Right. Let's stick with the plain ol' verminous variety.
Humbug! Lolth is the Demon Queen of Spiders so they ought to be Demon Spiders.
Well I wasn't
entirely serious about the suggestion, so Vermin it is then.
Getting back to the Awe, we've currently got something like:
Awe (Su): Once a minute, a drow vampire may create an aura that can deeply affect mortals. It does this merely by making some dramatic gesture, such as baring its fangs or letting out a commanding cry. Creatures that can see the drow vampire must succeed on a DC X Will save to avoid the effects. A creature that succeeds on its saving throw becomes immune to that vampire's awe for 24 hours. This awe is a mind-affecting effect that lasts for 2d4 rounds. The save DC is Charisma-based.
A drow vampire can choose either of the following effects each round as a free action while its awe power is in effect:
Daze: Affected beings just stare at the drow vampire in fascination. Awed creatures may defend themselves normally, but can take no actions. If a creature is attacked physically, it will recover in the following round.
Fright: Affected beings become shaken and suffer a –2 morale penalty on attack rolls, saves, and checks. The merest glance or gesture from the drow vampire makes them frightened, and they flee as quickly as they can, although they can choose the path of their flight.
