Rulings

 * If a monster with Soulguard discards its soul to avoid its destruction, Penetrate damage still occurs.
 * This ability is also possible with a Link Attack. Should the monster in opponent's center area be destroyed by a link attack, damage will be given to the opponent fighter from the card with 'Penetrate' ability only. If 2 or more monsters in the Link Attack have penetrate, the combined critical from all the monsters with penetrate will be dealt as damage.
 * If the attack target of a monster with Penetrate leaves the field, Penetrate damage is not dealt.
