Rusalka is too damn OP on hard. Seep is an instant KO for my entire level 33 party, plus his 40800 HP allows him to survive an entire round of Lighting powered Specials and 3x Aquatic Slayers from Hunter Tiz, 2x Thundara Boosted attacks from Valkyrie Edea (with Lu Bo's Spear) and 3x Thundaras from Red Mage Ringabel.
It's gonna be the first fight where I'll probably be forced to use Bravely Second.
