While Stardew Valley is often celebrated for its relaxing gameplay, it also offers an impressive array of combat tools designed for adventurous players. Among the most formidable weapons you can acquire is the Galaxy Sword, which stands out as one of the game’s most powerful assets. To obtain this coveted sword, players must decipher a Dwarvish riddle involving the elusive Prismatic Shard—an item renowned for its rarity and vibrant colors.
Unlike other weapons that can be easily purchased or looted, acquiring the Galaxy Sword requires exploration and puzzle-solving. If you’re determined to wield this powerful instrument of combat and are curious about the location of the riddle, you’ll find it in the graveyard within the game. Once you have the sword, you’ll be well-equipped to tackle even the most daunting challenges that Stardew Valley presents.
How to Find a Prismatic Shard

The journey to securing the Galaxy Sword begins with obtaining a Prismatic Shard, a much sought-after item in the game. Here are several methods to enhance your odds of finding this rare mineral:
- Mining Mystic Stones: Delve into the Mines (especially floors 100 and above), Skull Cavern, and the Quarry, where these stones have a 25% chance of producing a Prismatic Shard.
- Breaking Meteorites: If a meteorite appears on your farm, using a Gold or Iridium pickaxe grants you a 25% chance of finding a shard.
- Looting Treasure Rooms: In Skull Cavern, these rooms provide a 1 in 26 chance of containing a Prismatic Shard.
- Mining Iridium Nodes: These nodes, located in the Skull Cavern, Quarry, and Volcano Dungeon, carry a 3.5% drop rate for shards.
- Cracking Open Omni Geodes: Found primarily in the Mines and Skull Cavern, these geodes present a modest 0.4% chance of yielding a Prismatic Shard.
- Opening Mystery Boxes: Similar to geodes, these boxes have a 0.4% chance of containing a shard, making each opportunity potentially worthwhile.
To further improve your chances, consider utilizing luck-enhancing food items before venturing into the Mines.
Unlocking the Galaxy Sword

After successfully obtaining a Prismatic Shard, your next destination is Calico Desert. If the desert is not yet accessible, you will need to repair the Bus by completing the Vault Bundles at the Community Center or by purchasing repairs from JojaMart.
Once in the desert, locate three towering stone pillars. Stand on the central tile with your Prismatic Shard, and an animation will commence, transforming the shard into the Galaxy Sword. This remarkable weapon not only deals between 60 and 80 damage but also grants a speed boost of +4, ensuring you remain competitive in combat. An added benefit is that the sword will remain in your possession, even if you are knocked out in the Mines.
If you happen to lose or sell the Galaxy Sword, you can acquire another from Marlon at the Adventurer’s Guild for a price of 50, 000g, allowing you to regain your powerful weapon with relative ease.
