Functionally; Taguel Fang possesses three attributes. It is effective against Cavalry units, likely in reference to the Beastbane skill. It also provides the standard beast transformation effect of Attack +2 if she starts the turn adjacent to beast or dragon allies; or alone, with the cavalry effect of countering follow-up attacks and inflicting an in combat Attack & Defense debuff when she initiates. If Panne meets her transformation criteria when she enters combat, she gets +3 to all stats.
