Agility

A ship's agility is the green number on its Ship card. It indicates the number of defense dice the ship rolls when defending.
 * A ship with an agility value of "0" can still roll additional defense dice granted by range combat bonuses, obstructed attacks, card abilities, etc.
 * All modifiers to agility are cumulative. After all modifiers have been applied, if a ship's agility, value is less than "0", it is treated as "0".
