A grotesque elder dragon that inhabits the deepest part of the Rotten Vale. It uses the fatal vapor of the vale in what appears to be a symbiotic relationship.In-game description
Vaal Hazak is the stuff of nightmares: a pale elder dragon draped in rotting flesh that breathes death itself. It is one of World’s most original creations, and a hunt you won’t forget.
Out in the wild
It lives in the deepest part of the Rotten Vale, near its lair at the bottom of the map. Vaal Hazak lives with the vale’s deadly vapor in a symbiotic way, soaking it up and spreading it. The air around it is thick with effluvium, and the acid pools nearby make that bad situation even worse.
Where you meet it
You meet it in High Rank, in the 8-star story assignment Hellish Fiend Vaal Hazak. A tempered version shows up later in High Rank. Iceborne has its own Blackveil Vaal Hazak, which gets a separate page.
How the fight goes
Its attacks are slow and readable, but they hit hard. The real danger is effluvia, which cuts your health bar in half. Its signature move is a huge effluvium beam that reaches across the area. In a group, it likes to aim that beam at whoever wanders away from everyone else.
Hunter’s tips
- Bring plenty of Nulberries to clear effluvia and get your full health back.
- Shoot the two fangs hanging over its lair with your slinger to drop it on the ground.
- Fire is its best weakness. Dragon only works well on wounded parts.
- Stay on its sides, and in multiplayer stick close to your team so the beam is easier to avoid.
