BOSS - Esmeralda

Esmeralda has a unique mechanic where her attacks seal commands (Attack, physical skills, or magical skills) which can only be removed by breaking her. Red Blade seals Attack, Blue Blade seals physical skills, and Violet Blade seals magical skills. Physical and elemental defense buffs can mitigate damage from these attacks.

Black Blade does not deal damage but applies a counter that kills the character when it reaches zero; breaking Esmeralda dispels this. Esmeralda's other moves include Hack and Slash (three big physical hits to one target) and Five Strikes (five big hits to random allies), which can be deadly to low-HP characters.

Raven's Flight lowers physical defense for all allies. Esmeralda is initially weak to spears, axes, staves, wind, and light. After recovering from a break, she gains two shields and changes her weaknesses. She wastes one action to change weaknesses, cycling through three sets. The second set includes weaknesses to swords, bows, fire, lightning, and wind. The third set includes weaknesses to spears, daggers, ice, wind, and dark.

At half health, Esmeralda uses Black Blade Rush, a party-wide Black Blade with counters of 1, 3, 5, and 7. Keep her shields near breaking point when her turn is approaching to dispel these counters. Five Strikes is the most dangerous move due to its potential to instantly kill characters.

Tips
  • Focus on breaking Esmeralda to remove her debuffs and make the fight easier.
  • Buff physical and elemental defense to mitigate damage from her Blade attacks.
  • Be prepared for the high damage potential of Five Strikes, especially on single targets.
  • Manage her changing weaknesses effectively by switching your party's attacks.
  • Keep Esmeralda's shields close to breaking when she is at half health to counter Black Blade Rush.
