Mosquito Horde

These tiny insects feed off the blood of living creatures. By themselves they are harmless, but in a large swarm, they are capable of killing full grown humans in moments.

Characteristics
The horde can cause mayhem in two ways; by draining the blood of their victims or by spreading disease.

As a creature loses blood, they become weaker, which makes the horde's job all the easier. By wearing away at a creature's constitution, the creature also has a greater chance of transmiting the diseases the horde carries. Confirmed cases include malaria.

Since they are individually weak, the most effective way to disperse the horde is to use attacks that cover a wide area.
