yeah, only good for a one-shot nuke (like if you're trying to butcher the raging meter) if someone does use her...
bonus points if you can get extra buffs on her though (done right, my water team can get 11 buffs on her at once, but their grid is not good right now)
pretty much allows def debuff cap on any team if someone can get a decent amount from other sources..
at least 20% can come from ex slot if you can spare it anyway, and that's 45% right there
looking forward to a dark combo with her since i got amon's -25%... no need for any extra if i can get her to burst fast...
