The desert sand shifts intensely!

The Great Sand Shark is a Hardmode mini boss that spawns during a Sandstorm after killing 10 Sand Sharks once Plantera has been defeated. Alternatively, it can be summoned manually by using a Sandstorm's Core in a Desert at any time. While it swims through sand like the more common Sand Shark, it has a much greater variety of attacks on top of its increased size, speed, health and damage, making it a dangerous foe. It always drops a Grand Scale when defeated, which can be used to upgrade various weapons into more powerful versions of themselves.

It typically performs horizontal leaps towards the player's direction, but it may also perform a vertical leap aiming straight for the player. When it leaps out of the sand, it may also cause an eruption of Sand BlastSand Blasts. It is also capable of redirecting itself while in a leap and executing a charge in midair. If the player strays too far away from it, it will perform a series of very long charges until it returns to their vicinity.

After dropping below 50% / 75% Expert Mode health, it will begin to periodically summon Sand Sharks.

  • All Sand Shark alternate variants will also count towards spawning the Great Sand Shark, including Fusion Feeders.
    • Even Sand Sharks that are summoned by the Great Sand Shark itself will count towards spawning one in, so if the player wanted to fight another one, they can let the Great Sand Shark live for a while and kill some of the Sand Sharks it spawns.
  • Despite being intended to be fought after Plantera, the Great Sand Shark can be fought earlier if the player also defeats the Ravager earlier than intended.


  • The BestiaryBestiary entry for the Great Sand Shark: "These intelligent predators once swam the shores of the upper Ilmeran Sea, with many being trained to hold back Yharim’s forces. Yet when the day came, the sand sharks were barely even a distraction for the Supreme Witch, with this particular specimen surviving only by making a hasty retreat."
  • The Great Sand Shark and its associated items (with the exceptions of the Sandslasher and Sand Shark Tooth Necklace), were implemented based on a community suggestion made by ijones72 and ThatGuy on the mod's Discord server.
  • If the Boss Checklist Mod is installed, its unique despawn message will be "The apex predator of the sands disappears between the dunes..."
