Sera Bird

The strongest bird summoner sub-type enemy, and although she lost the ability to summon birds, it doesn't make her any less dangerous. In fact, she could be considered as the most dangerous among the four Sera sub-type Reyvateils, given that her Tempting Dream World skill puts a party member to Sleep and also reduces his or her Defense. She can also use a Lv. 3 Stored Attack called Fall in Love, which causes large Ice-elemental damage. Given the above, cure the Sleep status as soon as you can, and annihilate her before she reduces your defenses to the point in which even a weak attack could take you down.
