Ok, so apparently the Delta Pokemon guide got deleted or something and there’s no info on the Holon Mountain or any of its Deltas on the Wiki, so I’m posting this here.
I’m in the cave and I see a blocked cave and a bunch off rocks that you can (presumably) use rock smash on, but I can’t figure out what to do from this point on. Based on my research, I know there’s a Delta in here, but there doesn’t seem to be a way to get it. Do I have to just continue on through the mountain and find another entrance, or am I missing something here?
