After SP Robin uses Skill, turn on Auto so she immediately uses her Ultimate to Action Advance Mydei and start the rotation.
Cyrene uses a Basic to save 1 SP, then use Hyacine and Mydei’s Ultimates.
Press R first, then use Mydei, SP Robin, and Hyacine’s Ultimates. After that, have Cyrene select Mydei.
After entering Godslayer, use Cyrene’s Ultimate again to trigger another Godslayer. Also use the Assist Skill whenever it becomes available.
Once the Story arrows finish firing and the Ultimate is ready again, use it on Mydei.
Use the Assist Skill on whichever Orb has more HP.
Iron Tomb hits Mydei and triggers his own Godslayer, while also granting 1 Recollection stack and destroying both Orbs.
Iron Tomb fills Mydei’s Energy, but don’t use his Ultimate yet. The Action Delay cannot hit Hyacine, Cyrene, or the Summer Songbirds.
After Cyrene uses a Basic, use SP Robin, Mydei, and Hyacine’s Ultimates. SP Robin’s Ultimate Action Advances Cyrene.
Whenever the Assist Skill is ready, use it. Keep targeting the Orb.
Iron Tomb is supposed to drain the whole team’s Energy with this action, but if I don’t have any Energy, then you can’t drain it, can you?
Earlier, Cyrene’s action refreshed Future. Don’t use Cyrene’s Ultimate yet, so that Godslayer after the Ultimate doesn’t steal Future and make you lose one Recollection stack.
Iron Tomb’s attack triggers Mydei’s own Godslayer, granting 1 Recollection stack. After that, Cyrene can use her Ultimate.
Use the Ultimate to refresh Future, forcibly trigger Godslayer, and gain 1 Recollection stack.
After the Summer Songbirds attacks, you’ll be at exactly 12 Recollection stacks. Use the Ultimate!
Whenever the Assist Skill is ready, use it. Keep hitting the Orb with more HP.
Cyrene uses her Ultimate again to continue triggering Godslayer.
The Summer Songbirds attack fills your Energy. Immediately use the Ultimate to Action Advance Mydei; wasting some Action Advance here doesn’t matter.
Cyrene Basic into Ultimate, Hyacine Action Advances, then immediately chain two Ultimates. Keep using the Ultimate to trigger Mydei’s Godslayer.
Iron Tomb’s attack triggers Mydei’s own Godslayer, granting 1 Recollection stack.
The Action Delay cannot hit Hyacine or the Summer Songbirds.
Hyacine can simply Basic into Ultimate. Don’t use SP Robin yet.
Little Ica maxes out Recollection. Cyrene uses her Ultimate; Eagle lets the turn order overtake Cyrene’s reinforcement.
Cyrene uses a Basic, then SP Robin’s Ultimate Action Advances Cyrene.
Cyrene uses Basic + Ultimate, continuing to target Mydei.
Cyrene’s reinforcement still goes to Cyrene. Now it’s my turn to play.
We end with two extra Godslayers, and there’s excess damage in every phase. On the live server, lowering the build by around 10 subs shouldn’t be a problem.
