March 7th (The Hunt) synergizes with Xueyi as her Shifu and since Xueyi is Quantum, March can also reduce the Toughness of Quantum weak enemies with her attacks.
Inflicting Weakness Break on parts of Shadow of Feixiao is the key to this battle, so both do well in this regard. Asta buffs the team's SPD and ATK while Lynx heals and cleanses the team's debuffs.

How to Beat Shadow of Feixiao & Ecliptic Inner Beast Boss Fight
Inflict Weakness Break to Remove Safeguard
The Shadow of Feixiao and her summons will receive less damage thanks to their Safeguard talent. To remove Safeguard on an enemy, you must inflict Weakness Break on it.
Inflict Weakness Break on the Resonating Part to Advance Forward
Starting from Phase 2 onwards, you will have to deal with the Resonating Parts. Inflict Weakness Break on the Resonating Part to deal increased damage on it and have all allies advance forward in the turn order.
We recommend inflicting Weakness Break on the Nebula Devourer first to prevent it from inflicting Outrage on your party members.
Inflict Weakness Break on All Parts to Prevent Massive DMG
In Phase 3, the Shadow of Feixiao can use Wreathed in Storm to charge up and unleash Sweep the Heavens, Swallow the Earth on her next turn. This party-wide attack will deal increased DMG depending on how many summons that have yet to be Weakness Broken.
Your goal here is to Weakness Break all of the summons to reduce the damage dealt. You can easily do this by taking out one part at a time since inflicting Weakness Break will advance all party members in the turn order.
