Namasioth (オナマズン, Onamazun) is a Piscine Wyvern.


Namasioth is a large, flightless Piscine Wyvern that shares the same overall body structure with Cephadrome and Lavasioth. A jade green shell covers its body with a lighter color belly and jagged yellow lines running its length. Its head is large, round, and sports fang-like extensions of its shell and has three pairs of barbels on its face. Namasioth has a pair of medium-length pectoral fins with jagged edges. Its tail is long and laterally flattened with a fin running both above and below the tail.


Namasioth is able to produce an electric shock of up to 350,000 volts using an electric organ. It can fire a concentrated stream of electricity from its mouth, or launch more condensed projectiles. It has powerful jaws and strong fins used to crush prey in its mouth and burrow underground, respectively.


Namasioth is a voracious predator. It uses its electrical discharges to stun prey. It is an opportunistic feeder and will feed on any readily available prey in its habitat.


Namasioth can only be encountered within the Marshlands and Sunken Hollow.


  • Namasioth is based off an electric catfish.
  • Its name is derived from ナマズ namazu (catish).
  • Each forelimb and the back can be broken. The head can be broken twice.
  • When it is low on stamina, Namasioth cannot use its electric attacks.
