Dragon Slayer Gaiden - Nemuri no Oukan — About this game
Choose one of four professions and explore a world threatened by dragons released from the Sleeping Crown. Knight, wizard, hunter and tanker approach real-time combat differently, making weapon choice and positioning part of the adventure. Town conversations and outdoor routes lead toward dungeons and stronger foes. Check equipment and supplies before leaving safety, and learn an attack’s reach against a nearby enemy before chasing it into a crowded room.
