A whining, swirling fog of dust mote-sized insects hovers around you, scenting your blood.

A mosquito swarm is a cloud of tens of thousands of winged vermin which drains
warm-blooded creatures of blood in order to fuel their reproductive cycle.

Combat
A mosquito swarm surrounds and attacks any warm-blooded prey it encounters. A
swarm deals 1 point of non-lethal damage to any creature whose space it
occupies at the end of its move, often spreading disease in addition to its
painful bites.

Distraction (Ex): Any living creature that begins its turn with a mosquito swarm
in its space must succeed on a DC 10 Fortitude save or be nauseated for 1 round.
The save DC is Constitution-based.

Disease (Ex): A mosquito swarm may carry any of the following diseases, depending
which is most appropriate for the terrain and climate in which it lives.

* Brain fire—swarm attack, Fortitude DC 10, incubation period 1d3 days, damage
1d2 Con and 1d3 Wis. The save DC is Constitution-based and includes a +2 racial
bonus.

* Malaria—swarm attack, Fortitude DC 12, incubation period 1d6+5 days, damage
1d2 Str, 1d3 Con, and 1d2 Wis. The save DC is Constitution-based and includes
a +2 racial bonus.

* Yellow fever—swarm attack, Fortitude DC 14, incubation period 3d2 days, damage 1d3 Str, 1d3 Dex, and 1d4 Con. The save DC is Constitution-based and includes a +4 racial bonus.

Any mosquito swarm may carry brain fire. Malaria is limited to temperate and warm regions. Yellow fever is limited to temperate and warm marshes, and to warm forests.

Skills: A mosquito swarm has a +4 racial bonus on Listen and Spot checks.
