Somnacanth
Type	Large monster Leviathan		Threat lv	5 / 10
Element	—		Status	Stun Sleep Blast
Weak	Fire Thunder		Resist	Water Ice Dragon

Introduction

Description: A formidable aquatic serpent that crests on moonlit nights—likely why it has often been mistaken for a mermaid. It expels an intoxicating sleep powder from its neck gills and tail, knocking out prey before it can resist. Some Somnacanth sightings tell of this species making use of unusual shells, so exercise caution if you catch one swimming towards you with a shell in its claws.

Hunter tips: While in the water, it can move about as it pleases, but it doesn't fare so well on land, so draw it out to shore for an easy hunt. If you're caught in a cloud of its sleep powder, it's lights out; use a Wirebug to leap away from it and position for a counterattack.

Habitats: Frost Islands, Flooded Forest, Lava Caverns
