Checking your IVs

- The IV Checker can be found in the Kiloude City Pokemon Center. He tells you a ton of information about your pokemon, and understanding it all is essential to creating good pokemon.

- The first thing he tells you is the overall potential of your pokemon. This is simply a measure of all of your IVs added together and is not particularly helpful. "Outstanding" is the highest grade that isn't totally perfect.

- Next, he will tell you your best IV or IVs. All of the IVs he mentions here have the same value, and are higher than any of your other IVs.

- Next, he will tell you how good those stats are. If he says "Stats like that, they can't be beat", it means they are 31. So if he named HP, Attack, and Defense, then said they can't be beat, you have 3 perfect IVs.

- Finally, if you have any IVs that are 0, he will mention them at the end. Otherwise, the last part is the end of what he tells you.

- Go to the Pokemon Storage System afterwards and use the Marking System to mark the perfect IVs on your pokemon. This will be useful when breeding.
