In this guide, we’ll tell you everything you need to know about improving the quality of your prisoners’ blood.

V Rising 1.1: Best Boss Killing BuildMay 16, 2026Irradiant Gruel can be fed to your prisoners to increase the quality of their blood by 1% or 2%! However, it also has a 35% chance to turn them into a raging mutant.
It’s a gamble, so you will mostly want to use this method on prisoners with a naturally high quality of blood. It’s much less of a risk to improve it if it’s already high!
Irradiant Gruel can be crafted at any Alchemy Station using the following materials:
- Plague Brier x15 – a new yellow flower found all over Gloomrot South. You should find it naturally as you explore Gloomrot, it doesn’t have a specific spot to find it.
- Mutant Greatse x15 – frequently found all over Gloomrot, but is most common in the Pools of Rebirth region in Gloomrot South.
When you have the materials, just head to an alchemy station and make as many Irradiant Gruels as you want.
Now just approach the prisoner whose blood quality you wish to increase and feed them the gruel. They will consume it in 3 seconds, at which point they will either get better blood or turn into a monster!
So, there you have it. That’s how you can increase the quality of your prisoners’ blood in this game! It’s a fairly big gamble, due to the relatively high 35% chance of failing, but it’s good to have the option.
