Treasure standard
The interrogators and inquisitors of devilkind, bone devils delight in
torturing those weaker than themselves—mortals, souls, and other devils
alike. Born of ancient heresies mired amid the Styx-fed swamps of
Stygia, Hell's fifth layer, bone devils—also known as osyluths—enforce
infernal order and the will of the archdevils. Powerful fiends favor
these terrifying sadists for their unwavering devotion to Hell's laws
and the commands of their masters, as osyluths eagerly report the
disobedience of other devils—regardless of standing—and take to the
craft of torture like morbid artists. Diabolists risk much to bargain
with them, as bone devils glean many infernal secrets amid their
nightmarish calcified torture hives. These devils especially delight in
journeying to the mortal plane, as their cruel talents and service to
evil spellcasters often mean gaining much valuable information, which
they might hold in their perfect memories for centuries before reporting
back to their diabolical masters.
In battle, an osyluth uses quickened invisibility after each attack to
confuse foes. Many osyluths carry twisted and eerie bone weapons, but
these tools are more for torture and intimidation than actual combat.
Osyluths tower over lesser devils at 9 feet tall—though their tails and
fearsome but useless wings make them appear much larger—and weigh upward
of 400 pounds.
