so far:
1st Map - 17 run: 2 Belinda, 6 Black Fairy, 0 Calliope
2nd Map - 23 run: 5 Odette, 0 Valerie
3rd Map - 6 run: 3 Rikka, 3 Black Fairy
4th Map - 3 run (not yet got Ada & Ruby)
Rikka's map is the easiest since i know my 'weird' luck did drop so many black fairy on 1st map.
it made me think the drop rate's rigged of something.
some ppl cleared it on 1st three run. while ive done more then 20 run on 2nd map yet Valerie is nowhere to be found.
im gonna try different setup of my team on 2nd map like ZeroZet say, but not different team, since ive no way to beat the map without Ninja's help.
