02:12 - 09:53 Physical team D500
13:00 - 19:51 Magic team D500
The dark-weak variant of the boss has a dispel early in phase 2.
The physical team didn't have problems as each DPS has a source of quick cast to deal fast and heavy damage (Rufus's LMR3, Garland's AASB2, Shadow's DASB).
The magic team didn't got the clear easily though. I had to bring over another source of Hastega in Y'shtola DASB2 and queue it before another action (I put in the Wall Glint+) so that it could be cast after the dispel attack.
For both teams the CSB wasn't applied early so the clears were around 20 seconds.
