How to Defeat Aurora Somnacanth in Monster Hunter Rise Sunbreak

This section will walk you through the strategy for defeating Aurora Somnacanth, so let’s get right to it.

Lure it to Land

In order to lure Somnacanth to land, you can rely on a Stinkmink or Wyvern Riding. This will give you a significant advantage upfront in the fight.

Energy Drinks and Nulberries

When you start your hunt for Aurora Somnacanth in MHR, it’s a good idea to invest in Sleep Resistance. As aforementioned, Somnacanth can inflict sleep with its breath, which can prove fatal.

To nullify the effects of this potent attack, it is recommended to have an ample supply of Energy Drinks and Nulberries.

Use of Sonic Bombs

The sleep attacks will cause you the most trouble in this fight! So, in order to tackle that problem, it is also a good idea to use Sonic Bombs or sonic attacks from the Hunting Horn, since they can interrupt the sleep attacks.

Not only that, after the use of Sonic Bombs, you’ll have a small opening to counter-attack, so make it count.

Position Yourself at its Back

Somnacanth every now and then stands on its tail either to unleash its tail slam or the devastating breath attacks. No matter the attack, this opens an opportunity for you to counter.

All you need is to position yourself at its back and it’ll do the trick. This will avoid the damage from the upcoming attacks as well as open the opportunity for counter-attacks. A Win-Win Scenario!
