Overview
The Eurypterid is a small aquatic herbivore capable of breeding and damaging structures. It thrives in dark underwater zones and caves, making it a useful early-game option for underwater base construction or sabotage. The Eurypterid can be airlifted by Quetzal or Karkinos for fast deployment.
It is primarily used to harvest underwater resources and assist in underwater structural damage, especially in hard-to-reach areas.
