions are not added to other modifiers for unfavorable circumstances or hostile conditions. When more than one of these modifiers apply, use the modifier which increases the difficulty the most. If multiple unfavorable circumstances compound each other, treat the combination as hostile conditions by adding 4 to the difficulty instead of 2.
Add 2 to the success modifiers for favorable circumstances, or add 4 to the success modifiers for very favorable circumstances. Modifiers for favorable or very favorable circumstances are not added to other modifiers for favorable or very favorable circumstances. When more than one of these modifiers apply, use the best one. If a combination of favorable circumstances is much better than the individual circumstances, treat the combination as a single very favorable circumstance by adding 4 to the success modifiers instead of 2.
