I think tghe hyads could use a slightly more focused description. Not all fey women should be described as "elven." It's really overused. The call rain should match the rain description in the SRD. There are really good weather rules already.


A hyad is a Fey creature with translucent pearly skin, light blue lips, and long curly dark hair that waves of its own accord, even when there is no breeze. Hyads are known for their lush gardens, and for caring for Plant creatures, especially carnivorous ones such as Shambling Mounds, Giant Sundews, and Giant Venus Flytraps. While they are well known for their ability to call rain, they are loathe to do so unless directly benefits the plants they care for.


Call Rain (Su): Three times a day as a standard action, a hyad may cause rain to fall for 2d8 minutes. Rain reduces visibility ranges by half, resulting in a -4 penalty on Spot and Search checks. It has the same effect on flames, ranged weapon attacks, and Listen checks as severe wind. Rain that lasts more than two hours has the potential to cause flooding.

Call Thunderstorm (Su): Once a day as a standard action, a hyad may cause a thunderstorm to appear for 1d4 hours. In addition to wind and precipitation (usually rain, but sometimes also hail), thunderstorms are accompanied by lightning that can pose a hazard to characters without proper shelter (especially those in metal armor). As a rule of thumb, assume one bolt per minute for a 1-hour period at the center of the storm. Each bolt causes electricity damage equal to 1d10 eight-sided dice. One in ten thunderstorms is accompanied by a tornado.

Call Severe Storm (Su): Once a week as a full action, a hyad may cause a severe storm to appear for 1 hour. Very high winds and torrential precipitation reduce visibility to zero, making Spot, Search, and Listen checks and all ranged weapon attacks impossible. Unprotected flames are automatically extinguished, and protected flames have a 75% chance of being doused. Creatures caught in the area must make a DC 20 Fortitude save or face the effects based on the size of the creature:

Tiny and smaller creatures are Blown away. Creatures on the ground are knocked prone and rolled 1d4×10 feet, taking 1d4 points of nonlethal damage per 10 feet. Flying creatures are blown back 2d6×10 feet and take 2d6 points of nonlethal damage due to battering and buffeting.

Small creatures are knocked prone by the force of the wind. Flying creatures are instead blown back 1d6×10 feet.

Medium creatures are Checked. Creatures on the ground are unable to move forward against the force of the wind. Flying creatures are blown back 1d6×5 feet.

I hope this helps.
