Was messing around with the speed auto clears on the main Discord theorycraft channel and this turned up. This is amp timing and crit dependent to get this low, average time is closer to 2:01-2:06 I think. Can be run at 2x full auto.
GElly enables both Team Str Amp and more than enough Flame Res to facetank all the mechanics. Her buffs fuel the team and SMarishiten throws two levels of Team Str Amp by the time Phase 2 hits. GLuca skill share gives SMari a higher chance of critting for crit fishing.
Tiki gets to skip CoN at phase shift so long as she is shifted, allowing her to benefit from GElly’s full buffs. She primarily chunks away at the Shield Surtr puts up that is only vulnerable to standard autos.
SVerica does SVerica things with her packed S2 and I slap as much strength onto her as possible outside of putting on Bahamut, which would limit DPrep.
SIeyasu is there to assist Tiki in afflictions and enable Bleed for a secondary punisher/DoT, and ideally push Team Str Amp to 3.
When it all comes together, you get a nice 2x full auto that clears roughly every minute. It’s nice~
EDIT: The team I settled on had my lowest clear at 1:45 and cleared 99/99 2x full auto. I gave Tiki Lev for the higher initial damage and swapped the crit print off Ieyasu for Force Charge to try and clear afflictions faster. Time swing is still anywhere between 1:45 and 2:35 (everything goes wrong and they still manage to clear without revives).
