Countermeasures against Blackveil Vaal Hazak

Recommended Weapon Element and Armor Skills

Fire Weapon ...and fire! Choose whichever weapon is stronger for you.

Health Boost If you cannot build Effluvial Resistance, having your health pool maxed out is indispensable.
Earplugs Blackveil Vaal Hazak has a big roar, so getting Earplugs Lvl 5 would be immensely helpful.
