You have until the end of this season to do it, use it for getting the upcoming also bullshit achievements. We have what, 4 more sets of achievements at least coming up? We only have a few that you need to do with a full 10 floor clear anyway (6 railway packs, 8 canto packs, 8 pack-exclusive fusions).
Maybe the pack exclusive fusions can be done without entering the infinite floors for too long if someone can path that out.
