Lavasioths utilize molten lava as armor. They are extremely aggressive and will attack without prejudice until the threat has been eliminated.In-game description
Lavasioth is a fish that swims in lava. That alone makes it one of the stranger hunts in World, and its magma armor makes it one of the more stubborn ones too.
Out in the wild
This Piscine Wyvern lives in the Elder’s Recess, where it glides through the molten lava pools like they were water. It wears the lava as armor: fresh from a swim, its body is coated in soft magma, and once it is out in the air that coating cools and hardens. It is very aggressive and keeps attacking until whatever bothered it is gone. Uragaan is known to clash with it over territory.
Where you meet it
Lavasioth is a High Rank monster with no Low Rank version. After you spot it on a High Rank quest or expedition, the optional 7-star quest Lavasioth, Monster of Magma opens up in the Elder’s Recess. It is also a quest target in Master Rank in Iceborne.
How the fight goes
The fight is a rhythm. Lavasioth dives into lava, then climbs back out with a soft coat that is easy to cut. Hit it hard right then, before the armor turns black and hard again. Its biggest attack is a large lava ball. Watch for it tilting its head back, then run or roll to its side.
Hunter’s tips
- Water is the weakness that always works. Once the armor has hardened, Thunder and Ice lose most of their punch.
- Torch Pods soften the hardened magma, so you don’t have to wait for it to swim again.
- Aim for the head and the belly, which stay softer than the armored back and tail.
- Bring Nulberries or good Fire Resistance for Fireblight, and Tremor Resistance helps when it shakes the ground.
