Twin Star, Jack & Fang/Tips


 * Penetrate counts as effect damage, so any Dragonarms that give it to a Neodragon (such as Dragonarms, Cavalier) would trigger this when it activates.
 * If the opponent is trying to wall you with a center monster with Soulguard and lots of soul, you can have a field day getting in multiple burns with this (as this is not once per turn) by getting in multiple attacks with penetrate. This can be done with Dragonarms, Radiant Alma and/or calling an Impact Monster (especially Jackknife "Full Liberate Cannon!", as then you can get even more burn damage in).
