Movement

Jumping
There are no creatures that can change direction in mid air except a in Bird or bat. So you must land. Flips back is about the only once we except you are landing.If someone forgets to land after a jump, their next action will be voided.

For Example.
PA: "jumps quickly towards PB"
PA: "swings at his chest"
PA: "rips his chest open"
No hit do to not landing.

For example
PA: "Jumps into the air"
PA: "Throws a kick at jaw"
PA: "Hears the jaw break"
PA: "Lands beside him."
Is a hit because he landed after kick can be visualized.

Leaping
If leaping from a high spot, such as a tree, rafters, etc. It would be possible. With a fresh character to Make attacking motion and Make hit point if they landed afterwards.

For example
PA is in tree, PB is on ground.
PA:"Dives downwards towards PB"
PA:"Swings sword at Neck"
PA:"Slices deeply across throat"
PA:"Lands quickly on feet."

It is best at all times to make complete moves. Do not assume that the Keepers will know what you were thinking. They deal with the scroll before them, not the wishes of others.

Tackles
A tackle must consist of three moves, a dive at the person, a grab at a body part, and the tackle. It is usually wise to close distance before diving as well.

For example
PA:"Dives at PBs ankles"
PA:"Grabs Hold of ankles"
PA:"Tackles PB to the ground"
This is legal because there is three lines
