Command card: Son of Skywalker, is priority 1. It only commands Luke and gives him a free attack after his first attack.
Luke also has charge, which nets him a free attack after using a move action.
With jump he can also clear terrain at height 1 during his move. Thus Luke can, in one turn, leap a building and do 18 black dice worth of damage to let’s say, Darth Vader. For an average of 6-7 hits (taking into account Vader’s great defense). So, approximately half the time, Luke can drop Vader in one round.
