Weather stone

The Weather Stone is an object which requires two expansion packs from The Sims 3 which are Supernatural and Seasons. The four occults included in Supernatural can use it, with their own abilities, to cast a weather effect.

Location
If both of the packs are installed, the weather stone will be automatically placed in a lot from a town once a save is loaded or created via a pop-out notification. The notification tells that the weather stone is successfully installed in the game and it includes "View Weather Stone Location" which locates the weather stone in the town.

The location of the weather stone changes in the town when a save is loaded, but there is a possibility that it will appear on the same location twice.

It cannot be found on Buy mode, so it could not be placed on any lots.

Bewitching Rain
This can be summoned only by witches.

"When a witch casts this mischievous spell using the weather stone, a green rain will fall on the entire world. Any Sim caught outdoors will dance wildly and act crazy, even though they are magically prevented from getting wet!"

Eclipsing Fog
This can be summoned only by vampires.

"Vampires can conjure this spell to cause a chilly fog to form over the town and cool even the hottest summer day. It also makes it easier for your fanged friends to find willing snacks."

Reviving Sprinkle
This can be summoned only by fairies.

"Who says rainy days have to be dreary? When fairies create this spring shower of blossoms, all the gardens in the Sims’ world are instantly revived and cared for. Of course, no fairy magic would be complete without a rainbow at the end!"

Hunter's Storm
This can be summoned only by werewolves.

"Werewolves are great hunters to begin with, but this magical storm gives them even more of an edge. Collectable items fall with the snow and your lupine Sims have a much better chance of sniffing them out as they stalk through the icy drifts."
