The Whapper Sword is a melee-type weapon that can be obtained in the Frontier. This weapon can be obtained by defeating the Whapper at Blackrock Mountain or by purchasing it from Reus the Smith in Topple Town. This weapon is considered to be a rare drop from the Whapper, making it a difficult item to get for those who claim they are unlucky.
The player can use its special attack, known as Magic Smash. It is also known that this is the main weapon that Whappers uses to attack the players.
In appearance, it's a peculiar greatsword that came from the dimensions afar, as implied by its description. Its tip could be found on the Otherworldly Weaponsmith. It has a navy blue blade, as well as a brown, leather-like handle.
