The defense lowering EV berries aren't version or time exclusive, right? I've been checking the Route 10 berry tree for the past week and have gotten all 4 of the other EV berries, but not a single Grepa or Qualot.
you won't believe me, but if you do the same battle against a crabrawler, you will get the same berries.
I haven't really tried to get a large spread and see if it is 100% true, but considering 2 battles with the exact same moves getting the same exact berries (there's like 7 possible berries from that route and you get 3-4 random berries at a time)
Sent out kadabra, used psybeam, kill crabrawler, get a set of berries. SR because they weren't what I wanted. Kill crabrawler with the same psybean, exact spread of berries. SR and switch kadabra with absol, kill crabrawler with slash instead. Gor a different set of berries with the 2 EV berries I needed.
that was last night since yesterday I got no crabawler and the 3 berries I got were all EV berries I ddin't have so I didn't tested. Will test tomorrow to see up to what point this theroy holds true.
