Greater Yugoloth
These yugoloths are dispatched only to protect objects of exceedingly great value. Greater yugoloth guardians are resistant to magic (25%) and are always immune to two additional forms of attack. They can make a suggestion, as the spell, once per round, even when engaged in combat.
Greater yugoloth guardians always appear as gigantic, winged bears with ram horns protruding from their foreheads, and eagle talons for hands.
