The Sandduster is a chocolate brown sword, containing a yellow-golden outline and a slim diamond mark right above the hilt, the hilt mimicking the colors of the blade. It is only obtainable by defeating the mini boss on Floor 5, known as the Fire Scorpion.
The Sandduster is known for its rarity and high value as it is very rarely dropped by the Fire Scorpion.
The price of this sword has not skyrocketed to 50 million, even if the demand is fairly high. Like frostbite, this sword has dropped from a former price due to duping. A standard acceptable price of 30 million as min AUSP is the recommended.
