Dragon Slayer IV: Drasle Family (ドラゴンスレイヤーIV ドラスレファミリー?), released as Legacy of the Wizard in the United States, is a fantasy-themed action role-playing platform game released for the MSX and Famicom in Japan and for the Nintendo Entertainment System in the United States. Dragon Slayer IV is an installment in Falcom's Dragon Slayer series, and one of only three Dragon Slayer games to make it to the United States. The game was an early example of an open-world, non-linear action RPG, combining action-RPG gameplay with "Metroidvania" style action-adventure elements.
