And for the second fight I had to reset 5 times to get rid of the sin spawn without loosing someone on turn 1. (Tipp: If a battle goes badly, force close the app. It'll allow you to do the battle over from the start without losing Stamina. It's a cheat, but for some insane stages like this, I don't feel bad about using it as a last resort. Especially if I have to spend Mythril healing after the first boss).
Holy craaap. The boss rush they just added isn't gonna happen for me. As with Phoenix in the last event, I don't care that much about summons anyway.
In good news, I managed to collect 50 Mythril. Just waiting for this current draw event to have a day with equip I want. Looking for Terra's or Vanille's SBs specifically.
