Rednusadner is a weapon in Dragon Quest Swords. It is first given to the hero after defeating Draug in the Mirror World. This sword also teaches the hero the Figure of Fate Master Stroke which is used in the story of the game to open the Red Sea. It can be tempered into a Aurora Blade using 3 Lava Lump, 3 Ice Crystal, 3 Thunderball, and 1 Gold Bar. Additional copies of the sword can be received from Draug after tempering the first one. Rednusadner backwards is "rend asunder".
- The name Rednusadner is derived from the phrase "rend asunder", fittingly reversed for a weapon made in the Mirror World.
