How do you get a moonstone on Pokemon Conquest?
you suck balls!
Skitty will only evolve if you use a moonstone on it. Get a moonstone from the Meteor Falls near Fallarbor town. But be careful you may only use a moonstone once, other Pokemon like Jigglypuff needs a moonstone to evolve into a Wigglytuff. So think carefully if you want your skitty to evolve into a gorgeous Delcatty.
Go to your bag and choose the items pocket. Then choose moonstone. Press use and it will take you to your party Pokemon. If any have their health bar next to their picture, you can use the moonstone to evolve them. Clefairy, Nidorina, Nidorino, and Jigglypuff are a few examples of Pokemon who are affected by moonstones.
The only Pokemon from Black/White you can evolve with a moon stone is Munna to Musharna. Otherwise, you can use a moonstone to evolve these Pokemon from previous generations while they are in Pokemon Black/White. Nidorina -> Nidoqueen Nidorino -> Nidoking Clefairy -> Clefable Jigglypuff -> Wigglytuff Skitty -> Delcatty
