Wyrmslayer

The Wyrmslayer is a sword weapon found in quite a few games; like its name suggests, the weapon is effective against dragons, being able to triple your might against them. There are a total of three Wyrmslayers that can be obtained throughout the story in Fūin no Tsurugi; in Rekka no Ken, it is obtained in a village in Chapter 20; you might have to try a couple of times to dig up the Wyrmslayer in Sacred Stones's Chapter 15; and in Radiant Dawn, there are several of them, all of which come from Aimee in different chapters. The Wyrmslayer is analogous to the Dragonspear and the Dragon Axe, although neither of those two are in as many games as the Wyrmslayer is.
