Fairy

Fairies are a playable life state that are introduced in The Sims 3: Supernatural. (Technically, Faerie Queen Mara, an NPC vendor from The Sims: Makin' Magic, was a fairy, but Fairy was not a playable life state.) Fairies first appeared in the official announcement trailer for the expansion. Before they were officially announced, there was a patch (1.32) which accidentally leaked visual effects files of fairy wings.

Overview
Fairies are described as elegant but mischievous magical creatures who love playing tricks on Sims, and who maintain their basic needs just like normal Sims. They have a hidden skill known as Fairy Magic.

Ways to make a Fairy

 * Create a Fairy in Create a Sim. See Creating a Fairy section below for more information.
 * A Sim can become a fairy by getting a chance to receive a Fairy opportunity when searching for fairies in the Arboretum.
 * There is a elixir known as the Bottled Blessing of the Fae which can turn a normal Sim into a fairy.
 * A Sim with level 10 of Alchemy skill can mix this elixir at the alchemy station by having red toadstools, sunstone gem and fairy damsel in his inventory.
 * Check an elixir consignment shop as the shop may have the elixir, but not on a daily basis.

Abilities
Fairies live longer than normal Sims just like werewolves and vampires. They move at an increased rate as they fly around. They shrink to their natural form to perform interactions that they can't do when normal-sized. They are "natural born tricksters", tricking Sims using different interactions.

They have the Green Thumb trait by nature - meaning that they have benefits similar to the benefits Sims with the trait should have, without having it in their traits. However, they cannot revive dead plants, despite having this trait.

They can build their Charisma skill at a faster rate.

The more they use magic, the more abilities become available. They can receive different auras, and the ability to use fairy pranks.

Underneath the full moon they get the moodlet 'energized by the moonlight,' and under the new moon they get 'starving for moonlight.'

Magic
Fairies are able to use magic for good or bad. When starting out, they will have a very limited set of magical abilities. As they gain their Fairy Magic skill, they unlock new abilities and benefits slowly.

Magic is not infinite, so when fairies use magic, they begin to lose magic powers. They have a magic meter which is similar to the meter witches have. The meter can be found under a fairy's avatar in the game interface. The meter shows how much magic power they have left.

As their magic powers drain, fairies should maintain the magic meter in order to continuously use their abilities. They can slowly wait for a while to refill the meter or they can fill their meter at a faster rate by drinking Pollen Punch, riding the train in a train set or relaxing in a Fairy House. They can also instantly replenish their meter to full by drinking the Essence of Magic elixir.

If all of their magic power is used up, it will take normally six hours to refill completely, enabling them to use magic again. During these six hours, they will have a negative moodlet.

Although fairies are "natural born tricksters", not every trick will be successful. Sometimes, their tricks will fail, causing some negative effect to either the fairy, the affected Sims, or both.

Fairies use auras which affect themselves and nearby Sims. There are several different auras, which have different effects. Some of these are:
 * Aura of Soothing - Gives a positive moodlet
 * Aura of Creativity - Creative skills are easier to learn, and are learned faster
 * Aura of Body and Mind - Improves the rate at which Sims learn skills related to body or mind

If Seasons is also installed, fairies can cast Reviving Sprinkle using the Weather Stone, which turns rain into flowers. All the gardens in the current world will be magically watered and fertilized, vanishing weeds off and revived dead plants. At the end of Reviving Sprinkle, a beautiful rainbow can be seen across the sky.

Interactions
Since fairies love to trick, they can do so with the available interactions, depending on what Fairy Magic level they are on. This may reduce Sims' relationship with the fairy.
 * To Sims

But fairies can also be on the good side. In addition to their auras, they can use the Playful Pester interaction, in which a fairy playfully circles the head of a Sim in their natural form. This boosts social and fun motives for both the Fairy and Sim.

Fairies can give their fairy dust to Sims which can be used to remove the zombie's curse or give another Sim the ability to float.

Fairies can also play round by the Fairy Frolic interaction. Similar to the Playful Pester interaction, it is performed by two fairies when they turn into their natural forms and play around.
 * To other Fairies

Offspring
Fairy power can be spread to other Sims around town by mating with a normal Sim or a Supernatural. Genetics play the key role in this. From mating with a normal Sim or a Supernatural, there will be 50% chance that the offspring will inherit fairy power.

Baby fairies do not have wings, but you can tell what wing color a baby fairy will have by the color of sparkles surrounding them. Toddler fairies will have their wings but they cannot do anything as a normal fairy except fairy hover. They also have fairy-styled idle animations such as floating and flapping of wings.

Child fairies can perform four tricks as a fairy to Sims. When becoming Teen fairies, they can then perform other tricks like a normal fairy, assuming that they have a high level of Fairy Magic skill. So child fairies can start to gain their skill by using the four tricks given.

Curing a Fairy
A fairy Sim can be returned to be normal by using the Potent Cure Elixir.

The fairy can also be asked by her/his romantic interest to Forsake The Fae. The opportunity window will appear, explaining what may happen and what to do. Once accepted, they must follow the instructions - fairies usually go to the Arboretum - to forsake the fae, thus becoming normal.

Fairies that have become normal again no longer have any fairy abilities.

Trivia

 * In addition to their wings, their bodies can also glow.
 * Baby fairies don't have wings.
 * There are several new moodlets related to fairies. Some show level of magic warnings, some are related to Lunar Cycle, and some to fairy interactions.
 * The Summerdream family could be considered part of the fairies, because Oberon and Titania Summerdream are both fairies, and all of their ancestors have similar physical appearances, such as the elf ears. However, fairy is not a playable life state in The Sims 2
 * Like Vampires, Fairies age up 5 times slower than normal Sims.
