Attacks: Gravity Drain, Earth Strike
(This is a real hard boss, follow this and it will help you beat her.) The fastest way to get her HP down is at the begenning of the fight dont attack just heal and use Raigar's barrier accel. Then on turn two use Raigar's Slash move Karin's Ex move Lohengren and Atsuma's second Ex move Stun Bead Flare in that order if your a high enough level you should do around 1,758 damage or so Doing a good amount of damage (almost killing her.) If you have enough time after then heal Astuma and Karin on the next turn (if she dosnt kill them) and use Raigar's Slash move along with Karin's and Astuma's strongest moves and you should be able to defeat her.
