CONSUME

Help Consume

Syntax: consume

The consume command is used by vampires to drain blood from the corpses of
their victims, which will in turn restore some of their hit points. 
Stronger and tougher mobs naturally provide a more filling, and thus more
rejuvenating, meal...

Be warned that consuming a corpse has the same effect as sacrificing it- 
any items in the corpse are lost.  '
Consume' will eat all corpses in the
current room.  Vampires may choose between automatically consuming and
sacrificing corpses; see '
help autoconsume'.
