V Rising - Making Dracula Blood Exploiters Quit the Server

This clan have been using Dracula's Immortal Blood on so many occasions: rifts, open world pvp or defending a raid. Around 5 minutes before this raid happened, both of these defenders have the dracula blood and been casting unlimited void to kill everyone, it's just unfortunate that I was not recording. SLS said they are aware of the bug. I've reported them days before this raid but they're still not banned.

This blood is very very overpowered:
50% chance to reset spell cooldown on cast
40% damage reduction
100% veil cooldown recovery rate
30% primary attack speed bonus
15% movement speed bonus
100% physical power and spell power bonus

If used well, you can really be unkillable. They use an in-game exploit to get this blood out to the open world which is really easy to do but please don't ask me, I won't tell.
