Characteristics
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 catch one swimming towards you with a shell in its claws.

Hunting Tips

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

Somnacanth Attack Patterns

Abnormal Breath Attack

Somnacanth's breath attacks typically inflict Sleep but can inflict a variety of other random abnormal statuses. These breath attacks have four patterns:

• Somnacanth unleashes a frontal breath attack in a straight line in front of it.
• Somnacanth unleashes a sweeping breath attack in a large cone in front of it.
• Somnacanth unleashes a massive wave of mist from its body, inflicting Sleep or other statues to anyone caught in it. This is telegraphed by the player's camera suddenly zooming out.
• Somnacanth swims around belly-up, unleashing Sleep Clouds along her path.

Rush Attacks

Somnacanth can easily rush anyone down from either its standing or four-legged positions. This attack can have two patterns:

• A quick frontal rush from the four-legged position.
• Somnacanth drums its chest from its standing position, followed by a jumping rush attack towards its target.

Swipe Attacks

Somnacanth uses its large head fins or arms to swipe a big area in front of it, inflicting heavy damage to anyone caught in it.

Shell Attacks

Somnacanth occasionally swims around belly-up while picking up a certain shell along its path. It will attempt to break the shell open by beating it on its chest, inflicting a certain effect depending on the shell it used:

• If the shell is yellow, Somnacanth will flash anyone in front in a narrow cone once it breaks.
• If the shell is red, The rock will explode in a small radius around Somnacanth once it breaks.

Flying Fins

Somnacanth has a massive tail and is capable of using it to throw several fins at the hunter for a long range attack.

How to Beat Somnacanth

Keep Out of Water

Bring Energy Drinks and Nulberries

Use Sonic Bombs to Interrupt

Keep to Its Back

Keep Out of Water

Somnacanth's rock flash and Explosion attacks occur when its on its belly-up in water. These attacks can interrupt hunters and allow Somnacanth to unleash powerful combos.

If possible, try luring Somnacanth to land using a Stinkmink or Wyvern Riding to disable these attacks completely.

Bring Energy Drinks and Nulberries

Somnacanth inflicts Sleep and other statuses with its breath. Negate this potentially deadly effect by bringing energy drinks and a bunch of nulberries!

Investing in Sleep Resistance is also worth considering when hunting Somnacanth.

Use Sonic Bombs to Interrupt

When Somnacanth coils up to perform its AoE sleep particle attack, it can be interrupted by Sonic Bombs or sonic attacks from the Hunting Horn. This creates a great window of opportunity to unleash your strongest silkbind attacks or combos.

Keep to Its Back

Somnacanth's back is exposed when ever it stands on its tail for its slam or breath attacks. Use a wiredash or dodge roll to position yourself at its back to avoid its attack or deal some damage.
