A potion of blood is a type of potion that appears in dNetHack, notdNetHack and notnotdNetHack. It appears as a blood-red potion when unidentified, and contains the blood of a specific monster that is revealed when the potion is identified, similar to a tin.
Generation
Potions of blood make up 1.8% of all randomly-generated potions.
Vampire heroes start with knowledge of the potion of blood, and will be given human blood as a replacement for the following items in their role's starting inventory: food rations, cram rations, potions of fruit juice, tripe rations, bananas, oranges, and potions of booze.
Applying a tinning kit to the corpse of a monster that has blood will always produce an identified potion of that monster's blood alongside a tin of their flesh or matter.
All vampires have a 2⁄3 chance of generating with at least one potion of blood from a random appropriate monster - they may carry anywhere from one to four potions, with an equal chance of each quantity.

Description
Quaffing a potion of blood prints a message describing what monster's blood it smells like if the hero is a vampire or any non-herbivorous race, and then gives the player a yes/no prompt for drinking it. The nutrition, intrinsic properties and other effects of a monster's blood generally depend on those of that monster's corpse, the monster drinking the blood, and the potion's beatitude.
A potion of a monster's blood grants 3⁄10 of that monster's nutrition value if the drinker is a vampire quaffing a cursed potion, or if they are in the form of a non-herbivorous monster and quaffing a blessed potion. Otherwise, if the drinker is not a clockwork being, Android or incantifier, the potion grants 1⁄5 of that monster's nutrition value. A hero that drinks blood and is not a clockwork being, android, incantifier, or vampire will become nauseous for 10d8 (more) turns.
A monster's blood has the same properties as its corpse: a monster whose corpse is poisonous to eat has poisonous blood, while an acidic monster has acidic blood, a monster whose corpse causes stoning has blood that causes stoning, and so on. Intrinsics granted by a monster's corpse are also granted by that monster's blood, regardless of whether or not the drinker gains any nutrition from consuming blood and can do so without nausea. A hero quaffing the blood of a same-race monster is penalized for cannibalism as if they had eaten that monster's corpse.
In addition to the above, certain types of blood have special effects when quaffed or utilized in alchemy.

Strategy
Vampire heroes can use tinning kits to sustain themselves with the blood of monsters and gain intrinsics from them—incantifier heroes are only capable of eating meat from newts and aoa (to absorb their magic), while clockwork heroes and Androids cannot eat at all, and all three appreciate potions of blood as a source of intrinsics. Other races can simply dilute the potions for water.
