Bloodfiend's Curse

The Bloodfiend's curse is the result of tampering with any potion created in the Barrel of the Faithful. When any substance is tainted by even a small drop of blood, the whole contents will be turned into the Bloodfiend's Curse while still turning close to the color of the original potion.
Any Potion tainted by blood additionally increases the longevity and strength of the consumer for a large span of time.

Side Effect

Even the smallest amount consumed will lead to a strong addiction to this potion. Repeated consumption will lead to strongly diminishing returns as will any potion with the own drinker's blood. Failure to regularly consume can lead to strong incapacitation and even death.
