When a Jedi successfully activates this power, he creates a protective shield around his body. This shield is effective against both energy and physical attacks. The strength of the shield is equal the character’s alter roll divided by three, rounded down. For example, if the Jedi has 9D in alter, he may add 3D to his Strength roll to resist damage. If the Jedi exceeds the alter difficulty by +10, he may extend the greater force shield to another character if he has direct contact with that character.
