I'm kinda confused on what I'm doing wrong with chaining. I have experience in Diamond/Pearl chaining up to 103, and have chained over 40 for around six species. I'm either very rusty, and forgetting something, or there are new things I'm not aware about.
I've been using
this guide, chaining for Dittos in the Pokemon Village for the last 3 hours yet haven't gotten a chain above 12. My highest chain of 12 right now broke after taking 4 steps south, 2 steps to the right. To a patch of grass which didn't have any objects/borders/corners/holes in the way, but instead at least one radius of grass, when a Noctowl popped up.
I know a new thing about chaining in XY is different shaking rates of grass. I know from experience that entering slow-shaking grass can lead to no pokemon being there, but is it possible that you'll enter the wrong pokemon entirely? If not, what could I be forgetting that I'm doing wrong?
