This magical horn, which looks like any of the others, when
sounded will bring forth 1-4 Lesser Devils or 1 Greater Devil. The Devil
will obey the commands of the horn holder for 1-6 hours but has free
will if he is attacked or if he is asked to give over any treasure he may
carry. For a Good Cleric or a Paladin to command a devil to service will
require an ATONEMENT, though they may give the horn to the devil
and command it to be gone. The Devil will bear the holder no ill will and
will perform the required task — though he may require a cut of the
profits (60% likely for a lesser devil, 90% likely for a greater devil). The
Horn can only be sounded once by any one character. Sounding the
same horn a second time will bring an Arch Devil who will take the horn
and its holder straight to Hell for torture and removal of his/her soul.
