Managed to cycle the vortex a few more times, coming out with three more chars I did not have. My Valkyrie collection is now complete with the gunner and green hentai chicks joining my ranks. I also got an assassin NBoL that i've been waiting for to try the ultimate in cheese defences (W/A NBoL both with thorns + Desert Maurader).
Still missing out on the chars I've been pining for for months, still have yet to hit a single 5* on any of the legendary souls I've pulled. I'm probably somewhere between 20-30 for this event.
