"Into The Great Wilde Open"
Decide how far you want to jump, and that sets the Difficulty of your Might roll. For a standing jump, subtract 4 from the distance (in feet) to determine the Difficulty of the jump. For example, jumping 10 feet has a Difficulty of 6.
If you run an Immediate distance before jumping, it counts as an Asset, reducing the Difficulty of the jump by one step.
If you run a Short distance before jumping, divide the jump distance (in feet) by 2 and then subtract 4 to determine the Difficulty of the jump. Because you’re running an Immediate distance (and then some), you also count your running as an Asset. For example, jumping a distance of 20 feet with a Short running start has a difficulty of 5 (20 feet divided by 2 is 10, minus 4 is 6, minus 1 for running an Immediate distance).
Being Skilled in jumping reduces the Difficulty of this Task.
For a vertical jump, the distance you clear (in feet) is equal to the Difficulty of the jumping task. If you run an Immediate distance, it counts as an Asset, reducing the Difficulty of the jump by one step.
Alternatively, you can ignore the math and use the Jump Distance table on Page 103 of the Core Rulebook.
