v.137 - Unleashed Update Notes

That's still going to be a problem since V2s were buffed and you need to get her down to 50% HP IIRC to get her to summon. On top of this you'll need to last long enough through her Dark Genesis+pot cooldown- probably best to just find parties, if your party can bind/crash indefinitely you'll all stand a much higher chance of winning.

i remember differently, she still summoned after 1 bil-ish hp had been taken down.
i have no problems with HP, the dark gen-tornado combo is what freaks me out (or bomb-dark gen)
