If the toughness of a character is decreased to a value of zero or less, that character is discarded.
Still a little confused on this game action. So if a character toughness is reduced to zero by a special ability in battle, is the card immediately discarded or does the player get special initiative? Since the entry doesn't state immediately even though I've heard otherwise I'm assuming they do get SI because they are being removed from battle. Would somebody please clarify this for my own sanity.
