A monster that scavenges for meals dropped from the Coral Highlands. It acts as the alpha leader of a Girros pack, and sports giant fangs that paralyze its prey.In-game description
Great Girros is the boss of the Rotten Vale’s scavenger gang. It isn’t the biggest monster down there, but one bite from those huge fangs can leave you frozen in place while the whole pack piles on. In World and Iceborne it is a classic lesson in why you never ignore the small fry.
Out in the wild
It lives in the Rotten Vale and feeds on whatever falls down from the Coral Highlands above. Great Girros leads a pack of regular Girros as their alpha, and the pack hunts together. Its lower haunts are full of effluvium, the toxic haze that slowly drains your health.
Where you meet it
Great Girros isn’t a story target. Its first dedicated hunt is the optional 4-star Low Rank quest A Rotten Thing To Do. It returns in High Rank and in Iceborne’s Master Rank.
How the fight goes
Everything revolves around paralysis. Great Girros bites, lunges and snaps its jaws, and it can paralyze you both up close and from a distance. It also calls in its Girros, and they can paralyze you too. Being stuck is the dangerous part, since it leaves you open to whatever comes next.
Hunter’s tips
- Take out the smaller Girros first. With the pack gone, the fight gets much calmer.
- Break the fangs. It weakens its paralyzing bite a lot.
- Use Water first, with Fire and Ice as good backups. Sleep works great on it, but paralysis barely does.
- Effluvial Expert helps against the Vale’s haze, and Paralysis Resistance takes away its main weapon.
