3-12 is for a weapon specific to the Bone Devil, the Bone
Hook. It should be considered at 18.00 for the purpose of grasping.
Those “stuck fast” in the hook can try to break it (Strength of at least
18.00 required) or hit the Devil at -4. The Devil will teleport only after
hitting the victim with its tail at least once. If the Hook is lost then the
Devil will do 2-8/2-8 damage from claws. Its opponent, though better
held by its claws if both hit, can still strike at only -2.>

Bone devils populate the lower planes of Hell, particularly the fifth. They
are particularly malicious and delight in making less powerful treatures
suffer. As they prefer cold to heat, these monsters also have ultravision,
seeing light in the ultra-violet spectrum at 60' range. <color>

Bone devils have a great bane hook they employ to snare and wound
opponents. Any creature caught (hit) by it has a 50% chance of being stuck
fast. The bone devil will then strike such victims with its tail doing 2-8 hit
points of damage, plus causing a loss of strength (1-4 points) unless a save
versus poison is made; strength loss lasts for 10 melee rounds.

At will, once per turn or melee round, as applicable, bone devils can:
generate fear in a 5' radius sphere, create illusion, fly, become invisible,
detect invisible, fear (spell), or summon another bone devil (40% chance
of success). Once per day it is able to create a wall of ice.
