PFS StandardFen Mosquito Swarm

When deadly fen mosquitoes gather in large numbers, they form into lethal swarms capable of draining blood at a truly alarming rate. Fen mosquito swarms are typically encountered only in tropical swamps or bogs, but during humid months in spring or summer they can drift into riverine areas or even through the waterfront reaches of settlements.

Mosquito

While the common mosquito is a pest capable of spreading deadly diseases, their giant kin and the ravenous clouds of mosquito swarms are even more dangerous.

Sidebar - Advice and Rules Malaria Strains

This pernicious disease is often associated with mosquitoes. The most common version of malaria is presented in the Pathfinder Gamemastery Guide, and while the variants inflicted by mosquito swarms and giant mosquitoes are deadlier, they don't have the chance to recur after 1d4 months. Pyrexic malaria also causes weakness and fevers, while septic malaria causes painful and infected lesions to form on the body. Regardless of the strain you contract, you can't reduce your sickened condition while you are affected with malaria.
