A Vaal Hazak variant encrusted with spores that spew a torrent of toxic effluvium at any who draw close.In-game description
Vaal Hazak was already creepy in World. Blackveil Vaal Hazak takes it further. This Iceborne variant is crusted with spores and wrapped in toxic effluvium, and it shows up somewhere you would never expect.
Out in the wild
Unlike the Vaal Hazak of the Rotten Vale’s depths, Blackveil also appears in the Ancient Forest. It still haunts the Rotten Vale as well. It spreads spores into its surroundings, and a thick green fog warns you that it is near. The growths on its head cover its eyes. In the Guiding Lands it lives in the Rotted Region.
Where you meet it
It is part of the Master Rank story. Reports of a Vaal Hazak outside the Vale lead you to the Ancient Forest in the assignment Under the Veil of Death. Optional quests follow.
How the fight goes
It is a slower fight, but every move spreads effluvium. It sweeps the area with beams and spits clouds of effluvium. When it rears up on its hind legs, get ready for a wide blast. Enraged, it attacks faster and more often.
Hunter’s tips
- Effluvia Resistance is the key skill. Without it, bring plenty of Nulberries.
- Fire and dragon are its weaknesses, and blast is its best status.
- Break the growths on its head. Until then, Flash Pods do nothing.
- Traps do not work on it, so leave them at home.
