Dancers are front-line healers, Damage Dealers that can both benefit the party and enfeeble monsters. Not only are they competent fighters, but the TP they accumulate is used to power their various abilities. They execute Dances to heal and create beneficial effects, and perform Steps to inflict negative effects upon the enemy. A touch of customization is added with Flourish, which allows a step to be completed with a variety of bonuses to aid the Dancer and their comrades. Obtained by completing Lakeside Minuet quest.
