I can't find the object lustrous orb

[Pokeduardo]

Hello, I appreciate your help. I meet all the requirements to catch one of the lake Pokémon, but the Lustrous Orb item isn't appearing. It seems I entered the cave much earlier and picked up the item, but it disappeared; it wasn't saved. I've already searched the three locations mentioned in the forums, but the item simply isn't there. I would appreciate your help, please.

Hello @Pokeduardo

 

Apologies for the issue you are encountering.

 

Be sure to be:

As stated here :

Lustrous Orb can be found by entering Wayward Cave on Route 207, here is a screen where to enter the cave. 

 

And more picture, where you can found them in wiki there !

 

Hope it answer your question and dont hesitate if you have further question.

 

Take care,
