From publisher blurb:
Letters from the Flaming Crab is a monthly series of Pathfinder-compatible supplements. Each Letter focuses on exploring a different topic to give gamemasters and players new, exciting options that can be dropped into any campaign.
Within Strange Weather...
We bring you a dozen new Conditions and Hazards more magical and exciting than a mere thunderstorm! Acid rain, aurora hypnosis, ball lightning, blood storm, ectoplasmic storm, fire whirl, hailstorm, pollen storm, skyquake, blood moon, dread moon, radiant moon, and the solar eclipse!
We also introduce the Storm Elemental with four variants: the blizzard storm elemental, dust storm elemental, hurricane elemental, and lightning storm elemental!
And we finish Strange Weather with two weather related archetypes: the Stormcaller (Shaman) and the Child of the Sky (Barbarian)!
