|Task Difficulty||Base Chance||Per Skill Level|
The chance of success is the Base + Level * Per Level. If the situation has some special characteristic, the GM can add or subtract levels from the character's skill level.
For instance, a character with the Outdoors category is attempting to track a large cow walking down a muddy path. Tracking a cow is considered trivial, the mud is a bonus that the GM treats as a 1 level modifier; the character's chance is 20 Base, + 40 for the bonus level due to the mud, for a total of 60%.
A character with the Outdoors category is trying to track a large cow walking down a dry path. Total chance is 20% + 0; 20%.
A character with the Outdoors category is trying to track a wolf who is walking around the same path later walked by a large herd of cows. This is considered a hard task – base chance is -10%, +0 for level 0 in tracking; -10% total.
A character with the Outdoors category and 5 levels of tracking is trying to track a wolf who is walking around the same path later walked by a large herd of cows. This is considered a hard task – base chance is -10%, + (10 * 5) for level 5 in tracking; 40% total.
If more than one character is attempting a task, one is chosen to make the attempt, the others are assistants. The primary character's chance is adjusted by one-half the chance of each of the assistants to suceed. The total modifier for assistance cannot go higher than the primary character's unmodified chance.See the skills page for more detailed information about both non-weapon and weapon skills.
