Dire stirges are much larger and formidable versions of the more common mosquito-like bats. Though far rarer, they too tend to live near large, stagnant water sources, are often encountered in swampy regions or dank underground caverns, and their relatively sword-like proboscis grievously impales foes and quickly drains their blood. The audible buzzing sound they make as they fly is much more pronounced than those of their smaller cousins.
