Stirge

Actions

Blood Drain: Melee Weapon Attack: +5 to hit, reach 5 ft., one creature. Hit: 5 1d4+3 piercing damage, and the stirge attaches to the target. While attached, the stirge doesn't attack. Instead, at the start of each of the stirge's turns, the target loses 5 1d4+3 hit points due to blood loss. The stirge can detach itself by spending 5 feet of its movement. It does so after it drains 10 hit points from the target or the target dies. A creature, including the target, can use its action to detach the stirge.

This horrid flying creature looks like a cross between a large bat and an oversized mosquito. Its legs end in sharp pincers, and its long, needle-like proboscis slashes the air as it seeks its next meal. Stirges feed on the blood of living creatures, attaching and draining them slowly. Although they pose little danger in small numbers, packs of stirges can be a formidable threat, reattaching as quickly as their weakening prey can pluck them off.   Blood Drain. A stirge attacks by landing on a victim finding a vulnerable spot, and plunging its proboscis into the flesh while using its pincer legs to latch on to the victim. Once the stirge has sated itself, it detaches and flies off to digest its meal.   Stirges are the adult form of rot grubs. After consuming a great deal of flesh, and ensuring that it itself will not be consumed by a swarm of other rot grubs the rot grub cacoons itself in a hardened shell until it is ready to emerge as a fully grown stirge.

Stirges seek out areas with large populations. They aren't picky about who's blood they drain but will avoid places where they are attacked or where their victims put up a strong defense. They also tend to roost either in trees or caves where they can hide during the day. They are usually nocturnal.
