The Gnasher is a Pre-Hardmode enemy that spawns in the Sulphurous Sea. It walks towards the player in an attempt to deal contact damage and inflict them with the Irradiated debuff.


  • The BestiaryBestiary entry for the Gnasher: "Though gnashers are relatively slow, these mutated snapping turtles boast an unnaturally strong shell. Attempting to kill and eat one would injure most creatures greatly due to its terrifying biting power and spiked shell easily capable of impaling flesh."
  • The Gnasher is likely based off of a snapping turtle, which both live in murky waters. Though real life snapping turtles aren't known for killing humans, they are capable of causing grievous injury with their powerful bites.
