  • Waterga: Water magic damage to all enemies.
  • Sleep: Inflict sleep to one enemy.
  • Silence: Inflict silence to one enemy.
  • Protect: Increase DEF to caster.


  • See testimonials and discussions.
  • Siren has much, MUCH less HP than other 3★ espers. e.g. She has 97.6% less HP than 3★ Ifrit.
  • Bring a magic cover tank to mitigate most damage. Use reraise or guard against her threshold attack on 80/60/40% HP.
  • Uses Lunatic Voice at thresholds at 80/60/40% HP.
  • While her threshold attack is non-elemental, the rest of her magic attacks are water elemental.
  • Bring protection or cure against sleep and silence.
  • Use DEF/SPR break, and bring dispel if you are using physical attacks as she buffs herself with DEF +100%. Though due to how weak Siren is, this is not necessary and you might want to keep her alive just for the evoke mission.
