This will use bird skills at an intelligent rate, trying to space them out based on local combat rate, how much MP you regenerate after a battle and how many delicious shimmering moths you have in inventory, then this will attack the monster until it dies. If the monster's defense is too high to hit with your Beak, then the script will use Talon Slash instead. If you are not in Bird Form this will turn over control to the next line of your CCS. Here's an example CCS using this script:
[ default ]
2: consult FeatherExpress.ash
3: note Roc Feather
4: skill entangling noodles
5: skill shieldbutt
That will use noodles/shieldbutt if you are not in Bird Form, otherwise it will use Talon Slash, Wing Buffets and/or Attack with your Beak as it attempts to get a Roc Feather. The note in the consulting script will inform it of which feather to get. Obviously pickpocketing is optional. If you leave it out, the script will work just fine. If you're not in birdform, mafia will simply ignore the command.
There must be a note in the CCS informing the script if it should make Roc Feathers, Buzzard Feathers, Tit Feathers, Penguin Feathers, Phoenix Feathers or Raven Feathers.
