What are Somnacanth weaknesses, resistances, & drops | Monster Hunter Rise

Quite the slippery Leviathan.

Monster Hunter Rise offers players the chance to tackle a horde of enemies from various biomes and areas. There are dozens of towering giants for hunters to track and defeat across the game's campaign. One of the adversaries must beat the Somnacanth, a Leviathan that lurks in lakes and rivers. This serpent could spell the end for an unprepared team, so make sure you've studied up on your prey before heading out to the field. Here are Somnacanth's weaknesses, resistances, and drop rates.

All Somnacanth Weaknesses

Somnacanth Elemental Weakness

The Somnacanth's main weakness is thunder, so make sure to bring a weapon infused with this element for the highest damage output. If you lack a thunder weapon, be sure to pick up a fire weapon instead, as this is a solid second option. The beast is immune to several elements, so do not use water, ice, or dragon weapons on Somnacanth.

If you brought elemental weapons to fight the Somnacanth, focus your attacks on its Head, Neck, Hind Leg, and Tail when battling. Attacking these areas yields the highest damage output.

Somnacanth Location Weakness

If you are not wielding an elemental weapon, you want to attack places where you deal extra damage. These places on a monster differentiate depending on the weapon type you use—Cutting, Impact, or Shot.

Hind Leg253025
  • If using a cutting weapon focus on the head and neck.
  • If using a blunt weapon focus on the neck.
  • If using a bow/shot weapon focus on shooting the neck.

Somnacanth Resistances and Ailments

Few ailments deal substantial damage to Somnacanth, but Blast and Thunderblight are excellent options should you have weaponry with these effects. Make sure to attack quickly and impact the beast with ailments to chip away at its health and stamina. The Somnacanth has no Ailment resistances, but all other ailments are slightly effective on this Leviathan.

Somnacanth Drop Rates - Carves, Capturing & Breaking

Depending on your quest, you can get different rewards to forge armor and weapons, but each has a drop rate percentage, ultimately RNG. It is pure luck what you receive.

  • There are multiple ways of gaining items
    • You can carving three times once the monster is dead.
    • You can capture the monster instead of killing it.
      • Or carving the broken appendage of said monster.
    • From looting the drops from the monster
    • After successfully compleing your quest

Most monsters have breakable parts, and Somnacanth is no different. The Head Fin, Foreleg, and Tail will all break with enough pressure. If you shatter these pieces during the hunt, you will earn extra rewards after completing the quest.

About the Author

Hey, my name is Mark, and I'm a video game enthusiast! My earliest memory was playing Worms on the Amiga against my Godmother, yes the Amiga, massive box type thing, needed eighty-five thousand floppy disks to play one game, maybe a slight exaggeration. Ah, those were the days! I love RPG’s, and The Legend of Zelda series. Dogs are pretty awesome.
