Overall Concept
At it's core, you simply want to trigger Charge as much as possible, and also have your best DPS be on-field to gain the Ultimate Energy as the Blossoms hit the enemy.
For some, you may want to invest most into Zero, Jiuyuan, Hathor, Nanally, etc.
In other downtime, you'll be using the team's skills and ultimates to charge more meter.
Start of Combat Charge
At the start of combat, if all your meters are empty, the easiest way to proc Charge will be to fill Zero's Meter with Skill, then save it until your skill is off cooldown again to quickly utilize 2 Meters.
For example at start of combat:
Zero Skill -> Meter Fully Charged- Swap to Flex Character
Haniel (should not be Anima/Lakshana) - Use
Haniel Skill for buff - Swap to other characters to deal some BAs / Redirects
- Swap back to
Zero - Swap to
Jiuyuan -> proc Blossom - Swap back to
Zero -> Skill -> Meter Fully Charged - Swap to
Hathor -> proc Remora - Proc Charge -> cycle through team's skills and Ultimates for damage
Charge Quick Swap
From here, your Lakshana & Anima characters will naturally gain Meter as well, so you don't need to do the full double Zero skill to proc charge.
When
Hathor Esper Meter is full:
- Swap to Zero -> Trigger Remora
- Zero Skill / naturally fill Meter
- Swap to Jiuyuan -> Trigger Blossom
- Trigger Charge
When
Jiuyuan's Meter is full, simply do the opposite order to trigger Charge again.
