Thanks to today's event i already spent about 1.5mil coins in a hour, got +50k team strength and now i've got a problem - i need to bloom some gold girls but don't have elixirs. I already used event one, bought 2 per medals. Missions in search for elixirs give them with about 50% chance (maybe less), but 4 from 5 elixirs are rainbow. Is it ok or i just unlucky? What is most fast and efficient way to farm at least 5 of them?
