Rune Temple Fatal 12F (21 Turns)

This is pretty tight, and expecting all attackers land critical hits.  So you might need to try few times.   With ★5 Wiggle, it might fail to instant kill 4, and that will offset the timing, so you have to avoid that.  As long as 5 attacks Zenith, that is the aim, and 6 doesn't have to be killed instant, since Alche will finish it up.  If you can instant kill 4, and 6, then you don't need Zenith's counter.  Angelica has to take 2's attack to prevent concentrated fire.
