| A potion containing the essence of life. Vital for all living creatures, as well as some undead ones. |
Quaffing a potion of blood provides the user with X nutrition. However, unless you have the carnivore or gourmand traits, there is a chance that you will instead become sick:
Sick Chance: 25 + (25 x Ranks of Herbivore)%
Alternatively, you may wield a potion of blood to fuel a casting of Sublimation of Blood.
After 2,000 turns have passed, a potion of blood will degrade into a potion of coagulated blood. These are similar in nature, but worth X less nutrition and will rot away entirely in another 500 turns. The game tracks the freshness of each potion of blood even though they're stacked together into one inventory slot.
Normally, players will only find potions of blood as loot on vampiric opponents. At level 6, however, vampires gain the ability to extract potions of blood from corpses. The number of potions extracted is dependent on the monster's body weight, while their freshness depends on how quickly you bottle them (each turn since the monster was killed counts as 10 turns spent bottled).
Followers of Zin, Elyvilon, and the Shining One incur a piety loss if they knowingly drink this potion; followers of the Shining One also incur a penance.
Potions of blood are automatically identified on sight.
Vampires: "Yummy - fresh blood!"
Carnivores: "This tastes like blood."
Others: "Yuck - this tastes like blood"
History
In 0.15, ghouls can restore a single point of rot by quaffing a potion of blood.
Prior to 0.14, potions of blood were capable of generating randomly, and would restore much more nutrition to vampires than to other species. Also, they were unidentified by default, but having one in your possession when it coagulated would identify both forms. As these potions were always red, it was generally easy to guess their identity anyway.
