Combat:
Bainligors hunt and see via echolocation just as their normal bat counterparts.  They are completely unaffected by darkness 15’ radius, invisibility, and blindness spells and all visual illusions.  They attack with shear numbers, overpowering most foes easily.  While smaller bainligor inflict only 1d4 points of damage with their claws and teeth, bainligors of 4th to 9th level inflict 1d6 damage, and the elders and Revered Ones inflict 1d10 damage.  Deafness spells cause the creatures to act as if they were blinded.
	Bainligor figure their jumping distances as if their Strength scores are 18 instead of 10.
	Bainligor can use their echolocation as a weapon.  Once per hour, a bainligor can emit a burst of ultrasonic sound that hammer flesh like a gigantic fist.  This attack replaces all others and does 1d6 points of damage per HD.  A target creature must pass a Fort save (DC 11 base) or become deafened and stunned for 1d4 rounds (-2 AC and no Dex bonus, plus he cannot attack and may only move at ½ speed at a walk).  Those failing the save by 8 or more are permanently deafened.

Characters:
Bainligor have a preferred multiclass of fighter, though there have been several monk bainligor (obvious shift in alignment) and many clerics as well.

Revered One
Revered Ones are at least level 10 bainligor that have gone off into seclusion and come back as an undead.  Their Strength scores are increased by 4, plus they receive all the benefits and penalties of being undead.  Many Revered Ones have several levels of cleric, and some are even wizards or sorcerors (and use the lich template).  They are always followed by many fanatically loyal lesser bainligors.
