Vile Weather

Vile Weather

The infamous Book of Vile Darkness includes several new types of vile weather. I've always liked supernatural weather effects.

Violet Rain: Always accompanied by a terrible thunderstorm filled with lightning, violet rain brings portents of great evil. Once violet rain begins to fall, all connection with divine agencies is severed for 24 hours. Divine spellcasters have no access to spells, divine spell effects are suppressed, and divinely infused magic items cease to function. A typical violet rainstorm covers 1d×200 square miles. Other effects are identical to normal rain.

Green Fog: Clouds of dark greenish mist roll across the countryside. Any living creature touched by the mist must make HT+2 checks every 5 minutes or become permanently polymorphed into a random creature (use a random table, or select a creature from a relevant wilderness encounter list). The fog usually encompasses an area of 1d/2 square miles, lasts for 10d minutes, and moves at a speed of 3 yards per second.

Plague of Nettles: Tiny organic thorns fall from the sky. Those caught in this brief rainfall take 1d-4 small piercing of damage each second, unless they can get under some sort of shelter. The nettles that strike soil burrow into the ground and sprout thick, choking weeds that kill whole crops in a few minutes. A plague of nettles is violent enough to tear up and choke a forest in just a day. One week after the nettles fall, the area is thick with animate, dangerous plants such as assassin vines, tendriculoses, and shambling mounds. This malevolent rainfall spreads across 3d square miles and lasts for 1dx10 seconds.

Rain of Blood: This horrible event can occur as part of a regular thunderstorm or all on its own. Blood pours down in thick drops for 3d minutes, coating everything in a dark red, sticky mess. A rain of blood covers 5d square miles. Other effects are identical to normal rain.

Rain of Frogs or Fish: This preternatural rain deals 1d-4 crushing damage per second to anyone not under shelter. The thousands of animals that fall from the sky usually die from the impact. The rain lasts 8d seconds and covers an area of 2d square miles.
