How exactly do you get them?
The amount of EP needed for any worthwhile reward (and by that I mean Eromon) are substantial. I only just got my first event reward Eromon in the last event, only because any chance I had free time I'd run the intermediate 12 stamina mission over and over. That just barely got me past the EP needed for the lowest Eromon.
So are boosters only from the paid Gachas? I had read a guide that suggested you can get with tickets, but I burned all of mine and didn't see a one. I had a quite a few saved up from never really using them before, but now I am left with only 10 R tickets.
