A vile plague spread through infected corvids – crows, jackdaws, bluejays, and their ilk. Those afflicted experience high fevers, violent coughs, fluid-filled lungs, discoloration of the face and chest, and extreme fatigue.

The Plague causes a variety of potentially deadly bodily responses, most of which can be mitigated with common remedies and treatments if given proper attention, but too often such aid is unavailable or inadequate to stave off the symptoms. Birds carrying the disease are easily spotted – their 6 plumage and behavior is obviously that of a sick bird, but some places are so fearful of the Corvid Plague that they resort to wholesale slaughter of such birds upon sighting. For what it may be worth, this preventative treatment works, and the birds tend to stay away (healthy or not) after purges, whatever external consequences that may bring to the local environment.

Survivors of this Plague are often rewarded with a lifetime cough from the internal damage it caused – better than death, but there are tragically comical tales of remote villages that survived an outbreak being quite noisy places to visit, with an ever-present cacophony of hacking and wheezing. A humanoid or bird exposed to an infected creature, such as by proximity, must succeed in a DC 15 Constitution save or also be infected. A creature so infected must succeed in a DC 20 Constitution save each day or take (Character Level+1)d6 of damage as the disease ravages their body.

Kenku take double damage. During this time, an infected creature cannot recover hitpoints through natural means. The disease fades after 1d6 days, though creatures remain infectious for 1d6 days after that.

Diligent care by another through a DC 15 Medicine skill check can suppress all symptoms for a day, but such a check can only eb attempted once per day.
