Stirge (Basic Lore)

Stirge (CR 1)
Neutral - Tiny - Vermin
This strange creature looks like a mosquito that ate a demonic housecat. It's got four wings, numerous spiny legs and a long proboscis through which they drain the blood of their prey. They lurk in caves and ruins, and are rarely encountered alone. They tend to gather in large flocks and can completely drain a human-sized victim in minutes. Stirges drink blood, much like large horrible mosquitoes, and while they are mainly a pest for experienced adventurers, they are a deadly peril for the less martially inclined. Any sighting of a stirge nest close to a community is cause for every adventurer to go and clean it out, before a tragedy strikes.
