How Jump works

Long Jump
You can jump a number of feet equal to your Strength score with 10 feet of movement before jump, otherwise only half that distance.
Either way, each foot you jump equals one foot of movement.

High Jump
You can jump the number of feet equal to 3 plus your Strength modifier (minimum of 0 feet) with 10 feet before the jump.
Otherwise only half that distance.
