I am attempting to obtain an Imposter Ditto from the hidden grotto in the Giant Chasm. I know how rare they are, but I am determined to capture one.
Other than just biking up-and-back in the chasm and checking the hidden grotto every few minutes, does anyone have any tips or tricks? Can I just save outside the grotto once I'm certain something has spawned and then soft restart until a ditto appears?
Keep in mind that I don't have access to any hacking or rnging abilities.
Thank you in advance!
