Edna wields her umbrella like both a baton and a shield, and indeed, it can be used to attack or defend. Her martial artes focus on stunning and boosting her stats (including stealing HP and SC). Her movement is a bit slow, but once she gets into the groove of a good combo, she can keep up a string of attacks against a single enemy for quite some time. To make up for her own slow speed, many of her seraphic artes aim to inflict Slow on opponents, giving her a chance to escape for long enough to cast another powerful arte. Many of her lengthier artes are worth the wait because of their high hit counts and wide ranges, allowing Edna to deal multiple blows to multiple enemies with a single attack. As also suggested for Lailah, stacking Sheeld skills to give Edna multiple Iron Stances during casting can be a huge boon in battle, so fuse wisely!
Since Edna knows how dangerous being afflicted with Slow can be, her restorative arte Healing Circle not only restores HP to nearby allies, but also removes Slow. Like Mikleo’s restorative artes, this comes in very handy when you don’t have time to wait for item meters and you need to heal up an ally that is also Slowed.
