Boss Statistics

Overview

• Fight the three instigators of the Mystic Eyes Symphony event as they try to create a perfectly deadly outfit. Each of the enemies will spend 3 turns crafting either a Heel, Statue, or Costume that immensely buffs the enemy party!
• Three break bar Servants are on the field: an Archer (194k, 248k, 303k HP), a Berserker (240k, 288k HP), and a Caster (239k, 284k HP).
• The entire frontline will get a massive 200% ATK debuff that is unremovable for the first three turns! Note this does not affect the back line.
• All three Servants have a special buff they will work towards every turn, as noted by the Trait stack buffs on the enemies, where they gain 1 stack per turn. Once they reach 3 stacks, they will gain powerful buffs!
• Note it is possible to prevent Servants from gaining a trait stack by using Skill Seal, or any Immobilizing effects (Stun, Charm, Sleep, etc.).
• The buffs that the enemies gain also are stronger when more of them have a buff simultaneously, each gaining special additional effects (see tables above) depending on how many other Servants have a piece of the complete outfit done.
• The buff will last 3 turns, after which the Servants will swap the active buff with a new one.
• The Caster's Break effect provides 80% Damage Resist to the entire enemy party! On top of this, she gets 3 turns of Debuff Immunity, and 3 stacks of unremovable 10% Guts. For this reason, it is usually best to leave Miss Crane for last.
• The Archer's 1st Break provides her with 1 turn of Debuff Immunity, and both Crit Damage and Crit Rate buffs for 3 turns each.
• The Archer's 2nd Break gives 2 turns of Debuff Immunity, and fills her NP Gauge to MAX! Be ready for Baobhan Sith's single target NP that can ignore Evade effects!
• The Berserker's Break gives her 3 turns of Debuff immunity, and also will steal all offensive buffs from the Master's entire frontline! Make sure to have Buff Removal Resist to prevent this effect for the damage dealer.

Team Recommendations

• Put damage dealers in the back line for this encounter! The massive ATK debuff that affects the frontline (ATK -200%) lasts for three turns, and otherwise will force the party to let the enemy team finish their first creation!
• ST Damage Dealers are actually generally preferred, due to the effect of Miss Crane's Break Skill. She provides unremovable Damage Resist +80% to the entire enemy party for 3 turns if her HP bar is broken, so defeating the other two before breaking her makes for a smoother run unless Masters have such immense firepower that can overcome the 80% Damage Resist. For higher end rosters, running an AoE damage dealer is still fine (see video links).
• Lancer, Rider, and various Extra (Beast) Classes are preferred for their offensive Class Advantage.

• Buff Removal Resist Support for the damage dealer is crucial before breaking Galatea's HP bar. Galatea will steal all offensive buffs from the entire party, which can entirely reverse the momentum of the battle if Masters are unprepared!
• Skill Seal or Immobilizing Support can come in handy in this battle to postpone the progress of any (or all) of the enemies' crafting progress towards their Heel / Sculpture / Costume.
• The Event Damage CEs Sweat Blood, Flowers of the Sun, and Be Shelved are locked behind the gacha so may not be as readily available, but if Masters have them they will benefit the party greatly. Do note that the rarity of the Servant affects whether they can benefit from the Event Damage bonus.
• An Order Change Mystic Code is immensely useful for this battle simply due to the necessity of placing a damage dealer in the backline. Alternatively, Masters can also use a Servant that is capable of Order Change effects such as Arash or Chen Gong.
