Monster Information

Blackveil Vaal Hazak

blackveil vaal hazak re2.png

Instead of giving you Effluvial Buildup, Blackveil Vaal Hazak will give you the Zombified status, making the Effluvia Resistance skill useless.

The Zombified status will make you slower and unable to heal with normal healing items, but you do regenerate health passively. Cure yourself through green herbs and red herbs!

Rewards

Full Armor Sets

Leon α+ and Claire α+ armor sets.png
You can get the Leon α+ and Claire α+ armor sets, both of which have Zombie & Effluvia Res. Useful if you want to do the quest again and again, or if you just want to beat up a normal Blackveil Vaal Hazak in style.

Pendants

You can get flashy pendants that either represent the R.P.D., the Umbrella Corporation, or a random tofu.

Gesture: Zombify

If you ever wanted to get the zombie look without carrying the effects of being zombified, this gesture has got you covered.

Gesture: Zombie Bite

Ever seen a gesture that can do damage to monster before? Well, now you have. It does even more damage if you are zombified.

Room Decor

Match your room with the Raccoon Police Station. Your item box's look is changed to match the one in the Resident Evil 2 game, and you can even have a typewriter that you can save your game in.

Guild Card

Additionally, you will also get extra content for your guild card, such as a background, two poses, an expression, and five titles.
