The rubble-strewn chamber is the lair of a single stirge of prodigious size—bloated to nearly the size of a half ling. Drawn to the region by the lure of the haunted chamber below, the stirge has grown large on a combination of blood and ghostly influence.

During Combat The giant stirge quickly crawls out of its nest to buzz hungrily at intruders, attacking anyone who enters its territory. If the stirge hears any form of music (such as that created by certain bardic performances or a Perform skill check), it ceases its attacks and swoops down to land next to the musician. As long as the bardic performance continues, or as long as the musician can continue to make DC 15 Perform checks (or as long as no one else attacks it), the giant stirge remains docile
Morale The giant stirge fights to the death.
A giant stirge drains blood at the end of its turn if it grapples a foe, dealing 1 point of Constitution damage. A giant stirge continues to drain blood until it has dealt 8 points of Constitution damage, then drops its prey to return to its lair to digest its meal.
