Nupperibos exist by the hundreds of thousands throughout the hells.
They are the remains of all lawful evil creatures not sufficiently malignant
to be changed into lemures (q.v.). They are blind, deaf, and unable
to speak. They are sensitive to mental commands from stronger devils,
andthey alsosensethe presence of their own kind.They readily obey all
commands in order to lessen the pain and torment which is the normal
lot in the Infernal Region. The normal attack mode of a nupperibo is 2
clawing rakes with its hands. However, when an infernal army is
gathered, each member is given some sort of weapon-usually a club,
spear, or polearm. The creatures then march and attack blindly but with
effect because of the vast numbers gathered into legions and directed by
more powerful devils. (Note that, if uncommanded, the hordes of nupperibos
will continue to march and attack all things not of the Nine Hells.)

In the Infernal Region or areas of total Evil, nupperibos regenerate at 1
hit point per round, but elsewhere this power is lost. If a holy object
(water, weapon) is used against them, regeneration is not possible.
Nupperibos which are slain in the cause of evil are 99% likely to be
re-formed as Nupperibos. There is, however, a 1 %chance that they will
be re-formed as lemures of a special sort. These special lemures are
those from which the lesser devils are formed. One spending a mere
millennium of time as one of these lemures might attain devilhood.

Because of the limited sensory capabilities of nupperibos, no intelligence,
per se, can be assigned them. The possible range, were their
status changed, would vary from semi- to exceptionally intelligent.
