Long Jump

When you make a Long Jump, you leap horizontally a number of feet up to your Strength score if you move at least 10 feet immediately before the jump. When you make a standing Long Jump, you can leap only half that distance. Either way, each foot you jump costs a foot of movement.

If you land in Difficult Terrain, you must succeed on a DC 10 Dexterity (Acrobatics) check or fall Prone condition.

This Long Jump rule assumes that the height of the jump doesn’t matter, such as a jump across a stream or chasm.
