Because Whirlwind isn't an attack, and doesn't do any damage. I'll fix it again...
[Valour] Spraylet (Female)
Ability: Torrent
Signature Move: Featherstorm
Valour, living out on the ocean, has run into a few tropical storms, but one day, she encountered a hurricane. Valour was flying home after traveling over the ocean, and saw a dark cloud in the distance. It seemed like a regular rain storm, but even rainstorms could be dangerous over the sea. Valour flew faster, to get back to her home in time, but she ran into the storm. It was even worse than she thought, it was a hurricane. She tried to keep together, and felt like her wings were about to be ripped apart. Valour nearly fainted, but luckily, she got to the eye of the storm. Being battered and completely worn out, Valour found the eye of the hurricane to be the most relaxing and calm place she had ever seen. It was like taking crack, and Valour was addicted. Soon, the hurricane passed and Valour recovered. She wanted to experience the eye of a hurricane again, and as soon as rumours of another one started, she went after it. Valour was nearly torn apart again, and just barely made it to the eye of the hurricane. She wearily waited the rest of the storm out there.
After recovering, Valour washed up on the beach close to a nearby town, and was caught by Dragon. She experimented with the idea of hurricanes, and came up with an attack that used the same idea of a hurricane. She ended up with the attack she calls Featherstorm.
Featherstorm is a two turn attack, that can be directed at up to two separate (or not) targets. It’s strongest if directed at just one target. When Valour uses Featherstorm, her wings glow a barely visible light blue, and feathers shoot from them like bullets. Vicious winds whip around her, and Valour floats a few feet off the ground. She’s high enough to dodge Ground attacks.
When Valour is done using Featherstorm, she is tired, and can’t fly for another two rounds, after using up her feathers. Valour can use Featherstorm up to twice a battle.
Type: Flying/ Special / 10% / 95% / Up to two targets / 10% Energy / Lasts three actions
Effects: While Valour is using Featherstorm, she can’t do anything else, and is instantly KO’d by electric attacks in this time. Physical attacks do less damage, the wind whipping around Valour knocks the attacker back slightly, and do minor damage (1-2%). Pokemon under 45 lbs. will get blown back, all other Pokemon over the weight limit have their attacks' damage reduced by 1%. When Valour is finished using Featherstorm, she can’t fly for another two rounds, while she recovers.
Usage Gap: Five rounds, twice a battle.
[Valour] Spraylet (Female)
Ability: Torrent
Signature Attribute: Hurricane Chaser
Valour, being an ocean bird, has lived most of her life at sea, or around the sea. One night, when she tried to fly back over the ocean, a storm hit. But this storm was even stronger than the normal sea storms, this was a hurricane. Valour tried to fly back to land, or find a piece of drift wood, but to no luck. She did her best to keep alive in the hurricane, and eventually came to the eye of the storm. Valour was tired and wounded, and so found this to be the calmest and most enjoyable thing in her life, and waited the rest of the storm out in the eye. When the hurricane passed, Valour wanted to see the eye of a hurricane again and idiotically went after another hurricane. She was nearly torn apart in the winds, and just made it to the eye of the storm.
After just barely surviving these two hurricanes, Valour recovered and found she had a higher stamina for flying, most likely from braving the storms. She avoids hurricanes now, and tries to see the world with Dragon, her Trainer.
She is 5% more likely to get confused, because she gets dizzy easily.
Effects: Valour has a 1% increase in resistance to flying type attacks, and uses 1% less energy for flying and flying type attacks. She is 2% weaker to Razor Wind, Gust and Twister and gets confused by Confusion inducing moves 5% more easily.
Somewhat better?
