This marine-blue brute wyvern uses its saliva to prime the sticky slime coating its massive arms, rendering it highly explosive.In-game description
Brachydios is the boxer of Iceborne. This marine-blue brute wyvern coats its huge fists in sticky slime, and that slime blows up. It is a returning favorite, and in Master Rank it hits as hard as you remember.
Out in the wild
In the New World, Brachydios makes its home in the Elder’s Recess, among the crystals and lava. It keeps its arms primed by licking them, since its saliva is what makes the slime explosive. Everything it punches or stomps gets a coat of the stuff. Later on it also shows up in the Volcanic Region of the Guiding Lands.
Where you meet it
Brachydios is part of the Master Rank story. You hunt it in the Elder’s Recess in the assignment A Smashing Cross Counter. After that it is a regular target in optional quests and in the Special Arena.
How the fight goes
Expect a long, punchy fight with few safe openings. Its leaping punches close distance fast, and every hit can leave slime on you or on the ground. That slime counts down and then explodes. When it gets angry, the slime turns red much faster, so the blasts come almost right away.
Hunter’s tips
- If you get slimed, roll several times to shake it off before it goes off.
- Ice is its biggest weakness and water works well too. Leave fire at home.
- Blast Resistance helps a lot, and Earplugs deal with the roar.
- Break the head and both forelegs, and cut the tail. Pitfall and Shock Traps both work.
