Vampire heroes are immune to heart attacks due to being [[undead]] and can safely transfuse any form of blood into themselves, gain more HP from transfusion if the blood was from another vampire, and gain more nutrition if the potion used for transfusion was cursed.

 ==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]].
+{{todo|Detail more effects and other relevant details where possible.}}
 A potion of a monster's blood grants {{frac|3|10}} of that monster's nutrition value if the drinker is a [[Vampire (monster attribute)|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 automaton (starting race)|clockwork being]], [[Android]] or [[Incantifier (starting race)|incantifier]], the potion grants {{frac|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.
-The following monster types and [[monster class]]es do not have blood: all [[nonliving]] monsters, including [[golem]]s; all [[clockwork]] monsters; the [[Keter Sephiroth]]; [[mimic]]s; [[Weeping angel (dNetHack)|weeping angels]]; [[jellyfish]]; [[chorister jellies]] (including their tail segments); [[star spawn]]s; and the [[Great Cthulhu]].
+[[Thrown]] potions of blood that hit a hero or monster will not evaporate, instead covering the victim for several 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.

 Vampire heroes can use tinning kits to sustain themselves with the blood of monsters and gain intrinsics from them&mdash;incantifier heroes are only capable of eating meat from [[newt]]s and [[aoa]] (to absorb their magic), while clockwork heroes and Androids cannot eat at all, and all three very much appreciate potions of blood as a source of intrinsics.
