You can now try to capture the legendary Pokemon in Lakes Valor, Verity and Acuity.
The lake will be back to normal now. So surf southeast across the lake to find TM25 THUNDER. Proceed into the cave at the center of the lake. Save your game before fighting it.

| Legendary Pokemon Azelf                                       |
----------------------------------------------------------------
| Be cautious about using special attacks on Azelf. It has low  |
| special defense so it is possible to accidentally beat it with |
| just one hit. When Azelf's HP is down to orange, bring in a   |
| weaker Pokemon and start chipping your target's HP down to    |
| red. Throw Ultra or Dusk Balls to capture it afterwards. Azelf |
| is difficult to catch, so be sure to have lots of Ultra or    |
| Dusk Balls in your inventory.                                 |
----------------------------------------------------------------
If you obtained the TM14 BLIZZARD earlier, then you can surf directly to the cave at the center of the lake. If not, then surf northeast to get it. Once again, save your game before fighting.
----------------------------------------------------------------
| Legendary Pokemon Uxie                                        |
----------------------------------------------------------------
| Bring in a Dragon-type Pokemon to bare the brunt of Uxie's    |
| attacks. Reduce your target's HP down to red, and start       |
| throwing Ultra and Dusk Balls. All Uxie does most of the time |
| is use Amnesia, which boosts its special defense. Again,      |
| capturing this Pokemon can take a while.                      |
----------------------------------------------------------------
Surf towards the cave at the center of the lake. "Talk" to Mesprit and it will run away. From this point on, the chase begins. You can pinpoint the Pokemon's location using the Marking Map Poketech application. The only way you can actually encounter it is to go back and forth between a town/city and a Route. And hope that Mesprit ends up in your location.
----------------------------------------------------------------
| Legendary Pokemon Mesprit                                     |
----------------------------------------------------------------
| This Pokemon is really difficult to capture. When you engage  |
| it, Mesprit will run away on its very first turn. Make sure   |
| that your lead Pokemon's Speed stat is over 100. So that you  |
| get to move first as soon as the battle starts. Use the Master |
| Ball to capture Mesprit right away.                           |
|Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â |
| Alternatively, you can also gradually damage Mesprit until it |
| becomes weak enough to be caught without having to use the    |
| Master Ball. All damage and status ailments inflict on it will |
| be carried over to your next encounter with Mesprit even if   |
| the Pokemon flees.                                            |
