Shrieking Horrors have become a growing concern for the Drow and other creatures living below the earth. Some caverns have become clogged with these strange, reptilian, nocturnal predators.
They seem to be a fiendish dragon’s pet project, sent to destabilize the local power holders of the world below the surface and above. No one can trace their ancestry yet, but as soon as it is the dragon in question will be hunted down and exterminated for the trouble it has caused.
Combat
Shrieking Horrors tend to attack in flocks, flyby attacks with breath weapons soften opponents up for far worse. Other Shrieking Horrors in the flock follow up with spears, until the foes are ready for the kill, in which case all Shrieking Horrors leap upon one creature and claw their way to the soft center beneath.
Attach (Ex): If a Shrieking Horror hits with a touch attack, it uses its eight pincers to latch onto the opponent’s body. An attached stirge has an AC of 11.
Blood Drain (Ex): A Shrieking Horror drains blood, dealing 1d4 points of temporary Constitution damage each round it remains attached. Once it has drained 4 points of Constitution, it detaches and flies off to digest the meal.
Breath Weapon (Ex): A Shrieking Horrors can breath a cone of sound 30 ft. long dealing 4d10 damage, A reflex save DC: 19 will halve the damage. This is usable once every 1d4 rounds.
Immunities (Ex): A Shrieking Horror is immune to sleep and paralysis effects as well as damage from Sonic energy.
