• Aglovale (Valentine): 6 skill activations per turn, or 12 with Qilin, all of which being powerful damage skills which boost the overall output of the burst, making him the best partner for the strategy.
• Sarunan (Lv. 100): Many skill activations – 7 in one turn, and 14 if Qilin is called.
• Albert (Lv. 95): Decent amount of skill activations – 6 in one turn or 11 with Qilin. Note that  Lightning BurstGain 1000% Skill DMG Up (Stackable) (1 time)Skill DMG is boosted (Stackable)

• Silva (Light): Can effectively perform another Tactical Relocation on herself after she's used her first two skills, leading to more thorough use of backline member skills. Best placed in the backline first, have her Relocated to the front, and then Blind Spot the unused backline teammate into her place. Also provides Supplemental Damage - but this won't work on Fediel.
• Halluel and Malluel (Summer): Decent supplemental damage if you can get enough Aurora CrestLight magic is amplified (Max: 5 / Can't be removed)
  on Io before the cannon start firing. You may need to bring another source of Crest gain for this to work.
• Jeanne d'Arc (Grand): Decent supplemental damage and cap breaking abilities. Long cooldown time for her best skill don't matter when using Qilin.

Useful summons:

• Halluel and Malluel (Summon): EverbaneBoost to DMG taken / HP is lowered on every turn (Can't be removed)
  Local status effect provides a strong, perpetual enhancement to all of Io's skill damage. Warning: does not work fighting Fediel!
• Belial: Provides good supplemental damage as a sub-summon, but the Max HP loss may be too much to deal with for your team.

Maximizing damage:
The more skills you have, the better, as they provide more skill activations for Staff of Hope. Further improvements come from:

• Supplemental Damage sources, as they will attach to every one of the many hits from Flowery Seven.
• Skill DMG Cap Up sources from Weapon Skills. Viable candidates include:
  • Dark Opus Weapons (4★) or Ultima Weapons: 30% boost with a Skill DMG Cap Up key/pendulum. On Ultima Weapons, the key's effect is applied regardless of the character's weapon specialties. These effects does not stack with each other.
  • Flamma Orbis: Requires equipping as a main weapon. Also requires the MC to not be debuffed, which may be difficult when fighting Fediel.
  • Golden Arts weapons - All have 15% flat cap up and a shared stacking Cap Up cap of 40%.
    • Full Metal Recoil (4★): Strong, but is a Premium Draw weapon and is not entirely practical unless you're lucky and/or have resources to spare uncapping it.
    • Phantom Fangs (4★): Freely available for a limited time during certain Proving Grounds events.
  • Hercules (Light) (4★): Extremely powerful, but extremely expensive to obtain. Note that its Skill DMG Cap Up and skill double-casts only affect the Main Character.
  • Rhongomyniad (5★ to use in grid. Effect works from 4★ as main weapon, but you lose access to Nighthound and  Tactical RelocationSwitch positions of any two allies.): Stamina-based boost to skill specs, and has an Unworldly EX modifier on its first weapon skill.

Priorities

Prioritize the two Healing nodes, then Skill DMG Cap, and finishing with the support skill. Afterwards, the two Critical nodes are good options for increasing damage and increasing double attack is good for charging her charge bar.
