The Lamia has been a persistent opponent to many Final Fantasy heroes throughout the years, warping her foes with her vile temptations. In the first Final Fantasy Tactics Advance, you could take control of her and have her turn her allies astray. While the sequel doesn't allow you do to do that, extra care has been taken to make the animation of her "Kiss" attack much more satisfying, as you can see below.
Watch
The kiss itself charms and dooms the opponent. She also has a "Poison Frog" attack which uses her "blow kiss" animation but only shows a heart and a poof of smoke on the enemy.
